The invention relates to mining. Designed for mechanization of processes when conducting horizontal, inclined and rising mining rectangular, trapezoidal and arched forms.

When conducting mining time spent on drilling holes in the bottom reaches 30 percent or more of the duration of the driving cycle, and the time of mounting openings comprise 20-25%. Significant time spent on the drilling of boreholes due to the fact that this operation in most cases is removable drill machines, and when using mine drilling the necessary time to replace equipment in the bottom part of the workings. Execution of works on the construction of the frame supports (wooden or metal) is carried out mainly with the use of manual labor or the use of portable lifting equipment, overhead or ground of Krepostnaya. The fastening openings anchor support is possible with the use of portable drilling rigs or drilling, and the train is associated with more time spent on the replacement of equipment in the bottom part of the workings. It should be noted that the implementation of these activities over time, as a rule, not combined with other operations of the driving cycle.

From the foregoing it follows that the use of separate mechanisms, machines and equipment for mechanization of drilling holes in the bottom and under the anchors allows you to facilitate the work of the drifters and reduce the time to perform these operations by increasing productivity. However, consistent rotation for loading blasted rock or intermittently perform the same operation for the production of another does not give a significant reduction in the duration of the driving cycle. In addition, when carrying out excavations drilling and blasting method it is necessary to erect temporary protective lining in the area of people, which also requires time. In this regard, the ultimate effectiveness of the process of drilling holes in the bottom and under the anchors and mounting mine in the tunneling loop is determined by the interface capabilities of this part of the equipment handling part.

In the tunneling drilling and blasting sets (Progressive technological scheme of reservoir development in coal mines. Album. M, IGD them. A. A. Skochinsky, A.A., 1979, - S. 245), to anoy the loader, and so D. In the process of excavations need to replace machinery and equipment in the bottom part of working. The main disadvantage of the layout of the considered sets is relatively long duration of support operations, resulting in increased duration of the driving cycle and the pace of the workings.

Known tunneling drilling and blasting kits that allow you to reduce the time spent on the operation of loading rock mass. The peculiarity of the considered sets is that the loading of the rock mass is a parallel operation of two loading machines (Loading machine in mining industry. / C. D. Irasci, O. P. Ivanov, A. S. Logvinov and other Novocherkassk, CUI, 1978, - S. 13, S. 16, Fig. 2, 8, b). The disadvantages of these sets: the sequence of operations of the driving cycle - loading of the rock mass, then mount the generation and subsequent drilling of bore-holes; the impossibility of carrying out operations during the ventilation openings. In addition to these shortcomings in the kit is not provided reliable protection working bottom space from possible fallout pieces of the Cai and technological scheme and transportation of rock mass on the ongoing development is a set of mining equipment (Machinery and technology gornoobogatititelnyh works in the coal industry, Ed. E. E. Nilly. - M.: Nedra, 1991, - n-212). Consider the set of equipment consists of drilling machines, loading machines batch and tunnel conveyor. Loading of the rock mass is bucket loading machine that operates in a load-haul mode. The machine carries out the delivery and loading rock mass on a continuous belt or chain conveyor, located at a distance of garbage rocks from the bottom and lengthen as it podvigina. Bucket machines produce the cleanup of the soil, thus completely eliminates heavy manual labor grinding production and rasstanovka transport communications. The loading machine is also used for shipping items lining, tightening frames with backing Sakrebulo space. Racks and vernaci arches hang on the special side arms of the machine, and the tightness and the hardware is placed in the bucket. Lifting and installation of the roof bar is made with the help of the bucket of the machine on which the pre-fix is a special device with hinge, ensuring the correct position of the roof bar corresponding to the installed racks and direction. Loading machine and a drilling machine razmenivayas freely in the following:

1. The lack of pipeline rigid rod that does not allow you to place it any equipment, i.e., the space above the conveyor remains unused.

2. The impossibility of combining the operations of loading rock mass with airing generation, because the design of the pipeline does not allow the operation srivanalai, which leads to additional time for serial execution of these transactions.

3. Partial mechanization of the construction anchor lining, because the use of the loading machine for delivery and lifting Varnakov does not eliminate the need for heavy manual labor in ancarani and installation of the lining.

4. The need for operations to exchange the equipment in the mine, which leads to additional time spent on the turnout machines.

5. The remoteness of the pipeline from slaughter, which requires additional time for delivery blasted rock from the pile to the conveyor.

6. The absence of mechanization of loading and zapalski holes, which leads to additional costs of manual labor drifters.

7. Use of the loading machine for shipping items lining and mount the conditions and mounting, because the possibility of their combination.

The aim of the present invention is to increase productivity, increase the rate of penetration and the level of mechanization of work when carrying out horizontal, inclined and rising mining drilling and blasting method.

These objectives are achieved by the application of the system of mining machines, providing a combination of operations of loading rock mass, drilling blast holes for anchors or bottom and erection anchor or polaramine-anchor lining with tension, as well as a combination of loading and ventilation output. Moreover, the proposed system of mining machines allows to mechanize the operation of fastening and to exclude the operation to exchange the equipment in the ongoing development, as well as to mechanize the loading and saigoku holes.

