| 摘 要： | 对瓦斯隧道煤层建立了三维空间坐标，根据超前探测或预测孔，运用三角函数计算，确定了实际煤层的空间位置，并与试验情况和施工揭示情况进行对比，发现三角函数在确定瓦斯隧道煤层空间位置有较好的适用性。

| Abstract: | The three dimension spatial coordinate of gas tunnel coal layer was built,according to advanced detection and predicated core,with circular function calculation,the spatial site of practical coal layer was determined,which was compared with experimental situation and construction disclosed situation,it found that the circular function had better applicability in determining gas tunnel coal layer spatial site. |
