摘　　要：为了准确评估煤矿开采对生态环境的影响并提出应对措施,以黄河流域露天煤矿为例,结合实地调查研究,评估开采活动对资源环境承载力的影响。结果表明:整体上,矿区综合承载力处于低风险状态,但采掘场和外排场存在水、土壤环境超标问题;地下水环境良好,但需关注地表水硫化物及锰(Mn)超标问题;土壤环境需关注外排场pH值及铵态氮超标问题;矿区植被恢复良好,植被覆盖度高,整体属于低风险。To accurately assess the impact of mining on the ecological environment and propose countermeasures,we evaluated the impact of mining activities on the carrying capacity of resources and the environment by taking the open-pit coal mines in the Yellow River basin as an example with field investigation.The results showed that overall,the comprehensive carrying capacity of the mining area is in a low-risk state,but the water and soil environment exceed the standard in the mining site and discharge site.The groundwater environment is good,but attention should be paid to sulfides and manganese(Mn)exceeding the standard in surface water.The soil environment needs to pay attention to the pH and ammonium nitrogen exceeding the standard in the discharge site.The vegetation in the mining area is well restored,with high vegetation coverage and overall low risk.
