基于直接透巷工艺的煤矿地面管道井成井技术研究与应用
Research and application of well completion technology of ground pipeline wells in coal mines based on direct penetrating roadways
摘要
Abstract
In order to solve the problems of high auxiliary workload,high cost,and great safety hazards in connecting roadways and wells in coal mine areas using the"excavating tunnel to locate well"method,as well as the safety hazards of cutting ground borehole pipelines under fire operation underground,an innovative solution of direct penetrating roadway was proposed.The factors affecting safe roadway penetration were analyzed,two-section casing program was optimized,the technical scheme in the penetration state was studied,and the innovative ground pipeline well penetrating roadways technology was formed,transforming"roadway finding well"into"well finding roadway".According to different working conditions,two types of processes,one-time borehole completion and two-time borehole completion,were proposed to solve the problem of different borehole sizes being completed at once,and avoiding underground secondary excavation.The field trial and promotion application of the technology in Huaibei mining area drainage pipeline well demonstrated that two-section casing program pipeline well penetration roadway process technology is safe,reliable,cost-effective,and effectively reduces the auxiliary workload in underground coal mine.The research results provide an important reference for implementing ground pipeline roadways in different mining areas.关键词
