Selective ore excavation method
SUBSTANCE: invention relates to mining industry and can be used at formation and stabilisation of ore quality at a stage of mining operations. The method involves determination of coordinates of a bucket of a mining unit, content of a useful component in the mined rock in the bucket of the mining unit as a conditional mathematical expectation of content of the useful component at an excavation point, which is determined as per results of preliminary testing of a network of wells in vicinity of the excavation point with determined coordinates, loading of the transport vehicle and its addressing to unloading sites considering content of the useful component in the transported mined rock. Depending on position of the mining unit in relation to location zones of technological sorts of the mined rock in a working face, a possibility is established and a task is created for predominant excavation of a certain technological sort at loading of the transport vehicle, in compliance with which positioning of the bucket of the extraction unit is performed in the working face at excavation; besides, mining-out of the rocks of the working face is started from an outline between technological types of the mined rock, the position of which and location zone of technological types is specified by geophysical methods during excavation as per the analysis data of the mined rock in the bucket of the mining unit.
EFFECT: improving parameters of quality and excavation of technological sorts of ores and mined rock for ore sorting.
The invention relates to the mining industry and can be used in the formation and stabilization of the quality of ore at the stage of mining operations.
Known technical solutions, with controls specified volume and quality of the rock mass, but not the decisive task of creating a quality ores, selective extraction of different sorts of rock mass (F. N. Salov, B. I. Ermolaev, I. P. Semin in. A. Kryuchkov, V. A. Viktorenko, E., Artemyev, A. M. Galkin, A. D. Lenski, C. M. Stolyarov, A. with. The USSR №750531).
The known method of selective extraction, including successive portions of the ore excavation with separate extract different portions of a single-bucket excavator by introducing his bucket in the slaughter and subsequent quality control of rock mass using installed on the excavator bucket sensors (Popov, N. and other mining of radioactive ores. M, Atomizdat, 1970, S. 50-75). However, with this method information about the quality of the rock mass in the ladle is produced at the end of the process unit decreased, when the formation of the loss or dilution of minerals in the drawing has already happened, and is only used to select the direction of movement of the rock mass.
The known method, which involves geophysical methods advanced testing of the quality of the rock mass of each portion of sherpani the front of the bucket, with the subsequent adjustment of its position during all operations decreased (Century, Sekisov, A. A. the gas-discharge Chanel, and.with. 1133400).
The known method of selective extraction, in which a preliminary analysis of geophysical methods the quality of the rock mass located in the immediate vicinity of the ladle in the area of zacheciani produce two independent systems of sensors installed respectively on the external design of the bucket and the bucket (Century, Sekisov, A. A. the gas-discharge Chanel in. A. Minakov, A. with. 1631175). Existing geophysical methods of sampling, typically require a significant amount of time measurement, the accuracy of measurement at low content of useful component is often not satisfactory, moreover the results can represent the volume of the rock mass directly in front of the sensor and not the whole mountain mass of the bucket. Thus, these technical solutions in relation to the development of the absolute majority of non-ferrous metals are lag sampling and low accuracy of the measurements.
Closest to the claimed technical solution to the technical essence and the achieved result is a method of controlling transport in open pits at the selective extraction of ores, including the determination of the content of the useful component is enta in rock mass in the bucket excavation tool, loading the vehicle and its addressing the objects of the discharge with regard to the content of useful component IC transported in rock mass. The method comprises the additional determination of the spatial coordinates Xi, Yi, Zi bucket excavation tool at each point of the excavation, and the content of SC useful component estimate by the formula
where Ci is the conditional mathematical expectation of the content of useful component at the point of excavation, as determined by the results of preliminary testing of a network of wells in the vicinity of the point of excavation to the above-mentioned coordinates Xi, Yi, Zi; N is the number of buckets loaded in the body of the vehicle (A. C. Cancel, M. A., Cancel, E. M. bogushevsky, V. I. Kekushev, A. J. Chervonenkis, V. L. Gurevich, A. N. Tricin, N. And. Kucharski, E. A. Tolstov, A. P. Mazurkiewicz, RF patent №2100844).
