CALCULATION OF THE POWER SUPPLY SCHEME OF THE CLEANING FACE

The treatment area works out a coal seam with a capacity of m = 2.7 m. The development system is long poles in extension, the length of the pole is 960 m. The pole is opened by ventilation and conveyor rods, the ventilation system is direct-flow with a retraction of the outgoing stream of the cleaning face on the conveyor track.

The cleaning face is 150 m long, the ventilation shaft is extinguished during the development of the reservoir, and the conveyor shaft in the spent space, in addition to the main arch support, is supported by an organ row.

Cleaning works are carried out by a cleaning mechanized complex of the type 
2 OPK 70, which includes a mechanized support.  Narrow-grip combine harvester 1GSH68, lava conveyor SUOKP, mobile scraper conveyor SP 202M,  oil station working 2 pcs. and backup 2 pcs.  SNT - 32, pump irrigation unit NMS - 30, lighting installation for lighting the cleaning face and conveyor shaft before pouring on the belt conveyor. The angle of occurrence of the reservoir α = 130 working on the fall, so the installation of a safety winch for the combine is provided  for ZLP.

The power train of the cleaning face is moved to the repair and preparatory shift by a 1LGKNM winch. Delivery of broken coal is carried out by a mobile scraper conveyor SP 202M  and two telescopic belt conveyors 1LT 80 and further along the main belt conveyor on the Bremsberg.

Calculation of the power supply scheme of the cleaning face.

The development system is long pillars along the extension.

The length of the lava is 150 m.

The length of the pillar is 960 m.

The angle of occurrence of the reservoir is 130.

The capacity of the reservoir is 2.7 m.

The distance from lava to the energy train is 40 m.
