陕西省汉江钢铁厂在选矿场储存尾矿碴,为了不使细粒矿碴流失,避免对下游河道水源污染,在略阳县硖口驿乡米箭沟沟口,用定向爆破方法修建了一座尾矿坝,采用土工织物作坝面反滤;土工织物涂刷石棉乳化沥青作坝前防渗,取得较好的效果。1987年6月陕西省冶金厅对该工程的设计和初步运用情况进行了审查,认为工程运用正常,效果良好。(一)工程概况尾矿坝初期设计坝顶高程730米,坝高36米,最终尾矿堆积高程816米。米箭沟沟
Han River Iron and Steel Plant in Shaanxi Province in the dressing site to store tailings ballast, in order not to make the loss of fine particles of ballast, to avoid water pollution in the lower reaches of the river, Lanyou Yi Township Miguansigou Mizoguchi Mizoguchi, using directional blasting method to build a Tailings dam, the use of geotextiles for dam surface filtration; geotextile asbestos-coated asphalt emulsion seepage control, and achieved good results. In June 1987, the Metallurgical Office of Shaanxi Province reviewed the design and preliminary application of the project and concluded that the project was operating normally with good results.
