摘　　要：以长平煤矿4321工作面地质条件为背景,分析了采用充填技术过横川开采技术的优点,设计了4321工作面过空巷的开采技术方案,并对充填材料、充填设备以及技术工艺进行了设计。矿压监测结果表明,随着工作面与横川的距离减小,液压支架工作阻力逐步增大,但未超过额定值。工作面回采期间未出现片帮冒顶现象,保证了工作面的正常回采。Based on the geological conditions of the 4321 working face in Changping Colliery,this article analyzes the advantages of using filling technology to cross the Hengchuan,designs a mining technology scheme for the 4321 working face crossing abandoned roadway,and designs the filling materials,filling equipment,and technical process,whose monitoring results indicate that as the distance between the working face and Hengchuan decreases,the working resistance of the hydraulic support gradually increases,but does not exceed the rated value.During the mining process of the working face,there was no occurrence of rib spalling,and ensures the normal mining of the working face.

关 键 词：综采工作面 过空巷 全部充填法 支架工作阻力
