The invention relates to the mining industry and can be used in the development of ore, gravel, coal, oil-shale deposits of construction rocks, construction materials and some other solid minerals.

Known conventional methods development of solid mineral deposits, composed of rock and half-rock rocks, loosening which is carried out using large-scale explosions and nutrition which is only 3-6%, as well as negative environmental impacts [1], [2].

In recent years began to appear technology development of solid mineral deposits and mining operations, based on the use of blasting rocks with subsequent use energy explosion.

In particular, there is a method of destruction of rocks by explosion [3], including the sinking of wells or bore-holes, the charging of explosives and blasting with blasting horizontal layers. Before blasting compresses the ledge on the side of the slope and the top and framing compressed volume of rock under a given angle method deliverative. Perform sequential blasting from the top down. The capacity of each of the next exploding layer of rocks increases proportionally to the mass prigruzki blown from the overlying layers. For the implementation of the method is used blasting unit, incorporating the equipment for drilling, charging and blasting holes (holes), and a device for crimping the ledge and to absorb the energy of the explosion.

In this way part of the explosion energy is used for crushing objetych rock ledge, however, the remaining energy is repaid underride devices and, basically, not iusi operational intelligence, differentiation by quality, by drilling holes of a certain diameter and choice of power charges depending on conditionnot minerals, blasting wells for mobile shelter and selective excavation processing blocks.

The disadvantage of the prototype is incomplete, the energy of the explosion.

Thus, to the General disadvantage of all of these technologies mining operations with explosive destruction of rocks can be attributed to the low energy of the explosion.

The technical result of the invention is to improve the completeness of the explosion energy, the efficiency of the explosive rock breaking, mining of solid minerals in General and the various construction activities associated with the destruction of natural and artificial hard material by blasting.

This technical result is achieved in that in the method of development of deposits of solid minerals, including operational intelligence division of the rock mass within each working horizon career field operational units, drilling operational blocks horizontal or slightly inclined wells, loosening MgO explosive charge under damping shelter, selective mining blown blocks, preparation and processing of minerals, drilling operational blocks producing wells, the diameter of which is in the range of 50-150 mm, with the grid set to ensure the selective crushing of rocks, wells charge nizkobyudzhetnoy explosive mixture and initiate the laser pulse through an intermediate piece through a system of laser initiation perceive the released kinetic energy of the explosion and the resulting dust and gas emissions damping device, convert and transmit it through accumulating device on excavation device used when performing excavation and loading and auxiliary work and when loading of the rock mass in progruzochnye capacity, which is placed on the upper platform of the working bench, with use of mobile plant including a drilling rig, a device for charging wells, the laser system initiation, the damping device excavation the device, the device energy conversion, storage device and progruzochnye capacity.

A comparable analysis with the prototype of the differences is in on a particular net, charged with their explosive mix of low presentati and initiating charges laser pulse, as well as in the use of the mobile unit, which includes almost everything needed for field development design elements, such as for drilling and charging wells for initiation, for the perception of the energy of the explosion and its further use.

Thus, the inventive method development of solid mineral deposits corresponds to the condition of novelty. In the study of other solutions in this field of engineering not identified the features that distinguish the invention from the prototype and aimed at achieving the claimed technical effect, and therefore they provide the requirement of inventive step.

Method development of solid mineral deposits is as follows.

Carry out operational intelligence, on the basis of which we distinguish, within each working horizon 1, operational (development and production) blocks 2.

Operational intelligence can perform consistently in three stages.

In the first stage - leading operational intelligence, which is done by drilling and sampling workings special purpose furrows, ditches, wells, or perebor blastholes are working and the overlying horizons, resulting geological information used for allocating operational blocks 2 within the array of rocks to be mined or planned development horizon 1.

