摘要
南阳坡煤矿8703工作面在煤炭开采过程中出现顶板不垮落现象,经现场研究,采用注水软化技术对顶板进行软化处理,消除了煤炭开采过程中的安全隐患,带来了重要的社会效益,为类似工程提供了一定的借鉴。
The roof of 8703 working face in Nanyangpo Coal Mine can not collapse in the process of coal mining.After field research,the roof was softened by water injection softening technology,which eliminates the hidden danger of safety in the process of coal mining,brings important social benefits,and provides a certain reference for similar projects.
