| 中文摘要:由于矿产资源及采石场存在的不规范开采，造成了山体裸露、植被破坏、水土流失、扬尘滚石，且存在着地质灾害等安全隐患。国家和各级地方政府都高度重视矿山的生态恢复，在矿山生态恢复治理中因开采形成的高陡边坡常见的传统治理方法主要为削坡，即由上而下阶梯式完成坡面的削整，再进行平台及坡面绿化，但该施工方法受矿山的不规范开采影响，存在着一定的施工难度，工程量较大，同时会进一步对生态环境造成破坏，且坡脚栽植绿化植物完全覆盖坡面时间较长。鉴于这些情况，创新试验了“一种矿山环境恢复治理的喷砼飘台结构”（简称“喷砼飘台”）新技术，通过现场的技术攻关试验，解决了矿山及采石场生态恢复治理中高陡峭边坡施工难的技术问题，减少了对生态环境的破坏。简易迅速的施工，见效快，同时对地质灾害隐患也进行了有效的治理。 |

| Abstract:There are some safety risks such as exposure of the mountain, vegetation damage, soil erosion, rolling dust, geological hazards due to the irregular exploitation of mineral resources and quarries. The state and local governments at all levels attach great importance to the ecological restoration for mines. In the ecological recovery and management for mines, traditional treatment for high and steep slopes from mining is mainly slope grading; that is, the slope is trimmed from the top to the bottom, and then the platform and the slope are greened. However, with this method, there is some construction difficulty, and a large amount of work due irregular mining operations; meanwhile, it will further damage the ecological environment, and it takes a longer time to cover the slope with green plants. In view of these circumstances, a new type of technology called “shotcrete floating platform for the restoration of the mining environment” (in short “shotcrete floating platform”) was innovatively developed. Field experiments demonstrated that it solved the technical difficulty in high steep slope treatment for ecological recovery at the mines and quarries, and reduced additional destruction of the ecological environment with simple and rapid construction, and quick effect; at the same time it provided effective control of geological hazards. |
