反井钻机与人工正向扩刷在煤仓施工中的应用

Application of Hole Drill and Artificial Positive Brush Technique in Construction of Bottom Coal Bunker

以挖金湾煤业公司4#煤层井底煤仓施工为对象,通过施工方案的对比分析和工艺优化,确定采用反井钻机与人工正向扩刷施工技术,实现了井底煤仓高效、快速施工,使工期由2个月缩短至45 d,对类似工程的施工具有一定的借鉴作用。

Taking Wajinwan coal company 4# coal seam bottom construction as an object, through the contrastive analysis of the construction scheme and process optimization, determination by the well drilling rig and artificial positive brush construction technology, and realized the bottom coal efficient, rapid construction, shorten the period of 2 months to 45 days, has a strong reference to the construction of similar projects.
