本文分析了寺河矿开采工艺,并论述了工作面回采中残留煤柱的赋存情况。在此基础上根据现场实际情况,研究了几种残留煤柱的开采方法,即内错尾巷回收煤柱技术、无煤柱开采技术、短壁开采技术。对以上技术进行了深入分析,并作为今后煤炭开采残留煤柱开采方法。 This paper analyzes the mining process of Sihe Mine and discusses the occurrence of residual pillars in face mining. On this basis, according to the actual situation in the field, several methods of mining residual coal pillar were studied, namely the coal pillar recovery technology within the wrong end lane, non-pillar mining technology and shortwall mining technology. In-depth analysis of the above technology, and as a coal mining residual coal pillar mining methods.
