| 摘 要： | 煤矿在井下开采过程中，局部区域的上部各种建筑物和构筑物会受到煤层采空区上覆岩层移动造成地面变形而破坏，因此，留设保护煤柱是常常遇到的一项技术工作。本文应用《垂直剖面法》理论，结合漳平煤矿医院实际圈定了井下保护煤柱边界。

| Abstract: | In the exploitation of underground coal mining, all kinds of buildings and structures in certain region may be destroyed because of the ground＇s distortion caused by the movement of terrane of mine goaf.As a result, to keep the protect ive coal column is always a technical work we have to encountered.In this article, with the theory of ＂the method of vertical section＂ ,and combined with the situation of the hospital of Zhangping colliery, we determined the border of the protect ivecoal column. |
