摘要:
概率积分法是目前煤矿开采中应用最多的地表移动预计方法。对于山区浅埋煤层开采而言,由于地表地形和地层分布等因素的影响,地表的下沉、倾斜、曲率、水平移动等特性与平原地区有很大不同。文中对概率积分法预计公式做了适当修改,并编制了MATLAB拟合程序,实现了多参数表达式的非线性曲线拟合。实测数据拟合结果表明,修改后的预计公式应用效果良好。通过拟合所得的表达式,反求取了山区浅埋煤层地表移动的主要参数,由此求得的地表移动参数符合实际,可靠性高。
Abstract:
Probability integral method is most widely used in current coal mining method for prediction of surface movement for shallow coal seam mining in mountainous area. Due to terrain and stratum distribution factors,the subsidence, tilt, curvature, horizontal movement and horizontal deformation characteristics are very different from plain areas.In this paper, the probability integral method formula is expected to do the proper modification and preparation of the MATLAB fitting procedure,realizing more parameters expression of the nonlinear curve fitting. The measured data fitting results show that the formula is expected to change its application with a good effect. By the expressions of fitting, calculating the surface movement parameters with the shallow coal seam in mountainous area. This surface movement parameters accord with the actual and have high reliability.
