Method for treating surface collapse crack caused by mining of shallow-buried thick coal seam based on check dam group
The invention discloses a method for treating a surface collapse crack caused by mining of a shallow-buried thick coal seam based on a check dam group. The method is characterized by comprising the following steps of calculating crack area treatment parameters based on an intra-section earth excavation and filling balance principle; arranging the check dam group in the crack area, and determiningthe type and structure of check dams; designing the spacing of the check dams; preliminarily selecting the positions of the check dams and optimizing the positions of the check dams; and then performing building of the check dams, constructing of the check dams, crack treatment, side slope renovation and vegetation recovery design. In the case of the method, according to the development characteristics of wide and large cracks, an artificial channel is formed by performing local terrain transformation on the crack area, then water and soil loss control is performed through the check dam grouptechnology for soil storage and water retention, and biological measures are used in combination for ecological restoration; and the achievement is helpful for promoting ecological restoration and ecological civilization construction of western mining areas.
本发明公开了基于谷坊群的浅埋厚煤层开采地表塌陷裂缝治理方法,其特征是基于断面内土方挖填平衡原则计算裂缝区治理参数；在裂缝区布设谷坊群，确定谷坊类型及结构；对谷坊间距进行设计；初步选定谷坊位置并进行优化；然后进行谷坊修建、谷坊施工、裂缝治理边坡整治及植被恢复设计。本发明根据宽大裂缝的发育特点，通过对裂缝区进行局部地形改造，形成人工沟道，然后利用谷坊群技术进行水土流失控制，蓄土保水，结合生物措施，进行生态修复。该成果有助于促进西部矿区生态恢复及生态文明建设。
