为研究井下多工作面重复采动后地表变形等值线的变化规律,采用概率积分法和距离幂次反比法,对井下多工作面开采后的地表各个变形值进行计算,应用矩形网格模型的方法,将计算的结果进行可视化处理,绘制出重复采动地表各个变形等值线.将该计算方法应用到西马煤矿的生产实践当中,将上述各变形值等值线绘制方法得到的结果与现场实测结果进行对比,可见二者的误差较小,符合采矿工程领域实际需要.
In order to study the variation law of surface deformation contours after repeated mining in underground mine face, the deformation of underground multifaceted mining face is calculated by probability integral method and distance power inverse ratio method. The rectangular grid model , The results of the calculation are visualized and the contour of each deformation of the mining surface is drawn.Application of this calculation method to the production practice of the coal mine in Xi Ma results in the above drawing of the deformation value isoline Compared with the field measured results, we can see the error between the two is small, in line with the actual needs of the field of mining engineering.