It should be noted that the speed of operation of this technical solution depends on the speed of determining the spatial coordinates of the bucket or constrain the process of excavating the rock mass, but it does not guarantee the issuance of reliable data on the content of useful components in the ladle, so as not uchityvaetizmenenie movement and possible mixing of the ore host rocks in the pre-explosive fragmentation. In addition, the decision to addressing the loaded truck shall be based on the results of the download. At the same time, no mechanisms of control and material composition of the rock mass loaded transport capacity is not provided. When determining the grade of the ore for further addressing is not taken into account and also the utilization of the bucket during excavation of varying quality rock mass that falls into one of the transport container.
The objective of the invention is to develop technical solutions, allowing for the development of complex-structured fields to keep separate the notch of various technological varieties of ores and, in particular, not only to shape the quality of the flow of ore to the beneficiation plant, but also to form the stream quality of the rock mass on the lump sort. This requires registration of the quality of portions of the rock mass with a lower content of useful components.
The task is solved in that, depending on the position of the excavation tool relative to the zones of localized technological varieties of rock mass in mine to decide whether to form a task for pre-emptive seizure of certain technological varieties when loading the vehicle, whereby carry out the positioning of the bucket excavation tool in the face at drawing, and beginning the tons of development rock bottom with loop between process types of rock, the position and areas of localized technological types specify geophysical methods in the procedure according to the analysis of the quality of the rock mass in the bucket excavation tool.

Examples of specific performance
As the reserves are rich deposits throughout the testing involved a wide range of different poor technological properties and require separate processing of R is D. This increases the relevance of lumpy sort ores at the stage of mining operations, which involves basortulu the recess of rich ores, the flow of which is normally sent (after averaging) on the concentrator. Separately formed and sent to lump sorting threads ores or razboieni rock mass from the contact zones.
The task of forming different threads of the rock mass makes to their quality increased requirements. One of the main parameters is the content of useful components and impurities. Streams of rich ore and razboieni rock mass significantly differ in the content of useful components. The most difficult is rugosities poor or razboieni ores from the contact with the host rocks of the area. To obtain satisfactory results in the ores with a low content of useful components required duration of the measurement contents of the most useful components does not fit into the operative time decreased significantly hinders the performance of the process of excavation.
It should be noted the different approaches of the proposed technical solutions in comparison with analogues and prototype, which ensures the achievement of the claimed positive effect. Known and described VisualAge selective extraction of ores provide to ensure the required quality of the rock mass correction of the trajectory of the bucket during use. Thus, the required (sufficient) check the content of useful component in the bucket on the technological requirements should be much less time bailing. Time to stock up for excavators is 7-15 with, which is usually not enough to register the content of useful component.
The main advantage of the prototype is the lack of necessary operational check of the contents of geophysical methods of testing. The speed of decision making is reduced to the speed of determining the spatial coordinates of the bucket, through which the results of preliminary testing of a network of wells in the vicinity of the point of excavation is determined by the content of useful components in the bucket.
Thus, the technical solutions adopted for the prototype, not hinders the process of excavating the rock mass, but does not guarantee the issuance of reliable data on the content of useful components in the ladle, as it does not take into account the spatial displacement and possible mixing of the ore host rocks in the pre-explosive fragmentation. I.e., this technical solution is not provided for adjusting contours technological types of rock mass in the bulk.
The main qualitative difference between the proposed technical solution from the prototype is a constant adjusted the e provisions of the contours technological types of rock mass in the bulk. While the proposed solution is not associated hard time process decreased when measured by geophysical methods content of useful components in the bucket loading facilities. Check the content of useful component in the bucket excavation tool can continue filling the bucket and turn to the transport capacity up to and including discharge. Given that the share of stock in a loop loading means is less than 30% for excavators, and loaders even less, then check the contents of useful components in the rock mass according to the technology proposed technical solution can be increased at least twice. The results of these measurements are solved two problems:
1) updating information about the spatial position of the path between technological types of rock mass, position, areas of localized technological types of ores;
2) the Characteristic quality of the rock mass in the body of the vehicle.
