摘　　要：断层防水煤柱的留设是从事水文地质工作者经常遇到的一项基础水文工作。峰峰集团在2009年更换了其断层防水煤柱留设的计算公式,水文技术人员对新公式的理解存在偏差,出现计算留设煤柱不正确的现象。针对这一问题,从新的计算公式入手,对各断层防水煤柱常用公式进行分析,探讨如何正确计算留设断层防水煤柱,并提出了在应用防水煤柱公式计算时需要注意的问题,为水文地质工作人员提供参考。Fault water- proof setting is fundamental to hydrology geology work. Fengfeng Group changed the fault water- proof setting formula, technical staff had wrong understanding of it, the calculation result of coal pillar was incorrect.Based on this problem, the common formula of all fault water- proof setting was analyzed form the new formula, the correct calculation was discussed, and the attention during the calculation was given, which provided reference for hydrogeology staff.
