Disclosed is a method for driving of working by cutting-through the worked-out area by longwall method, wherein the working is driven simultaneously with the working face. The driving of working is carried out in two steps: first a cut-through is formed behind the niche over the seam, this is protected with yielding pillar at one side and with man-made strip at the other one, and at the second step the working is driven with delay compared to the working face at distance, at that destroyed rocks in worked-out area are enough compacted. |
