摘　　要：为了实现显德汪矿1614大倾角不规则工作面的安全回采,在分析工作面开采特点的基础上,重点对支架稳定性及扇形回采工艺进行了研究。研究表明,通过采取提高支架初撑力,增大支架与顶底板摩擦系数等措施可以提高支架的稳定性,同时加强扇形区域调采期间及老巷附近的顶板控制,最终实现了1614工作面的安全回采,可为类似条件下的工作面回采提供借鉴。In order to realize safe recovery mining of 1614 large and complex inclined angle working face in Xiandewang Mine,based on the mining working face features,support stability and fan-shaped mining technology was studied.The result showed that measures that improving the initial support force,increasing friction coefficient between support and top and bottom plate and the roof control of sector condition and old roadway,finally realized the safe recovery mining of 1614 working face,providing reference for working face under similar condition.
