新时期沿空留巷技术应用于煤矿开采中的作用

Application of Gob-side Entry Retaining Technology in Coal Mining in the New Period

在进行煤炭开采作业时,会留存部分区域不进行开采作业,以便于执行矿井内的空气流通、水的排放和瓦斯的提取等工作,通过这种方式来增进开采作业的效率。本文介绍了某煤矿开采区域的位置及变形情况,同时详细分析了其地质水文信息,对沿空留巷技术实际应用中的方案设计工作、巷旁巷内支护作业及瓦斯防治等环节开展情况进行了研究,发现使用该技术可以显著提升煤矿作业区域的通风效果,提高煤矿资源的回收率,并极大地降低开采成本。

During coal mining operations,some areas will be left untouched to facilitate air circulation,water discharge,and gas extraction within the mine,thereby improving the efficiency of mining operations.This article introduces the location and deformation of a coal mining area,and analyzes its geological and hydrological information in detail.It studies the practical application of the goaf retention technology in the design of the scheme,support operations in the side and inside of the roadway,and gas prevention and control.It is found that the use of this technology can significantly improve the ventilation effect of the coal mining operation area,increase the recovery rate of coal mining resources,and greatly reduce mining costs.
