德兴铜矿是采用机械化开采的大型露天矿。据初步设计,最大露天边坡固定帮高差达700～800米,并且矿山服务年限长,对边坡固定帮的稳定性要求较高,以保证在矿山服务年限内不发生大的滑坡。 1981年以前,我们曾采用大爆破的方式扩帮再请民工修整边坡(即普通法),但工效低,成本高,施工期长;而且边坡受大爆破的冲击破坏,稳定性、完整性差,不平整度高达1.0～2.0米,边坡质量远达不到要求。
Dexing Copper Mine is the use of mechanized mining large opencast mine. According to the preliminary design, the maximum height of the open slope is 700-800 meters, and the service life of the mine is long, which requires high stability of the slope fixed gang, so as to ensure that no major landslide occurs during the service life of the mine. Before 1981, we used the method of large-scale blasting to expand and help re-engineer the slope (common law), but with low work efficiency, high cost and long construction period. Moreover, the slope was damaged by the impact of the large-scale blasting and its stability and integrity Poor sex, unevenness of up to 1.0 to 2.0 meters, the quality of the slope far failed to meet the requirements.
