摘要

Procedure for the exploitation of coal in a semi-steep and steep deposit in inclined extraction, using as a profit instrument a brush that, by means of a driven chain, that runs on chain sprockets of a driving place, respectively of inversion, sliding in the direction of the advance of the extraction, moves along the extraction contact, after several cuts of benefits obtains a convex course, characterized in that after reaching a predetermined convexity of the extraction contact, one of the driving places, respectively is reversed and then the brushing process is carried out with subsequently tensioned chain and renewed advance by sections of the place made to back off of drive, respectively of investment, of the planer chain until the convexity is removed again essentially, respectively extraction contact is again rectified.
