摘要
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 change rule of the destruction of surface structure, in this paper, probabilistic integration method and distance power inverse ratio method are used to calculate various deformation values of the ground surface after repeated mining of multi - face. The method of rectangular grid model is used to visualize the calculated results in order to draw out the defomaation contour. The calculation method is applied to the actual production of Xima Coal Mine, and the results obtained by the method of drawing the deformation contour line are compared with the field measurement results, which shows that the error between them is small, which meets the practical needs of the mining engineering field.
