大倾角多煤层开采地表移动规律的数值模拟研究

Numerical simulation of ground movement behavior inclined multiple seams mining with deep dip angle

本文是在沈阳煤业集团红菱煤矿大倾角煤层开采实际基础上,通过对国内外关于矿山开采沉陷及防治研究的总结和对研究现状的分析,针对红菱矿倾斜多煤层开采的采矿地质条件,采用数值模拟的方法,对矿区煤层开采引起的岩体移动和地表沉陷的基本规律进行了研究。所得结果对现场开采及地表沉陷治理具有一定的指导作用,对于同类地质和开采条件的矿区具有参考价值。

On the foundation of hongling mining practice, according to the complex mining and geological conditions of deep excavation in hongling mine, numerical simulation is carried out for studying on the rule of strata movement and surface subsidence due to coal extraction in hongling mining district. The results are of tutorial impact for practical mining and governing of subsidence hazards
