| 摘 要： | 煤层倾斜时，各开采单元随采深变化，其地面不同点对应的开采影响面积可以用边界角圈定，本文针对圆锥和方域两种不同的假定，导出了影响函数的两种不同形式，并给出了下沉计算在直角坐标系统内的解析表达式，这样，影响函数可在计算机上进行计算，从而减少了计算和作图的工作量。

| Abstract: | Under the condition of inclined coal seam, the critical area which influenced by the wining operation, ingcorresponding to the different points on the surface of each mining unit with the change of mining depth, can be defined by the angle of draw.In connection with the two assumptions of the circular area and square area,two different forms of influence function are derived and an analytical expression for the subsidence calculation within a right angle coordination system is given in the paper, thus facilitating the calculation of the influence function with a computer and reducing the amount of work of calculation and graphing. |
