摘　　要：某煤矿在勘测了自身的回采率以及自身地质条件后,针对42103回采工艺的更换问题,全面研究了两项回采工艺(即一次采全高回采工艺和放顶煤回采工艺)的应用原则,在工程参考方面,给具有类似地质条件的不同矿井的开采提供了参考依据。After surveying the recovery rate and geological conditions of a coal mine, aiming at the replacement of 42103 recovery process, the application principles of two recovery processes (i.e. one full height recovery process and top coal caving recovery process) were comprehensively studied. In the aspect of engineering reference, it provides a reference for the mining of different mines with similar geological conditions.
