东河湾铁矿井下涌水治理研究

Study on the Control of Underground Water Inrush at Donghewan Iron Mine

武安东河湾铁矿 3Fe2 矿体 ,井下涌水量 15 0 0m3/h ,在疏干排水影响相邻单位用水的情况下 ,采用井下帷幕注浆堵水方案 ,使井下涌水量降至 40 0m3/h。很好地解决了井下排水地面闹水荒的矛盾 ,并为本矿采矿生产创造了良好的条件 ,投产

In 3Fe 2 orebody of Wuan Donghewan Iron Mine, there was water inrush of 1500 m 3/h. As its drainage could affect the water supply of neighbouring units, the method of underground curtain grouting for water blocking was used to reduce the water inrush to 400m 3/h. As a result, the contradiction between underground drainage and surface water shortage was well solved and good conditions were created for the mining, with the production doubled in the two years since the mine commissioning.
