矿山大口径排水钻孔的施工工艺探讨

Discussion on Construction Technology of Large Diameter Drainage Drilling in Mines

为了在水害发生第一时间抢救井下人员生命财产安全,就需要在很短的时间将井下突水排出地面。本文主要介绍了西部某矿大口径排水钻孔施工过程以及钻孔成孔后下放大口径套管过程的一些工艺、难题,为以后的大口径钻孔施工积累宝贵经验。

In order to save the lives and property of underground personnel in the first time of water disaster,it is necessary to discharge the underground water inrush from the ground in a very short time.This paper mainly introduces the construction process of large-caliber drainage boreholes in a mine in Western China,as well as some techniques and difficulties in the process of drilling large-caliber casing after drilling,so as to accumulate valuable experience for the future construction of large-caliber boreholes.
