    摘要:

    为了解决煤矿区地面管道井采用“掘巷找井”方式连通巷道与井眼存在的辅助工作量大、成本高,井下切割地面井管道动火作业存在安全隐患等问题,创新提出了地面管道井直接透巷解决方案。通过分析安全透巷过程影响因素,采用优化后的二开透巷井身结构,研究了透巷状态下技术方案,形成了地面管道井直接透巷新型透巷成井技术,变“巷找孔”为“孔找巷”。根据不同工况,提出二开一次成井和二开二次成井两种工艺,解决不同井眼尺寸一次成井的问题,避免井下二次开挖。该技术在淮北矿区排水管道井的现场试验及推广应用表明,二开结构管道透巷井工艺技术安全可靠、节约成本、有效减少煤矿井下辅助工作量,研究成果可对不同矿区地面管道井实施提供重要参考依据。

    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.
