摘要
本文通过乳山金矿改扩建工程的设计实践详细的介绍了在急倾斜薄矿脉中设计采用的新工艺方法.其中中深孔方案在厚度小于3m,尤其是在1～2m 的矿脉开采中推广意义较大.文中也对将要深入进行的采矿方法试验研究所面临的问题做了基本分析,并探讨了相应的对策.
Based on the designing practice of the extension and reconstruction of Rushan Gold Mine,this paper has introduced the design work of using a new technology for the mining of steep narrow veins.The alternative of medium-range hole is of greater significance of popularization to the mining of steep narrow veins under the conditions of less than 3 meters especially 1-2 meters in width of the vein.In addition, a basic analysis has been made on the problems produced in the testing and researches of the new mining method, and the counter-measures are also discussed in this paper.
