摘　　要：为掌握工作面范围内地质构造特征,结合巷道揭露和三维地震探测数据,应用坑透方法查明了张集煤矿1712(6)工作面回采范围内地质异常区分布特征。结合1712(6)工作面开采技术参数,基于工程地质评估分析,开展了上提段覆岩运移特征预测、顶板围岩稳定性分类及控制技术分析,根据分析结果确定了综采主要设备,提出了工作面过地质异常区和提高回采上限阶段时围岩稳定性控制技术,实现了工作面的安全高效开采。For mastering geological features of mining face, distribution characteristics of geological abnormity in 1712 （6） mining face of Zhangji Coal Mine were discovered by tunnel perspective method according to roadway expose and three-dimensional seismic data. Combined with mining technology parameters of 1712（6） mining face and based on engineering geology investigation, movement behaviours prediction of overlying strata was carried out, as well as classification and control technique of stability in surrounding rock. The major mining equipments were determined based on a- nalysis results. And the surrounding rock stability control technologies in geological abnormity and raising upper limit of mining were proposed, which realized the safe and efficient mining.
