(54) METHOD OF OPENING AND PREPARING COIL LOGGING

PLASTGOTGAM blocks; main central trunks are conducted either on average or in the lower blocks. FIG. Figure 1 shows a scheme for dividing a mine floor into blocks; FIG. 2 is a schematic view; in fig. 3 preparation scheme. The method is as follows. The mine field is divided into blocks 1-9. Blocks 2, 5, 8, arranged in the fall range, simultaneously open the main skip 10 and cage 11 trunks, as well as paired block air supplying 12 and ventilation 13 trunks. At the same time, the skip shaft is led to the penultimate horizon, and the cage one - to the drainage-ventilation horizon of the lower unit 8. When the main and cage trunks are constructed, a near-stem is built. yard 14. The main outgoing horizon is constructed and equipped for the entire life of the mine. The seam on the second horizon is opened with two parallel crosscuts 15. Coal from the first horizon to the second is transported along the bremsberg 16, from the third horizon to the second horizon - along an inclined conveyor pit 17. The drainage-ventilation horizon is served through a cage shaft and a crosshead 18. For maintenance of the first horizon passes a complex of inclined workings 19 on the second horizon. In each of the blocks, by the time they are commissioned, the lava 20 is cut into the blocking barrels directly at the block trunks. At the same time, the cleaning faces of the mine are equipped with 1P) 1 MI complexes or aggregates. The main field shafts 21 are conducted in the developed area of the mining faces in the rock massif unloaded from rock pressure; At the same time as these studies were carried out, additional mine exploration was carried out. On the second, third, and fourth horizons, parallel to the trunk piping mines, the seams are driven by seams 22. The blocks are developed from the center to the south. nitsami. With the simultaneous testing of two blocks, the main central properties

Claims (2)

6 93013 dusts are conducted in the lower unit. When three blocks are simultaneously practiced, said trunks are conducted in the middle block. This method will reduce the time of construction of mines, reduce construction costs and improve the operational reliability of mines. Claim 1. Method for opening and preparation of log coal seams, including dividing a mine floor into blocks, conducting vertical main central and block shafts, cross-sections, trunk field, stratum and rifled workings for treating blocks with clearing holes for rebellion, characterized in , in order to shorten the construction time of mines, reduce construction costs and increase the operational reliability of the mines, first of all they open up a group of blocks located in the fall position, while at least on two horizons, the main central ones. trunks without subsequent utaba and paired block trunks; at the same time prepare the specified group of blocks from the upper to the lower boundaries of the mine floor for further simultaneous development of a group of blocks from the center of the latter to their boundaries, and field main workings are carried out during the period of operation L of the zone unloaded from rock pressure under the worked-out surface of working faces. block boundaries. 2. A method according to claim 1, wherein the main connections are carried out in the lower unit. 3. The method according to Clause 1, das ti and ya yush topics. That main central trunks are conducted in the middle block. Sources of information taken into account when eugpertiz 1.Avtorskoe certificate of the USSR No. 27878, cl. E 21 C 41 / O4, 1966. 2.
