简化位错模型结合蒙特卡罗法反演煤矿塌陷机理

Inversion of Coal Mine Subsidence Mechanism Based on Simple Dislocation Model Combined with Monte Carlo Method

以位错理论模型为基础,根据塌陷的特点和煤矿开挖的实际情况建立适合煤矿塌陷机理的简化位错模型。利用水准观测数据,将蒙特卡罗非线性反演算法与简化位错模型结合起来对江西省某煤矿工作面开采导致的地表塌陷进行了反演解释。反演结果表明得到的塌陷趋势量和常规监测数据基本吻合。

On the basis of dislocation model,a simple rectangular dislocation model that is suitable for coal mine sub- sidence mechanism is established according to the characteristics of coal mine subsidence and the actual situation of the coal mine excavation. Monte Carlo method joints simple dislocation model to explain the subsidence of the work face in the one of coal mine of Jiang Xi province by using the data of level observation. The results of inversion show that the trend of the inversion closely fits the routine monitoring data.
