摘要
推土机——铲运机开采露天砂金矿床在我国尚属一项新工艺。本文介绍了该工艺在黑龙江省呼玛金矿局5号矿体上的开采工艺过程及试验结果。并对该工艺的特点、适用性等作了论述。试生产证明此种工艺特别适用永久冻土发育的矿体与不适合采金船开采的小而富的矿体。该工艺的开采效率接近150升采金船,成本较采金船略高。
The bulldozer-scraper mining nethod has begun to apply in China's gold placer mines.To mine the No.5 deposit in Huma county,Heilong jiang province,this method was adopted.Here, the mining procedure and the results of the application in Huma as well as the features and the adaptability analysis of this method are described. The application shows that the bulldozer-scraper mining method is very suitable to the placer deposits that loaded in permafrost area, also it is adaptable to apply this method in rich but small gold deposits that are not available in dredging mining. The mining efficiency of this method has been proved to be nearly as high as that of the dredging method,but it's production cost is slight higher.
