摘　　要：根据国家节能减排要求,针对柳湾煤矿J1107综采放顶煤工作面初采丢煤端头丢煤、停采丢煤、浮煤丢煤等的情况,分别计算丢煤量,并采取了控制放顶煤损失、优化放煤工艺、改进放煤设备及加强组织管理等技术措施,有效地提高了回采率。According to the national requirements of energy conservation and emission reduction,the paper introduces the calculation of coal loss at the initial mining end,the stoping coal loss and the floating coal loss at J1107 fully-mechanized caving face of Liuwan Colliery,and presents the technical measures such as controlling the loss in top coal caving,optimizing the caving process,improving the caving equipment and strengthening the organization management to effectively improve the recovery rate.

关 键 词：放顶煤回采 丢煤量计算 提高回采率措施
