新桥硫铁矿帐幕注浆可行性的研究

A STUDY ON CURTAIN GROUT FEASIBILITY IN XINQIAO PYRITE MINE

新桥硫铁矿矿区水文地质条件复杂,地下水水量大且具有突发性,为此对东翼决定采用帷幕注浆治理。为研究其可行性,通过试验工程取得了大量的数据和经验,主要取得如下资料:(1)补充水文地质条件资料;(2)注浆参数确定;(3)注浆材料选取;(4)注浆工艺。试验结果表明在帷幕的主径流通道上,岩溶比原地质报告资料更为发育,但经过注浆试验仍达到了预期的目的。因此证明帷幕注浆是可行的。

The hydro-geology in the Xinqiao pyrite mine field is complicated, and ground water flow is big and of burst nature. For this reason it was decided that in the east flank of the deposit curtain grout will be conducted for ground water control. For feasibility study, extensive experiments have been performed and a lot of data and experiences have been obtained, including: 1. supplementary data on hydro-geological condition; 2. curtain grout parameters; 3. selection of grout materials and, 4. grout technology. Its results shown that on the main run-off passage of curtain grout the karst was more developed than is shown by the original geological report. The experiments achieved what was expected, leading to the ooncluson that curtain grout was feasibile for groundwater control in this mine.
