摘要
通过矿压观测，总结了综放工作面沿空巷道矿压显现特征．通过数值模拟分析，证明沿空巷道是综放回采巷道的最佳布置方式．采用锚杆注浆技术对鲍店煤矿１３０６综放沿空巷道进行了预加固试验，使巷道顶板下沉量减少８５％～８６％，两帮位移量减少了２４％～４６％．
Based on in situ measurement, the features of ground behavior in a roadway driven along gob of a fully mechanized sub level caving face are summarized. It is verified by the numerical simulation that driving gateway along gob is the best layout for a fully mechanized caving face. Satisfactory results are obtained by bolting and grouting to reinforce gob side of 1306 tailgate in Baodian Colliery. The final amount of side wall convergence reduced by 24%～46%,and roof to floor convergence by 85%～86%.
