井下高压突水钻孔引流注浆封孔方法研究
|
摘要
为了彻底消除塔然高勒煤矿主井冻结孔高压水水害危险,在揭露的高压突水钻孔旁施工向下倾斜的与其连通的引流孔进行引流泄压,引流孔内安装引流管和第1注浆管,引流孔下方填充有利于封堵高压突水钻孔的矿渣层,内插设有第2注浆管,在对引流管和矿渣进行注浆加固后,利用引流管对高压突水钻孔采用升压注浆的方法进行封堵。研究结果表明:对高压突水钻孔通过采用引流泄压后升压注浆封堵方法,将失控的高压突水钻孔转化为可控钻孔,有效地减少了工作量,提供了有利的施工条件,改善了注浆封堵效果,从而提高了封孔效率、封孔可操作性、封孔安全性和封孔可靠性,同时为孔口防突措施失效的钻孔处理提供一种可行的处理思路。
In order to thoroughly eliminate the danger of high-pressure water and water hazard in the freezing hole of the main shaft of Tarangaole Coal Mine,the downward inclined drainage holes that were connected with them were constructed beside the exposed high-pressure water inrush boreholes for drainage and pressure relief.Drainage pipes and first grouting pipes were installed in the drainage holes.The slag layer beneath the drainage holes was filled to block the high-pressure water inrush drilling holes,and the second grouting pipe was inserted therein.After the drainage pipe and slag were grouted and reinforced,the drainage pipe was used to plug the high-pressure water inrush borehole by boosting grouting.The research results show that the high pressure water inrush drilling hole converts the uncontrolled high pressure water inrush into a controllable drilling hole by adopting the pressure-relieving pressure-injection plugging method after drainage and pressure relief,which effectively reduces the workload and provides favorable construction conditions.This improves the effect of grouting plugging,thereby promoting the efficiency,sealing operability,sealing safety and reliability.At the same time,it also provides a feasible way to deal with the failure of borehole anti-burst measures.
