Loess coverage area coal mining ecological restoration method
The invention provides a loess coverage area coal mining ecological restoration method, and relates to the technical field of mine geological environment and mining engineering. The method comprises the following steps that 1 ) a surface slope is determined before coal mining, 2) loess is subjected to mechanical parameter testing before coal mining, 3) surface loess slope stability is determined before coal mining, 4) loess of stable and non-stable regions in a coal mining process are reinforced by using different methods, and 5) a post-coal-mining stabilization stage is subjected to secondaryreinforcement, and settlement of a coal mining subsidence region is observed, after newly-added subsidence greater than 0.05m is monitored, secondary filling is carried out on cracks of the stable and the non-stable regions, a filling material is consistent with a filling material and method in the coal mining process until crack secondary development space is filled, 6) after repair, the coal mining subsidence region is covered with green vegetation, green mining of coal resources is completed, and ecology of the coal mining subsidence region has no significant degradation. The method is simple and easy to implement, water and soil loss is reduced, the vegetation survival rate is high, the repairing effect is good, no precious material is needed, and the method is economical and reasonable.
本发明提供一种黄土覆盖区煤炭开采生态修复方法，涉及矿井地质环境与采矿工程技术领域，包括以下步骤：1)煤炭开采前测定地表坡度，2)煤炭开采前对黄土测试力学参数，3)煤炭开采前判定地表黄土斜坡稳定性，4)采煤过程中对稳定区和非稳定区黄土分别使用不同方法加固，5)采煤后稳定阶段二次加固，采煤塌陷区沉降进行观测，当监测到大于0.05m新增沉陷时，对稳定区和非稳定区裂隙进行二次充填，充填材料与采煤过程中充填材料和方法一致，直至充填满裂隙二次发育的空间，6)修复后采煤塌陷区植被覆绿，完成煤炭资源绿色开采，采煤塌陷区生态无显著退化。该方法简单易实施，水土流失减少，植被生存率高，修复效果好，无贵重材料，经济合理。
