摘　　要：轩岗矿区地处宁武—静乐向斜北东翼边缘仰起端,与恒山隆起带相接,地质构造较为复杂,统计分析区内太原组可采煤层回采率较低,究其原因认为,受区域地质应力场控制,异常发育的断裂构造和5#煤层塑性流变是影响正常开采和回收率的主要地质因素,落后的采煤方法和资源监管制度不健全是导致资源严重浪费的次要因素。建议加强矿井地质预测预报工作,选择与煤层赋存条件相适应的采煤方法,以有效提高煤炭资源回收率。The Xuangang mining area is located at the northeast limb chin up end of the Ningwu-Jingle syncline and connected with the Hengshan uplift zone, and rather complex in geological structure. According to statistics, the recovery rate of mineable coal seams in the Taiyuan Formation is low, considered the reason is because of controlled by regional stress field, well developed fracturing structures and No.5 coal seam plastic rheological behavior are main geological factors to impact normal mining and recovery rate. Backward mining method and unhealthy resource monitoring system are the secondary causes to cause serious waste of resources. It is advised that to strengthen coalmine geological prediction and forecasting works,to select mining methods compatible to coal seam hosting conditions to improve coal resources recovery rate effectively.
