摘　　要：本文在分析了传统长壁式崩落法缺点的基础上 ,提出了一种新的回采方法———人工底柱长壁式崩落法。该方法减少了采准工程量 5 0 % ,减轻了工人劳动强度 ,实现了单平巷采准、单上山切割。经长期的开采实践证明 。Based on analysing the shortcomings of traditional longwall caving,this paper presents a new stoping method-longwall caving with artificial bottom pillars.In this method,developed amount is decreased by 50%;labour in tensity is lightened;single adit development and single rise cutting are realized.Long term mining practice proved that the method is a good one for gentle inclined thin seam.
