摘要
本文以丁集煤矿瓦斯抽排放井工程施工实例,介绍了大口径瓦斯抽排井钻孔结构设计依据、钻井工艺方法、设备机具配套、钻井技术参数、泥浆工艺、下管方法及固井工艺等,总结了其技术效果。
The paper describes the criteria for design of the structure of large-diameter gas drainage boreholes,boring technology,matching of equipment and tools,well drilling technical parameters,mud technology,method for lowering pipes,cementation process,etc.by using gas drainage well construction project in Dingji coal mine as an example.It also summarizes the technical results of the project.
