综采工作面充水因素及水害防治

Water Filling factors and Water Hazard Prevention in Fully Mechanized Mining Face

为避免综采工作面水灾事故出现,本文以西铭矿48712工作面复杂地质条件为背景,采用理论分析、现场实践方法对工作面充水因素及防治技术进行了研究,确定48712工作面主要涌水源为相邻48516工作面采空区积水,并对工作面探放水方案进行了设计。根据现场实践结果,经过76天放水,共放水13.5万m3,基本将采空区积水疏排干。

Aiming at flooding accidents in the fully mechanized mining face,taking the complex geological conditions of the 48712 working face in Ximing Colliery as the background,the paper has studied the water filling factors and prevention technologies of the working face on the basis of theoretical analysis and on-site practice methods,determined that the main water source of the 48712 working face is the accumulated water in goaf of the adjacent 48516 working face,and designed the water exploration and drainage scheme for the working face,whose on-site practice results show that after 76 days of water discharge,a total of 135000 m3 of water is discharged,and the accumulated water in the goaf is basically drained.