Check the content of useful component in the bucket excavation tool can last for a large part of the cycle from the filling of the bucket to discharge into the vehicle. It should be noted that the ratio of different technological types of rocks in the process of filling of the bucket can be changed, is changing, and the average content of the W useful component in the rock mass of the bucket.
The process of refining the contours technological types of rock mass provides the following operations:
- Determination of the coordinates of the bucket during use;
Check the content of useful component in the bucket for the period from the filling of the bucket to discharge into a transport vehicle;
Writing of the results of operational testing in the database;
- Clarification of contours technological types with respect to the direction of break-down and current measurements of the trajectory of filling the bucket, the quality of the rock mass in the bucket excavation tool.
Testing of rock mass in mine start with areas expected position of the contours technological types of rock. The position of the contours technological types of rock clarify in the process of excavation according to the spatial movement of the bucket when it is full, and geophysical data sampling of the rock mass. And check the quality of the rock mass in the ladle is carried out in the period from the filling of the bucket to discharge into the vehicle.
The filling of the bucket occurs during movement along a certain trajectory. The beginning of the filling of the bucket can (for excavators EKG) be fixed by the values of the motor currents of the head, lifting and turning, as a time of increasing values of current engine hoist and pressure by reducing the motor current p the gate. The completion of filling of the bucket is logged when a sharp reduction in motor currents of the head and lifting and increasing the current engine rotation. Check the quality of the rock mass in the bucket excavation tool is made without compromising performance throughout the cycle. Advancing excavation of rocks between technological types of rock mass with simultaneous refinement of the provisions of these circuits allows a more precise focus position of the excavation tool relative to the zones of localized technological varieties of rock in the mine, or rather to establish the possibility and generate job pre-emptive seizure of certain technological varieties when loading the vehicle, whereby carry out the positioning of the bucket excavation tool in the face at drawing.
Advancing excavation of rocks between technological types of rocks with simultaneous refinement of the position of the contour helps to improve the performance of selective extraction. For example, when the notch is rich ores forming flow to the treatment plant with the simultaneous formation of flow razboieni ore (with the boundaries of the ore - rock) on lump sort it is important to ensure the quality requirements of one and the other threads of the rock mass. The displacement path in the direction of rich ores HC is licit burden (costs) on rugosities, additional loss of useful components. The displacement path in the direction of waste rock will increase the dilution of ore flow to the treatment plant and will reduce the effectiveness of rugosities, will increase the content of waste rock in the United stream of the rock mass to the beneficiation plant.
Depending on the provisions of the mining resources in the face relative to the zone of localization of different technological types of rock is the possibility of extraction of certain technological types of ores for loading vehicles mountain mass of a given quality. This feature is set in automatic mode or in dialog mode driver program. In particular, when establishing the ability to load transport capacity of a specific technology type can be considered real merit configuration of Nabal rocks in the bottom, which are continuously updating operational testing of geophysical methods with fixing the position of the bucket in the mode of filling it rocks.
On the basis of its capacity load transport capacity of the mountain mass of certain technological varieties in the mode dialog or programmatically generated target on the primary notch technological type.
During the boot process, transport cf is DSTV, geophysical methods determined by the content of useful components, impurities, elements that characterize technological type of rock. Characteristics of the rock mass (with respect to a specific technology type permanently installed in the load transport capacity by the ratio of the mean contents of useful components, impurities, elements that characterize a specific technology type. The average content of the above components are installed according to the formula, which in addition to the ratio of the components listed above takes into account the degree of loading of the bucket.
