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

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.