According to the invention, this is accomplished by the fact that the system of mining machinery consists of subsystems branch of the rock mass, the cleaning of the rock mass and fixing the formed space, and differs in that subsystem separation and cleaning of the rock mass is made in the form pureprogressive modules, including self-propelled loaders periodic casteli hard rod and device for the exchange of trolleys, and subsystem fixing the formed space is made in the form of a monorail platform with lifting device, cassettes tightening and installation forks with verhnekame lining.

Bottom scraper loader is located on the axis of generation, and borophaginae modules are arranged symmetrically with respect to the loader, which ensures their Basmanova work.

Drill module is located on the bottom of the reloader with the ability to move his rod with his mechanism and runs in the form of a self-propelled base support frame with mounted on it, drill machines, cartridges tightening and mounting plugs with verhnekame lining.

Monorail platform with lifting device mounted for movement along the guide beam, fixed at the roof bar of arch supports or anchoring rods along the axis of generation, and is intended for installation and dismantling, loading and sapiance holes and fastening operations held for the production, which gives the possibility of combining the operations of loading and fastening and thereby reduces the time the driving cycle.

Bottom of Skrepka the opportunity to start cleaning the rock mass from the bottom till the end of time airing of manufacture. The loader has a mechanism semiperiodic and don't need a permanent capacity.

The combination of the operations of loading rock mass and drilling blast holes for anchors or bottom is due to the fact that the loading is carried out wedge loading toe loader and bucket Executive bodies poroporoaki modules and drilling holes - drill module and drilling equipment poroporoaki modules. All of the above equipment is in development and has the ability to combine their functions in time and space.

Simultaneously with the loading of the rock mass and drilling is carried out construction polaramine-anchor lining with metal mesh or glass cloth tightening using krepemontazhnogo equipment. Tapes tightening placed on the base support frame of the drilling module and the lifting device on the monorail platform. On the base frame of the drilling module in the installation forks placed vernaci lining, which in turn, by means of the lifting device is removed, and then moved along the axis of generation and climb to the roof, they draw tight and installed on predvaritel pump group includes nosochnoy station, oil tank and so on, and next, in alignment with the loader, is a device for the exchange of trolleys, which represents a track with strengthened by the forks and a spare line.

The proposed system of mining machines allows to achieve a high level of mechanization of all operations of the driving cycle, increase productivity and increase the rate of penetration of preparatory workings.

Significant differences are:

1. The system of mining machinery for carrying out horizontal, inclined and rising workings drilling and blasting method consists of subsystems separation and cleaning of the rock mass and fixing the formed space. Subsystem separation and cleaning of the rock mass is made in the form poroporoaki modules, drilling module, the bottom surface of the scraper loader and device for the exchange of trolleys and subsystem fixing the formed space is made in the form of a monorail platform with lifting device, cassettes tightening and installation forks with verhnekame lining.

2. Borophaginae modules are arranged symmetrically with respect to the loader, which is respcctive with mounted on it two drilling machines, cassettes with tightening and mounting plugs with verhnekame lining, which is located on the bottom of the loader can be moved along the rod by means of its mechanism.

The principle of operation of the proposed system of mining machines is as follows:

After completion of the drilling face borophaginae 1 and drill 2 modules are drained from the bottom to a safe distance, and monorail platform with gruzopodyemnye 3, together with wedge loading module 4, is pulled to the bottom to prepare for vzryvayut. In the process of loading holes BB on the installation of the plug 10 set vernaci lining 11 and the cassette 9 is placed puff. After loading holes monorail platform 8 is drained from the bottom at a safe distance.

After blasting, during the airing of production, the bottom material handler 3 through V-pogruzchiki module 4 starts cleaning the rock mass from the face. At the end of time ventilation in the work take borophaginae modules 1 and make the cleaning of the rock mass by loading her bucket Executive bodies on the conveyor 3, which transports mass on the ongoing development and saturate it in the trolley 16 supplied under the tail part material handler 3.

As outcrops of the roof, drill machine 13 drill module 2 is installed in the position to drill blast holes for anchors and produce the drilling of several boreholes.

Simultaneously with the production of the work of unloading of the rock mass from the bottom, drill blast holes for anchors and anchor installation lining is the construction of a permanent polaramine-anchor lining with tightening using the aid of the lifting device 8, picking up the tension, put on previously fixed anchors. These work when performing the driving cycle repeated several times.

Before completion of the loading of rocks, when exposed upper part of the face, drilling machine 7 poroporoaki modules 1 are served ahead and proceed to perform the drilling of boreholes for the slaughter". At the end of the process of securing production, drilling module 2 is applied to the bottom and drill machine 13 also begin to perform the drilling of boreholes for the slaughter". After the operation, the downhole drilling cycle of works on carrying out excavation is repeated. The capacity of rail track can be performed in the repair and preparation shift.
