1) stepped mining technology
台阶式割煤工艺
1.
In order to control the surrounding rock mass stability of fully mechanized large cutting height face in extremely-soft coal-gas burst thick seam effectively,stepped mining technology was presented.
研究表明:台阶式割煤工艺改善了煤壁区域的应力状态,减少了工作面煤壁片帮和端面冒顶的发生不同台阶高度比割煤所引起的围岩破坏程度不同,上下台阶高度比为1∶2时煤壁塑性破坏区最小;极软厚煤层大采高开采煤壁片帮主要以剪切滑移引起的三角斜面片帮为主,超高开采是端面顶板冒落的主因。
