短壁连采工艺在回收边角煤资源中的应用研究

Application Research on Short-Wall Continuous Mining Method in Recycling Leftover Coal

为了提高资源回收率,提出将短壁连采工艺应用于解放边角煤呆滞煤量的生产实践中。通过采用理论分析、数值模拟和工程实测相结合的研究方法,结合某矿边角煤赋存地质条件,对短壁采场的矿压显现和顶板运动规律进行分析研究,得出采取适合的顶板控制措施实现对坚硬顶板的有效控制是短壁连采工艺实现安全回采的关键。

In order to improve resource recovery,put forward that short-wall continuous mining methods should be shipped to production practice of mining leftover coal. By theoretical analysis, numerical simulation and engineering practice, combined with geological hosting conditions of a mine＇s leftover coa, analyzed the underground pressure behavior and roof movement laws, obtained that the key to safely mining is take appropriate measures to control the hard roof.
