近矿体帷幕注浆技术在太平矿区的应用

Application of Curtain grouting technology in Taiping Mine underground

结合太平矿区水文地质条件,采用近矿体帷幕注浆技术治理水害,通过布置穿脉探水钻孔注浆工程和加密注浆工程,揭露查清矿井水文地质特征,并进行纵横交错的钻孔注浆,最终在矿床顶板围岩形成一定厚度的注浆盖层,切断了含水层与矿井间的水力联系,既保证了矿井安全开采,又保护了地下水资源。

Combined with the hydrogeological conditions of Taiping Mine, Using near orebody curtain grouting technology to control water disasters, By arranging the grouting project with water exploration drilling in crossing veins way and the cryptographic grouting project, Exposing and finding out the hydrogeological characteristics of Mine, and implementing crisscross drilling grouting, finally forming a Grouting cap with a certain thickness in roof surrounding rock, Cutting off the hydraulic connection between the aquifer and mine, not only guaranteing the safety of mines exploitation but also protecting the groundwater resources.
