摘　　要：针对斜沟矿18112大采高超长工作面回采中的片帮治理难题,在现场观测的基础上,详细分析片帮的原因、特点;通过采取局部注浆、超前静压注水、降低推进速度、加强工作面管理等措施,实现了大采高超长工作面片帮的有效控制;可为类似条件下的工作面安全回采提供参考。By analysis of the cause and characteristics of rib spalling during mining at 18112 super-long working face with large mining-height in Xiegou Colliery,the paper presents the measures of local grouting,advanced static pressure water injection,reducing advance speed and reinforcing the management of working face,which can control the rib spalling effectively and provide a reference for safety mining at working face with similar conditions.
