摘要
在伊吗矿实际地质条件和岩石力学性质参数的基础上,研究1-2煤层上行开采的可行性。首先,运用理论分析的方法对1-2煤层上行开采的可行性进行论证,然后,应用数值模拟的方法再现了1-2煤层下行开采时覆岩活动的全过程。通过理论分析和数值分析表明,对1-2煤层上行开采是可行的。
According to the actual condition of geology and character parameter of rock mechanics, the feasibility on upward mining of 1-2 seam of yima mine was studied. Through theoretical analysis, 1-2 mine seam of yima mine was studied in this paper. This article simulates the whole activity of the upper rock of 1-2 seam in its exploitation process by the numerical simulation. Stability factors are obtained, which agree well with achievements.
