自然崩落法首次在武钢金山店铁矿试验成功,标志着我国地下采矿方法的研究有了新的突破,其经济价值是巨大的,在该矿的两个矿区推广应用,每年可节省705万元,在整个服务年限内可节省2.115亿元。本文对试验工作进行了总的回顾,对于采用RQD法以及其他工程地质方法评价矿石可崩性,对采用的对角线连续后退分次爆破拉底、放矿控制、支护形式以及采场的地压控制等工艺和技术均作了简要的叙述。 The first successful trial of the natural caving method at the Wushan Jinshandi Iron Mine marks a new breakthrough in the research on underground mining methods in China. Its economic value is huge. It is estimated that the project will promote the application of the two mining areas in the mine, saving a total of 7.05 million yuan , Saving 211.5 million yuan over the entire service life. In this paper, a general review of the experimental work is carried out. For evaluating the disintegrability of ores using the RQD method and other engineering geologic methods, the diagonal continuous retreating sub-type demolition pull-out, ore draining control, supporting form and stope Ground pressure control technology and technology are made a brief description.
