综采工作面利用已有巷道收尾停采的研究

Study on Stopping Mining at the End of Existing Roadway in Fully Mechanized Mining Face

山东能源枣矿集团七五煤矿在综采工作面收尾过程中,存在材料、人工投入较多、施工人员劳动强度较大等问题。结合现场实际情况,在3_上213工作面末采前,通过综合分析,将联络巷作为回撤通道,实现了工作面收尾停采降低了成本、提高安全系数和劳动效率、提高煤炭资源的回收率的目标。

There are many problems in the process of the tailing of the fully mechanized mining face in No. 75 Coal Mine of Shandong Energy Zaozhuang Mining Group, such as more materials, more labor input and more labor intensity of the constructors. Combining with the actual situation on the spot, before the end of mining in 3-213 working face, through comprehensive analysis, the connecting lane is used as the withdrawal channel, which achieves the goal of reducing the cost, improving the safety factor and labor efficiency, and improving the recovery rate of coal resources.
