应用下向分层进路回采胶结充填采矿方法开采大水清金矿蚀变岩型矿床是一种行之有效的采矿方法。二年多的生产实践表明,用这种方法开采该矿Ⅰ—2号极碎矿体,不仅技术上可行,生产稳定、作业面安全可靠,而且企业的经济效益显著,能充分的回收黄金资源,利国利民。在改进充填工艺和提高采场生产能力、降低充填成本的基础上,用下向胶结充填采矿法开采破碎不稳固的难采矿床是有广阔前景的采矿方法,具有使用和推广价值。 使用钢筋混凝土盖板法成功的解决了露天转地下开采,这是投资少、见效快、施工简便、没有井下工程和不积压矿量的一种有效方法。对有类似条件的矿山可参考和借鉴。
The application of stratified entry mining to cementing and filling mining method to mine Dashuiqing gold alteration rock type deposit is an effective mining method. More than two years of production practice show that using this method to mine the very fine ore body Ⅰ -2, not only technically feasible, stable production, safe and reliable operation, and the significant economic benefits of enterprises, can fully recover the gold resources , Li Guo Limin. On the basis of improving the filling technology and raising the production capacity of stope, and reducing the filling cost, it is a promising mining method to exploit the cemented and reclaimed mining method under the direction of cementation and filling, which has the potential to be used and popularized. The use of reinforced concrete cover the successful solution to the open pit to underground mining, which is less investment, quick, easy construction, there is no underground engineering and non-backlog of an effective measure. For similar mines can refer to and learn from.
