计算储量时,求块段煤层倾角平均值的计算程序较为烦琐。尤其是南方几省的煤矿床,构造复杂,煤层变化频繁,投影到图上的煤层等高线间距忽宽忽窄。要求出一个块段内的煤层倾角平均值,需选择几条倾斜方位线,逐个量取等高线水平宽,计算出平均倾角,最后翻表查出函数 When calculating reserves, it is more cumbersome to find the average coal seam dip angle calculation procedure. In particular, the coal deposits in several provinces in the south are complicated in structure and frequently change in the coal seam. The spacing of contour lines projected onto the coal seam is suddenly wide and narrow. To find out the average coal seam dip within a block, select several inclined azimuth lines, one by one to take the contour line horizontal width, calculate the average tilt angle, and finally turn the table to find out the function
