综采工作面顺槽破碎带注浆加固技术应用

Application of grouting reinforcement technology in the fracture zone along Channel in fully mechanized mining face

针对麻家梁矿综采工作面地质条件,对工作面顺槽破碎带提前进行注浆加固,采取了合理的注浆方案并对治理效果进行了监测分析,既减少了注浆量,解决了工作面随时出现的冒顶片帮问题,又避免了后期处理所带来的安全风险,为矿井安全生产提供可靠保障。

In view of the geological conditions of fully mechanized mining face in Majialiang Mine,grouting reinforcement is carried out in advance for the fracture zone along the working face along the channel,a reasonable grouting scheme is adopted and the effect of the grouting is monitored and analyzed,which not only reduces the quantity of grouting,but also reduces the amount of grouting.It solves the problem of roof fall in working face at any time,and avoids the safety risk brought by post-treatment,and provides reliable guarantee for mine safety production.
