摘要
华北型煤田煤层底板突水灾害性评价是一种特殊的工程地质问题 ,目前已有数学 ,力学和经验的多种方法研究这一问题 ,但是用岩体分级的方法进行安全性评价的尚未见报道。本文建立了一套新型的岩体分级方法 ,并将该方法用于刘桥二矿 6 5 1工作面底板突水评价 ,收到了很好的效果。
It is a special engineering subject to evaluate coal floor stability of North China type coal mines. Although there are many methods for this problem, few articles discuss the approaches of rock classification to control coal floor water inrush. In this paper, a new geomechanial classification system is given out, and it was successfully applied to coal floor evaluation of working face 651 in Liuqiao Coal Mine. The method is also suitable to other North China type coal mines.
