摘要
围岩裂隙水通过钻孔进入抽采管路,对抽采效果造成影响.为解决该问题,通过对底板抽放巷围岩裂隙水的涌水量和出水点的分析,采取放水钻孔及钻孔工艺减少钻孔水量;针对管路积水不断优化放水器,有效解决了抽放管路积水问题.提高了抽采效果,为工作面的抽采达标发挥了积极作用,同时为发电机组提供更加稳定的气源,增加了矿井发电量实现经济效益.
Abstract
Surrounding rock fissure water enters the pumping pipeline through the borehole,which affects the pumping effect.In order to solve this problem,through the analysis of the water inflow and the water outlet point of the surrounding rock fissure water of the floor drainage roadway,the water discharge borehole and the drilling technology are adopted to reduce the water quantity of the borehole,the utility model effectively solves the problem of water accumulation in the pumping pipeline.It improves the effect of pumping,plays a positive role in reaching the standard of the working face,provides more stable gas source for the electric generator,and increases the mine power output to realize economic benefits.
