矿山开采区地下水基础环境状况调查评估研究
|
摘要
在收集评估区域范围内污染源荷载、水文地质参数和地下水功能价值等资料的基础上,对黑龙江省某矿山开采区开展了地下水基础环境状况调查评价。综合评价结果表明6个点位水质均为较差,主要是因为总溶解性固体和总α放射性指标较高。污染因子评价结果表明了矿区周边地下水大部分指标未受到污染,仅总硬度和高锰酸碱盐受到较轻污染。结果得出,调查区地下水中溶解性总固体和总α放射性较高,超标原因是矿山部分岩石中含有较高的放射性物质导致的地下水中总α放射性较高,其余指标均在III类水质范围内。
Based on the collection and assessment pollution load, hydrogeological parameters and groundwater function value data, evaluation of groundwater basic environmental condition was carried out in Heilongjiang province for mining area. The comprehensive evaluation results show that the water quality of the six sites is poor. The evaluation results of pollution factors show that most indexes of groundwater around the mining area are not polluted, only the total hardness and permanganate alkali salts are lightly polluted. The results shows that the total soluble solids and total alpha radioactivity in groundwater are higher in the investigation area, the reason is high total alpha radioactivity in groundwater caused by high radioactivity in some rocks of Mines, the other indicators are all within the range of three types of water quality.
