采煤地裂缝对水土资源的影响研究

通过对采煤地裂缝深度和覆岩导水裂隙带高度计算,两裂缝没有贯通。但不同类型的地下水在地表均有露头,地裂缝、裂隙成为良好通道,煤矸石淋滤液污染物通过河水、地表水污染了地下水,地裂缝影响了土壤水的运移,造成植被破坏、水土流失。文章主要研究了采煤裂缝影响下土壤含水量的变化对农作物的影响,为矿区水土资源保护、土地复垦提供了一定的依据。

Influential Research of Mining Ground Fissures on Water and Soil Resources

By the calculation of the depth of ground fissure and the height of water flowing fractured zone,we find that the two fractures have not joined up,but different types of ground water appear on the surface,so the ground fissure and fracture become good pathways.However,coal gangue leachate pollutes the groundwater through river and surface water;the fractures influence the transport of soil water and causes vegetation destruction and soil erosion.The paper studies the influence of soil moisture content on cr...
