安全破除井下密闭墙的几种方案

Several Schemes for Safe Breaking Down the Sealing Wall of Underground Mines

排放瓦斯是矿山救护队经常接触的一项技术工作,其中有很多极其危险的因素,特别是破除井下密闭墙料石闭,既费时又费力,而且危险性大。本文结合救护工作的实际,阐述了安全破除井下密闭墙的几种方法,同时探索性地提出了用高压水流切割技术"水刀"的破闭方案,为井下破闭工作提供了技术性参考。

Gas drainage is a technical work frequently conducted by mine rescue teams,where there aremany extremely dangerous factors,especially to break down the sealing wall,which is time-consuming,laborious and dangerous.Combined with the practical rescue work,several schemes for breaking down the sealingwall are expatiated in this paper.At the same time,a scheme of water knife,high pressure water flow cutting technique,is exploringly proposed,which provides technical references for breaking down the sealing wall.
