The invention relates to the mining industry and is intended for the development of gentle coal seams.

The known method of developing horizontal, flat and sloping coal seams with long pillars in the fall, rising or strike by double lavas, moreover, in the space developed, following the advancement of the faces, two-lavas raise the output for issuing the outgoing jet 1.

However, this method is not effective enough.

A known method for developing flat coal seams during panel preparation of a mine floor, including panel and brown drifts, main ventilation drift, inclined field workings and cleaning works within the panel in one direction from its borders with lavas passing from inclined workings 2.

However, the known method is characterized by insufficient development efficiency.

The purpose of the invention is to increase the development efficiency by reducing the time to prepare the panel, reducing the cost of carrying out and repairing field workings, increasing the concentration of cleaning and preparatory work.

The goal is achieved by the fact that according to the method of developing flat coal seams during panel preparation of the shallow floor, including panel and brown drifts, the main ventilation drift, inclined field workings and cleaning work within the panel in one direction from its borders with lavas passing from inclined openings, the panel is divided in portions along the way by connecting the brown drifts with oblique formations, cleaning works are carried out with the location within each river and On one lava, when the lava passes into the adjacent area, the lava of the overlying adjacent trench is placed in front of the formation oblique excavation limiting this area, the inclined field excavations are carried out after passing each izva lava, knocking the main ventilation drift with brown drifts, which support from the underlying rus, and after the transition of lava

in the adjacent area on the brown drifts establish a jumper between inclined field and reservoir workings, and reservoir inclined workings repay.

5 The method is carried out as follows.

The mine field is opened by the central trunks on the main horizon, the flanking trunks on the ventilation horizon and is divided into two bilateral panels (bremsbergovaya and inclined) with the location in the center of the bremsbrags and slopes. In the upper part of the panel, the main ventilation drift is conducted, and the brown drifts, when conducting, are connected by sheet-shaped workings, which delimit the panel into sections according to the number of designed lavas.

On the flanks of the panel, the reservoir inclined openings are retained to release the outgoing air stream, connected to the flank

ventilation trunks

through which fresh air is supplied from the center of the panel to the lava of each Rus.

The number of contoured pillars with colorful drifts is constantly more than the number of workers worked by no less than one. This ensures the separation of separate airing and transport from cleaning faces during the bottoming of the brown drifts during the preparation of the next extraction column.

0 The main vent shchrek is connected after the passage of lavas with brown drifts maintained at the boundary of the massif — the developed space, by inclined field workings for the discharge of outgoing jets. Inclined field workings

5 are located in the unloaded zone with a stabilized displacement of rocks at a distance from inclined reservoir openings sufficient to position sluice bridges between them in a brown

0 drift

Clearing works with the redemption of inclined reservoir workings are conducted from the edges of the panel by lavas, positioning them within each Russ and the site one by one so that when lava passes into the adjacent site, the lava of the overlying adjacent Rusa lies ahead beyond the boundary of this site, and the inclined field development and The connection with the fairway in this area should be completed.
