为建立岩层内部的概率积分法参数与地表参数的关系,以相似材料模型为基础,对倾斜煤层开采引起上覆岩层的移动进行了全面的观测研究。根据下沉值与水平移动值获取不同层位的预计参数,分析参数的变化规律,得出用地表预计参数推演岩体内部预测参数的关系式。
In order to establish the relationship between the parameters of probability integration method and the surface parameters in the rock strata, a comprehensive observational study on the movement of the overlying strata caused by the mining of the inclined coal seam was carried out based on the similar material model. According to the subsidence value and horizontal movement value, the expected parameters of different layers are obtained, and the variation rules of the parameters are analyzed. The relationship between the predicted parameters of the rock mass and the predicted parameters of the ground surface is derived.
