Ground surface crack treatment method for subsidence area
The invention provides a subsidence area ground surface crack treatment method, and relates to the technical field of ecological environment construction engineering. The method comprises the following steps: dividing a space above a first depth of a ground fracture as a catchment area; the space below the first depth of the ground fracture is sequentially filled with impervious layer filler, water-holding layer filler and surface soil cover layer soil from bottom to top in the vertical direction; wherein the component of the impervious layer filler mainly comprises coal-based solid waste-fly ash; the water holding layer filler mainly comprises coal-based solid waste-gasified fine slag, straw powder and organic fertilizer; the surface soil of the subsidence area is adopted as surface soil of the surface soil cover layer. Water and soil loss caused by ground fissures in the subsidence area can be effectively reduced, and threats of surface water to arid and semi-arid surface ecological safety and underground operation production safety of coal mines and the like are reduced.
本发明提供一种沉陷区地表裂缝治理方法,涉及生态环境建设工程技术领域;该方法包括以下步骤:划分地裂缝的第一深度以上空间作为汇水区;在地裂缝的第一深度以下空间,垂向由下至上依次填充不透水层填料、持水层填料和表土盖层土壤;其中:不透水层填料的成分主要包括煤基固废‑粉煤灰;持水层填料的成分主要包括煤基固废‑气化细渣、秸秆粉末和有机肥料;表土盖层土壤采用沉陷区的地表土壤。本发明可有效减少沉陷区地裂缝造成的水土流失,降低地表水对干旱半干旱的地表生态安全以及煤矿等地下作业生产安全造成的威胁。
