| 摘 要： | 针对演马矿煤矸石矿井填充可能造成的环境影响,在实验室环境中制定了两种动态淋溶控制实验,来模拟煤矸石矿井回填后的控制效果。其一是将煤矸石与粘土均匀混合填充;其二是将煤矸石与粘土分层填充。通过这两种控制实验的比较分析可知,粘土层的吸附、转化作用,对控制煤矸石中有害元素的溶出有一定的效果。考虑分层样对F-有良好的控制效果,建议选择分层方法进行煤矸石矿井填充。

| Abstract: | Aiming at the possible environmental impacts during mine-fill with the coal gangues from Yanma mine,two dynamic leach experiments were designed under simulation conditions in laboratory for analyzing the control effects: one is to mix coal gangues with clay uniformly,another is to fill the coal gangues and clay into layers seperately.It can be seen from the experimental analysis that in two controlled experiments,the absorption and transformation functions of clay layer have a certain effect on the control of stripping of harmful elements.Considering the layering treatment have better effect on the control of stripping of F~-,it is suggested that the layered treatment should be chosen during mine-fill with coal gangues. |
