摘要
概率积分法是预测煤矿采空区产生地面移动最直接,最简单的方法之一,应用广泛。但该方法的应用条件非常苛刻,对于地层复杂的地区,预测精度不高。本文为预测出多煤组开采造成的地面破坏,将概率积分法与空间分析软件相结合,运用GMS软件的空间分析功能和概率积分法的理论基础,对采空区产生的地面破坏进行预测。将这种方法运用到塔妥煤矿中,得到了当该煤矿的四个煤组完全开采时产生的地面破坏预测,其计算结果比直接运用概率积分法更加接近实际。
Probability-integral method is the most direct and easiest way to forecast the surface movement produced by goaf of the coal mine. But the application condition of this method is very rigor, for the complex layer area, the forecasting accuracy is not grate. To forecast the surface destruction made by some coal groups, this article connects the Probability-integral method with spatial analysis software, using the spatial analysis function of GMS software and the theory of Probability-integral method. Taking the Tatuo Coal Mine for example, the result of this method is more practical than the result of Probability-integral method.