In the second stage, carry out the current operational intelligence that accompanies mining operations using operational drilling wells and sampling traditionnels excavation and loading and formation of internal transport flows of mineral raw materials, consisting in establishing operational mine geologist spatial position of morphologically altered blowing items of minerals, for example, ore bodies, or portions thereof, based on the parameters and the form of the collapse of using nomograms, the contour of the ore body or coal seam, in the collapse of the set of landmarks that serve as the reference point for the operator excavating device.

After separation of operational blocks their amerivault horizontal or slightly inclined wells 3, the diameter of which is in the range of 50-150 mm, This range allows you to divide all of the wells in diameter into three groups 50-70, 70-105, 110-150 mm

During development, depending on the occurrence of ore bodies or their individual elements, properties of rocks and other geological and mining technical features working units, it is possible to use a combination of wells of different diameters and tilt in a row or between rows.

Drilling is carried out using a drilling rig 4 mobile unit 5, including applied in mining drilling equipment rotary, percussion-rotary or roller types, each of which is used, depending on Burevestnik rocks clarify on the basis of information operatively received in the process of drilling wells.

Drilled charge nizkobyudzhetnoy explosive mixture, when using the device for a loader 6, mounted on a mobile unit. Device for loading 6 can be based on the equipment charger machine operated mines.

Exercise loosening rocks short-delay and dispersed downhole blasting and miradero charges of explosives (e) under the damping cover 16, thus initiating the explosive charge laser pulse transmitted through the intermediate piece by means of the laser system of initiation, which is also mounted on the mobile unit.

Released after initiation of the kinetic energy of the explosion and the resulting dust and gas emissions perceive campfireusa-power unit 9 consisting of a damping cover 10 that has a damping device 7, which, in turn, is mounted on the damping of the cover 16, which provides selective blasting mining blocks. Part campfireusa-power unit 9 includes a device to convert energy 10.

After conversion and accumulation Eni performing excavation and loading and auxiliary work and when loading ballast rock mass 18 in progruzochnye capacity 15.

In Fig.2 shows the device energy conversion 10 campfireusa-power plant 9, including a system of interconnecting the flywheel 11, the system pressure of the friction plates 12 fixed on the bottom plate 13, through which the kinetic energy of the explosion is released in the form of a motion blasted rock and dust and gas emissions, perceive and transmit system interconnecting the flywheel 11, the promotion of them, where the energy is accumulated in the form of mechanical; the basic design of the flywheel and the principle of their action, and their use in a number of machines and mechanisms, refer to the source [5]. The kinetic energy stored in the flywheels, convert to the cumulated energy of compressed air (or other, less safe and cheap gas) through a system of movable rods mounted on the upper (moving) plate 17, and a system of cylinders attached to the bottom 14 peregruzochny capacity of 15.

Hold the cylinder campfireusa-power unit 9, which is formed and accumulates the energy of compressed air in a relatively fixed position when the blasting of rocks is carried out using peregruzochny tank 15 filled with ballast rocks 18-and is movable relative to the set over it the second plate, carrying ballast mountain mass, vertical walls, the front of which is pivotally secured in the upper part of the vessel and, if necessary, using it to form a discharge gap for exemption from ballast rock.

However, as described above, the drilling unit 4, the device for charging wells 6, the laser system initiation, the damping device 7, excavation device 8, the device energy conversion 10, a storage device and peregruzochny capacity 15 are part of the mobile unit 5.

This ensures high-quality crushing rocks, selective excavation practicing blown production unit and divide it up into homogeneous mini-blocks and selective vnutrikabinnoe the recess of the rock mass within the mini-blocks; notisable and mezzanine averaging of different sorts of mineral raw materials on a separate grade, but excluding the averaging of different types of mineral raw materials; averaging career, preceramic and preparing warehouses and piles, preparation and processing of minerals.

Thus, the inventive method of development of deposits of solid minerals enhances the completeness of A. The method can be used, in particular, when developing chinea deposits of vanadium bearing titaniferous magnetite ore represented by the rocks of the rock types, ore bodies of the complex structure and material composition.
