矿井防水

矿井边界防水煤柱管理技术研究

Management Technology Study of Water-Proof Coal Pillar of Mining Border

对于受水害威胁的矿井，防水闸墙是井下防水的主要安全设施。

The water proof gate is the main safety facility against underground water to the coal mine threatened by water disaster .

为了防止煤矿井下透水事故的发生，对五阳矿井下防水工程进行了一系列设计和施工，并作了防水闸的压力试验，取得了良好的效果。

In order to prevent water burst , a serious of waterproof project were carried out in Wuyang mine , which included waterproof gates and achieved good result .

通过对百善煤矿松散含水层下合理煤岩柱高度进行研究分析，为该矿和条件类似矿井缩小防水煤柱、提高上限采煤提供了可靠的依据。

By means of the study and analysis of rational coal and rock pillars height under the loose water-bearing strata of Baishan Coalmine , the reliable basis is provided for reducing the water-bearing barrier and enhancing the upper limit for coal mining in Baishan Coalmine and other similar coalmines .
