矿井“三量”即指开拓煤量、准备煤量及回采煤量。为了研究瓦斯抽放对矿井“三量”可采期的优化作用,以鹤壁矿区所属矿井为实例,在对目前生产接替中存在的主要问题分析的基础上,就瓦斯预抽对“三量”可采期的影响进行专门研究,主要通过实施瓦斯的综合抽放和编制合理的采掘接替计划来保证回采工作面的安全生产,最终制定出合理的适合鹤壁矿区生产实际的“三量”关系。
Mine “three amount ” refers to open up coal, coal preparation and recovery of coal. In order to study the optimization effect of gas drainage on the “three-volume” recoverable period of mine, taking the mines in Hebi mining area as an example, on the basis of the analysis of the main problems existing in the current production succession, Three-volume “recoverable period of the impact of specialized research, mainly through the implementation of gas drainage and the preparation of a reasonable plan to ensure the succession of mining succession mining face safety production, and ultimately develop a reasonable Hebi mine production actual Three amount ”relationship.
