摘要
为进一步实现对露天煤矿矿山地质环境的综合评价,以彬长露天煤矿当前频发的矿山地质环境问题现状为基础,基于最优组合赋权理论的可拓学评价方法,得到研究区域生态弹性力、资源环境承载力以及开采压力评价结果。结果显示,高稳定性地质单元占研究区总面积的41.10%,中等稳定性地质单元占24.69%,低稳定性地质单元占7.67%;高承载力地质单元占研究区总面积的55.94%,中等承载力地质单元占6.58%,低承载力地质单元占29.85%,承载力弱的地质单元占7.64%;开采压力弱的地质单元占研究区总面积的73.74%,开采压力低的占0,开采压力中等的占1.64%,开采压力高的地质单元占24.62%。评价结果揭示了该地区环境承载力的现状和分布特点,为该地区的可持续发展提供了重要参考。在未来的规划和管理中,应重点关注低稳定性和低承载力的区域,采取有效措施改善其环境条件。同时,应加强对高开采压力区域的监控和管理,以确保矿区的长期稳定和可持续发展。
In order to further realize the comprehensive evaluation of the geological environment of the open-pit coal mine,based on the current frequent geological and environmental problems in the Binchang open-pit coal mine,the evaluation results of the ecological elasticity,resource and environment bearing capacity and mining pressure of the research area were obtained based on the extension evaluation method of the optimal combination empowerment theory.The results showed that high stability geological units accounted for 41.10%of the total area of the research area,medium stability geological united for 24.69%,and low stability geological united for 7.67%.High bearing capacity geological units accounted for 55.94%of the total area of the research area,medium bearing capacity geological units accounted for 6.58%,geological units with low bearing capacity accounted for 29.85%,and geological units with weak bearing capacity accounted for 7.64%.The geological units with weak mining pressure accounted for 73.74%of the total area of the research area,low mining pressure for 0,medium mining pressure for 1.64%,and geological units with high mining pressure for 24.62%.The evaluation results reveal the status and distribution characteristics of environmental bearing capacity in this region,and provide an important reference for the sustainable development of this region.In future planning and management,emphasis should be placed on areas with low stability and low bearing capacity,and effective measures should be taken to improve their environmental conditions.At the same time,the supervision of high mining pressure areas should be strengthened control and management,to ensure the long-term stability and sustainable development of the mining area.
