摘　　要：地表资源日渐枯竭,大多数露天矿正处于闭坑或转地下状态,有效治理和利用废弃露天坑成为生态修复的主要问题。结合某矿山废弃露天坑自然条件及太阳能发电优势,构建废弃露天坑光伏发电物理模型,并以全天光照情况为基础,确定了太阳能电池板的摆放方案。研究结果表明:太阳能电池板安装位置和摆放角度对其产电效率起到决定性作用;在废弃露天坑的中上层台阶倾斜摆放太阳能电池板产电效率最高,高于水平摆放太阳能电板产电效率的40%左右,集中产电时间为中午时段。研究结果为废弃露天坑的高效利用提供了新的思路。With the depletion of surface resources,most open-pit mines are in the state of pit closure or underground conversion.Effective treatment and utilization of abandoned open-pits has become the main problem of ecological restoration.Combined with the natural conditions of an abandoned open pit in a mine and the advantages of solar power generation,a physical model of photovoltaic power generation in an abandoned open pit was constructed.Based on the all-day illumination,the placement scheme of solar panels was determined.The research results show that the installation and placement position and placement angle of solar panels play a decisive role in their power generation efficiency.In the middle and upper steps of the abandoned open pit,the power generation efficiency of inclined solar panels is the highest,which is higher than about 40%of the power generation efficiency of horizontal solar panels,and the centralized power generation time is noon.The research results provide a new idea for the efficient utilization of abandoned open-pit.
