在顿巴斯中心区,由于开采深度加大要采用岩石开拓。这种传统方式的特点是在用风镐和采掘机时在运输平巷和淄煤眼中掘进。开采作业向下部水平过渡时,不采用这种岩层运输平巷和淄煤眼,而是沿煤层重新掘进通风平巷。在这种情况下,在开采区上部当下带状煤柱。 In the center of Donbass, rock exploitation is required due to the increased exploitation. A characteristic of this traditional approach is the tunneling and Zibo coal tunneling with picks and mining machines. Mining operations to the lower part of the level of transition, do not use this rock transport lanes and Zi coal eyes, but along the seam to re-excavation ventilation Lane. In this case, the current ribbon pillars in the upper part of the mining area.
