庆阳南部地区煤矿地质环境预测评估

Predictive Assessment of Coalmine Geological Environment in Southern Qingyang Area

庆阳南部地区为鄂尔多斯盆地(甘肃)划定的煤炭重点开采区,内含矿区1个,在建和规划的矿井有6对。在研究区内矿区地质环境背景的基础上,结合矿山建设和开发中存在的地质环境背景、矿山开发规模、资源损毁、次生地质灾害及环境污染等主要环境地质问题,运用建立的灰色综合评估模型分析了矿山地质环境发展趋势。结果表明:除子午岭生态保护区及外围,研究区其他地区地质环境影响程度都为较严重-严重。通过对上述矿山地质环境趋势的分析,提出未来环境监测的重点应放在次生地质灾害、水环境和固体废物污染、土地资源损毁等方面。

The southern Qingyang area is a demarcated coal exploitation area in Gansu part of the Ordos Basin with one mining area and 6 constructing and planned coalmines. Based on study area mine geological environment background, combined with main environ?mental geology issues of mine construction and exploitation geological environment background, mine exploitation extent, resources de?struction, secondary geological hazards and pollution of environment etc., using gray comprehensive assessment model analyzed coalmine geological environment development trend. The result has shown that besides the Ziwuling ecological reserve and periphery, geological environment impacts are all rather serious to serious on other parts of the study area. Through above analysis, deemed that the future environmental monitoring should be focused on secondary geological hazards, water environment, solid waste pollution and land resources destruction etc.
