矿区三下开采安全性评价与计算机仿真方法

Safety assessment and method of computer simulation on mining under "three bodies"

近年来建筑物下、水体下、公路、铁路下煤层安全开采问题凸显,针对这一问题,进行了开采损害的复杂性、多样性、不确定性分析,并以"开采方案-覆岩移动变形-地表损害程度-建筑设施及环境保护"为主线,以概率积分法为基本理论,以计算机仿真为手段,建立矿区地面保护物下安全开采的评价体系,并在西部矿区进行了广泛的实践,实践证明这种评价体系适用性强,它不仅是矿区地面保护物下安全开采的可靠方法之一,也是矿业可持续发展的一种有效的方法。

Based on math model analysis and computer simulation, the paper analyses the complexity of mining harm and constructs the assessment system of safety mining under buildings. Practice has shown that the assessment system is a reliable mean in mining under buildings.
