摘要
在露天煤矿开采过程中,原有的土地结构和植被会遭到破坏,进而导致土壤侵蚀等环境污染问题。为此,提出露天煤矿减损开采及生态环境修复治理技术。依据煤层倾角计算煤矿开采深度,借助遗传算法求取露天煤矿减损开采错距,结合约束方程建立煤矿动态减损开采序列,从而确定L型煤矿减损开采方案,减少了因开采活动造成的土地破坏和生态环境污染问题。同时,通过一系列具体措施促进矿区生态环境的快速恢复,提高矿区的可持续发展能力。结果表明,所研究的技术在露天煤矿减损开采过程中,能够有效缩小土地占用范围,具有更好的减损开采效果。
During the open-pit coal mining process,the original land structure and vegetation will be damaged,leading to environmental pollution problems such as soil erosion.Therefore,technologies for reducing mining losses and ecological environment restoration in open-pit coal mines are proposed.Based on the dip angle of the coal seam,the mining depth of the coal mine is calculated,and the offset distance of the open-pit coal mine is obtained by using genetic algorithm.Combined with the constraint equation,a dynamic reduction mining sequence of the coal mine is established to determine the L-shaped coal mine reduction mining plan,which reduces the land damage and ecological environment pollution caused by mining activities.At the same time,a series of specific measures will be taken to promote the rapid restoration of the ecological environment in the mining area and improve its sustainable development capacity.The results indicate that the studied technology can effectively reduce the land occupation range and have better reduction and mining effects in the process of open-pit coal mine reduction and mining.
