【摘要】：分析了急倾斜煤层开采岩层和地表移动特点,总结了急倾斜煤层开采地表下沉盆地的4种类型,并对这4种下沉盆地的形成原因进行揭示。给出了急倾斜煤层开采沉陷预计建模的4条原则,并针对该原则提出了一种基于概率积分法的急倾斜煤层开采沉陷预计模型,该模型能清楚地解释急倾斜煤层开采煤层顶底板岩层移动和地表下沉的相互关系。建立了预计方法的坐标系,分析了预计参数的物理意义,并给出了预计参数的变化规律。编制了基于本文方法的计算机程序,并利用矿区观测站实测数据对本方法进行了验证。实验结果表明,本文方法对于倾角大于70°的急倾斜煤层开采沉陷预计效果较好,能为矿区的环境保护,地表移动预警起到决策支持作用。
[Abstract]:The analysis of steep coal seam mining strata and surface movement characteristics, summarizes the 4 types of surface subsidence basin in steep coal seam mining, and the 4 of the basin subsidence causes are revealed. Given the steep expected 4 principles of modeling of coal mining subsidence, and the principle is proposed based on the tilt is expected model of coal mining subsidence emergency probability integral method, the model can clearly explain the relationship between steeply inclined coal seam mining coal seam roof and floor strata movement and surface subsidence was established. The predicting method of coordinate system, analyzes the physical meaning of expected parameters, and gives the parameters estimates. A computer program is compiled in this paper method based on the verification of this method and use of mining data of observation station. The experimental results show that this method is greater than 70 degrees for the angle of steep coal seam mining subsidence forecasting The effect is good, it can protect the environment of the mining area, and the ground movement early warning plays the role of decision support.
