中文摘要:
      胶东地区金矿开采历史悠久,20世纪70—90年代产生了大量稳定性差的采空区。在采空区治理过程中,一般采取注浆法进行充填,以消除地面塌陷隐患。该文以文登市大时家废弃银金矿历史遗留采空区治理项目为例,针对治理区地下水资源贫乏的现状,首次选用中粗砂方案,采取干注法和水注法相结合的注砂方法进行充填,从而达到既消除采空塌陷地质灾害隐患,又形成新的蓄水空间的目的。
英文摘要:
      The gold mining in Jiaodong area has a long history. In the 1970s and 1990s, a large number of goafs with poor stability have been formed. In the process of the goaf treatment, the grouting method is generally used for the top filling to eliminate the hidden danger of the ground collapse. In this paper, setting the historical and abandoned goaf treatment project of the abandoned silver and gold mine in Wendeng city as an example, pointing to present condition of poor groundwater resources in the treatment area, the medium coarse sand scheme is selected for the first time, and the sand injection is carried out by using the combination of dry injection method and the water injection method. Thus, the purpose has been gained for eliminating the hidden dangers of geological disasters caused by goaf collapse and forming a new water storage space.
