张集煤矿地面区域治理水平分支孔钻效分析及提速对策

Drilling efficiency analysis and drilling speed-up measures for surface lateral drilling for regional treatment of water hazards in Zhangji Coalmine

摘要:

地面区域治理技术在淮南矿区水害治理上效果显著，对目的层进行水害治理是矿井采掘工作面生产推进的前提。水平分支孔快速施工是区域治理技术实施的关键，本文通过对张集煤矿区域治理水平分支孔综合钻效、生产钻效、纯钻进效率、剔除低效钻进效率4种钻效指标进行统计分析，得出工艺技术水平、生产管理水平、组织管理水平对钻效的影响，并提出提高钻效的对策。

Abstract:

The surface regional treatment technology has a remarkable effect on the water disaster control in Huainan mining area. The water disaster control of the target layer is the premise of pushing forward the mining face， in addition， the fast construction of horizontal branch hole is the key to the implementation of regional governance. This article statistically analyzed four kinds of drilling efficiency index of comprehensive regional governance in Zhangji coal mine including drilling efficiency of horizontal branch hole， production drilling efficiency， pure drilling efficiency and elimination of drilling inefficiency. As a result， the drilling efficiency is affected by technology， production management， organization management levels， and some countermeasures to improve drilling efficiency are put forward.