In Fig.1 presents an automated process control system of selective extraction of the mining unit, which has two components - fixed and mobile. Communication between them is carried out through the blocks of the broadcast data (4 and 10). In preparation of the draft mining mining unit (according to in-situ testing using the subsystem GEOMARK (3)) is preparing a digital model that is loaded into memory Botova computers loading means engaged in the practice block. Access to data of a digital model of a mining block is via a module (8). The positioning loading facilities and its working body relative to the contour and areas Loka is Itachi technological types of ores is carried out by high-precision positioning equipment running module (15). Selective cutting unit is carried out according to the planned (using block 6) the volume of production of ore types. The ability to load transport capacity in a certain type of ore (rock mass) is determined depending on the position of the excavator relative to the zone of localization of this type of ore or rock. Job loading process type of rock set in dialog mode driver system using block (14). The position of the contours and areas of localized technological types of rock specify in the operations of the stock and rotation of the bucket for unloading geophysical methods.
If in the process of filling and moving the loaded bucket, the system registers the quality of the rock mass in the bucket, do not satisfy the established job load transport capacity, then the command is given for unloading the contents of the bucket into the appropriate stack without loading transport capacity. Therefore, according to analysis of the quality of the rock mass in the bucket excavation tool adjusts the position of the contour of the excavation and containment areas of technological type of rock. Thus, collaboration RAM assay (12), determine the load of the bucket (13), high-precision positioning (15) analysis and control of excavator (9), clarified the possible mapping of the mining unit (11) creates conditions:
1) the job to load the transport capacity of the mountain mass of a given quality;
2) clarifying the borders of zones of localized technological types of rock mass, minimizes cycles preexcavation and maximum cycles ending loading of the rock mass in the transport capacity;
3) increase the efficiency of selective extraction and subsequent processing of ores.
The presence of blocks of the broadcast data (4, 10) ensures rapid transfer of data on the quality and volume of the rock mass is loaded transport capacity and its addressing. The joint work of the accounting modules of the grade of ore extraction (7) and planning module varietal extraction of ores quickly generates priorities priority excavation of rock mass defined types.
The claimed solution now in the process of selective extraction of ores during the development of complex-structured deposits provides higher quality and extraction process varieties of ores and rock mass for rotocontrol.

Implementation of independent processes of location of the hoppers is carried out by moving the frames of the hoppers in a vertical plane and the hopper carriages - in the horizontal plane and is controlled by the vertical movement mechanism and horizontal movement mechanism. At that the hoppers by means of articulated linkages with carriages are pivotable in a vertical plane by means of telescopic mechanisms of rotation. The hopper frames when moving interact by sliding bearings with vertical guides. The complex is equipped with vertical guides of the frame of the modules, which interact with the sliding bearings of the frames of the hoppers, the mechanisms of vertical movement connected with sliding bearings, the mechanisms of horizontal movement, mounted on the frames of the hoppers and connected to the hopper carriages for positioning the hoppers in the horizontal plane, and telescopic mechanisms of rotation of the hoppers in a vertical plane relative to the hinge connections, the system of automatic control of mechanisms of the complex functioning. The complex also is equipped with positioning sensors mounted on the frame of the complex and connected to the automatic control system, and to control loading the hoppers with rock mass on the bottoms of the hoppers the control sensors are placed. At that the automatic control system comprises a microprocessor with a control unit, a control panel of hydraulic system and electric generator.
EFFECT: improvement of the process efficiency of the complex operation for loading of the rock mass in the dump trucks.

SUBSTANCE: proposed sorter passes the flow of product particles through the concentrator onto tapered scattering plate which feeds the product in the form of a uniform, circular monolayer to collimator comprising a product inner and outer guides to create a circular flow of products directed vertically. There is a unit of detectors in the said flow of products comprising an upper detector and optical unit (33). A rotary beam-splitting mirror is fitted below the said optical unit to scan the product in the circular zone of registration. The product passing through the registration zone is bombarded by the source, and the signal from the reflected or passed light is then measured by the detector of unit of detectors and optics. The classified product is removed from the flow by a rejecter in response to the control signal of the pickup incorporated with the aforesaid unit of detectors and optics. The classified product comes into the bin towards one side of the separating plate, the remaining products being directed free into the said bin.
EFFECT: higher quality of products sorting in flow.
