1975年3月白银露天矿一采场东边坡1799运输公路路基发生滑坡。这段路基长270米,宽10米,高10～36米。为了尽快恢复正常生产,采取了扩宽路面、局部清坡和人工加固边坡的措施,例如用抗滑桩和混凝土挡墙稳定坡脚,用金属锚杆加固坡面,局部用混凝土护坡的综合治理等。工程用了两个月,施工用料见表1。随着采场的延深,滑面也延深到了下一台阶,使1775～1763平台产生错动,所以,于1976年又进行了第二次加固工程。在1763平台50米长的范围内打了27根抗滑桩,分两排梅花状排列(图1)。 In March 1975, a landslide occurred on the 1799 transport highway roadbed at the east side of the Baiyue Opencast Mine. This roadbed is 270 meters long, 10 meters wide and 10 to 36 meters high. In order to resume normal production as soon as possible, measures have been taken to widen the road surface, partially clear the slopes, and artificially reinforce the slopes, such as stabilizing the slope foot with anti-slide piles and concrete retaining walls, reinforcing the slopes with metal anchors, and integrating the local concrete slope protection. Governance and so on. The project was used for two months. The construction materials are shown in Table 1. With the deepening of the stope, the sliding surface has also been extended to the next level, resulting in a shift in the platform between 1775 and 1763. Therefore, a second reinforcement project was carried out in 1976. Twenty-seven anti-slide piles were drilled in a range of 50 meters long on the 1763 platform, arranged in two rows of plum blossoms (Figure 1).
