摘要
掘进工作面巷道的支护方式直接影响该巷道的支护质量及服务年限,对保障煤矿的安全生产具有重要的意义。本文就层间距变化较大条件下的支护技术在西铭矿的应用进行了分析,在支护技术和方式上进行了改进,提出防止措施,为解决层间距不稳定状态下的支护技术开辟了一条新途径。
The supporting method of driving face directly affect supporting quality and service life of this face,has vital significance for ensuring coal mine safety in production.This paper analyzes the application of supporting technology under the condition of spacing layer larger changes in Ximing coal mine,in supporting technology and methods is improved,puts forward the prevention measures,and opens up a new way to solve the support technology under layer span unsteady state.
