半封闭式帷幕注浆堵水技术在铜山铜铁矿的应用

Application of Semi-enclosed Curtain Grouting for Water Plugging in Tongshan Copper & Iron Mine

根据铜山铜铁矿水文地质条件,从治理的必要性、方案的可行性、经济的合理性等方面出发,在充分考虑施工过程中可能出现的问题及相应预防处理措施的情况下,选用半封闭式帷幕堵水方案,确定了帷幕注浆的参数值。该方案不仅具有安全效益和经济效益,同时具有保护地下水资料的社会效益。该项技术适用范围广,工艺成熟,易于实施,可作为深井大水矿山地下水治理的主要技术方法予以推广。

According to the hydrogeological conditions of Tongshan CopperIron Mine,the necessity of treatment,the feasibility of the program and the economic rationality,a semi-enclosed curtain water plugging scheme has been chosen to determine the parameters of curtain grouting by fully taking all the problems occurring in the construction process and the corresponding preventive measures into consideration. This scheme not only has highly safety benefits and economic efficiency,but also has social benefits of protecting underground water resource. This technology has such advantages as wide application scope and mature technology,which can be applied widely as a major technology of treating underground water in deep-wells mines.
