In order to study the effect of waste rock piling on water environment,the character of water quality change after the waste rock is dipped into water is analyzed by eluviation experiment.
为了研究废石堆砌对水环境的影响,通过对废石做淋溶实验,分析了出入水的水质变化规律,对废石衍生环境效应的过程、机制、影响因素方面进行讨论,揭示了人们容易忽视的酸性水中硫酸根、总硬度、微量金属离子的动力学变化机理,指出矿山废石对水环境的污染不至限于使水质酸化,硫酸根、总硬度也会大幅度提高,废石堆放应充分考虑当地的地理气候及水文条件,合理堆放,减少污染。
Because of the lack of filling materials, and to reduce the production cost, a waste rock filling system in the underground was constructed.
为了解决井下充填料不足 ,并降低生产成本 ,在井下建立了废石破碎充填系统。
Based on theoretical calculation and in-situ test results,distribution and emissions of radioactive nuclides of uranium tailings impoundment and waste rock pile sites are analyzed in this paper.
