Impact on ground-water qualities during mine-filling with coal gangues from Yanma coal company;
演马矿煤矸石矿井填充对地下水环境的影响
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.
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。
