摘要 土壤入渗特征是评价地表保水性的主要指标值,是衡量地表生态系统的稳定性的主要参数。开采导致土壤入渗特征发生改变,为得到开采对土壤入渗特征的影响,在乌兰木伦矿选取实验工作面,采用现场实测的方法测定了随工作面推进过程的土壤稳定渗流速率,得到了采动作用下土壤渗流速率的变化规律,研究结果表明,土壤可进行自修复,自修复周期约为从塌陷 3 个月开始,至塌陷 5 个月基本恢复到原始状态。 The characteristics of soil infiltration are the main index values for evaluating surface water retention, and are the main parameters to measure the stability of surface ecosystem.Mining caused soil infiltration characteristics change, for mining influence on soil infiltration characteristics, Aaron ore selecting experiment working face were ulam in wood, adopt the method of in-situ test to determine the stability of soil seepage rate along with the working face advancing process, obtained the mining action with the change rule of soil seepage rate, the results show that the soil can be self-healing, since the repair cycle is about from the beginning of the collapse in 3 months, five months to collapse back to the original state.
