摘　　要：采煤回采至停采线之前,上下巷经常不同步。为了减少煤炭损失,提高回采率,采取新的回采方式,即伪倾斜开采和上巷前进式、下巷前进式回采,使煤炭损失量降低到最小程度,提高了经济效益。After mining to the stopping line, the top tunnel synchronizes with the bottom tunnel. In order to reduce the coal loss and increase the rate of recovery, the new mining methods are adopted, which is false inclination mining, top tunnel outward mining, and bottom tunnel outward mining. The coal loss is reduced as low as the minimum degree. The economic benefit is increased.
