SU1666719A1 - Opening and preparation method for gently dipping coal seam - Google Patents

Abstract

The invention relates to the mining industry. The goal is to reduce material costs during the construction of the mine. The mine field is opened by the central trunks (C) and the paired main and auxiliary flank C located on each of its flank. At the same time, unloading lava (RL) is worked out from the central and flank C during the construction of the mine. In the unloaded zone of the developed area of the RL, trunk workings (B) are conducted. The rock from conduction B is placed in the developed space of the X-ray laser. Extraction of coal extracted from X-ray and passing of mountain B is carried out separately through each pair of central and flanking C. 2 Il.

WITH

The invention relates to the mining industry and is intended to open and prepare flat coal seams, incl. occurring at great depths.

The purpose of the invention is to reduce material costs during the construction of the mine.

Fig. 1 shows a scheme for carrying out the method during the construction of the mine; figure 2 - diagram of mining at the time of commissioning of the mine.

The method is carried out as follows.

In a mined field divided into blocks, for example, two central blocks are prepared for initial mining, which are located in the fall position. On the boundary between the blocks, the central trunks of the upper and lower boundaries pass.

The mine floor is flanked by twin main and auxiliary trunks 2.

After the construction of the shafts, near-barrel yards and open formation during the construction of the mine, unloading lavas 3, 4 and 5 are cut into the drainage, main and ventilation horizons for work along the mine floor, and after them in the zone unloaded from the mountain pressure the main valves are conducted 6, main 7 and 8 drainage drifts. Unloading lava 9 is cut into the drainage horizon for rebellion work, followed by slopes 10, and unloading lava 11 and bremsbergi 12

The development of all discharge lavas are at the same time. Coal of mining is produced from the mine through the central 1 and flanking main 2 trunks with cage

rises from the surface and transported to the main platform of the mine. Airing of the workings is carried out separately through each pair of trunks.

A breed of 6 tons of drifts, inclinations, and Bremsberg is laid in the developed space of the corresponding discharge lavas.

As lavas 3, 4 and 5 are advanced, the side openings 13 are made, by means of which clearing faces are prepared for working in a constant pattern with lavas during the uprising.

Claims (1)

The invention method of opening and preparation of flat coal seam, including opening C 1 it   I, .9 eight 1 0 five the mine floor by the central trunks and the main flank trunk on each flank, working off the discharge lavas, carrying out with the breaking of the rock the main workings in the unloaded zone of the open space of the said lavas, which is characterized by the fact that. in order to reduce material costs during the construction of the mine, an additional flanking shaft is additionally effected on each flank, after which the discharge lavas are worked out simultaneously during the construction of the shaft from the central and flanking shafts with the main workings, and the broken rock is placed in the developed space of the discharge lavas. 6
