Water storage method for windy beach mining area
The invention belongs to the technical field of coal mining, and particularly relates to a wind sand beach mining area water storage method which innovatively utilizes directional drilling to enable a wind sand beach aquifer in a skylight area to be communicated with a wind sand beach aquifer in a non-skylight area, rapid cross-regional supply of water resources is improved, and after the supply degree is increased, the water storage amount of the whole mining area is greatly increased; in order to prevent a large amount of water resources from being drained through earth surface spring water, the seepage path of an original wind sand beach aquifer is changed through arrangement of the coal pillars, compared with a mining area, the settlement amount of a coal pillar arrangement area is small, drainage of spring water is blocked or reduced, the migration path of underground water is increased, and therefore the infiltration amount is increased; according to the method, the amount of water resources converted from wind sand beach infiltration to other aquifers is increased, and the problem of water shortage is effectively relieved through storage of water resources; lots of water resources are prevented from entering the goaf, and the water quality is improved; meanwhile, the problem of excessive water accumulation in the wind-blown sand beach area is effectively controlled, and the safety risk of coal mining is reduced.
本发明属于煤矿开采技术领域，具体涉及一种风沙滩矿区储水方法，本发明创新利用定向钻使得天窗区风沙滩含水层与非天窗区风沙滩含水层连通，提升了水资源快速跨区域补给，加大补给程度后使得整个矿区含储的水量大幅度增加；为防止大量的水资源通过地表泉水排泄，因此通过煤柱的留设，改变了原有的风沙滩含水层渗流路径，留设煤柱区相对于开采区沉降量小，阻断或减少泉水的排泄，增加地下水的运移路径，从而增加了下渗量；本发明提升了由风沙滩入渗转化为其他含水层的水资源量，水资源的存储有效缓解了缺水的问题；避免了大量水资源进入采空区，水质有所提升；同时有效控制了风沙滩区积水过量的问题，减少了煤炭开采安全风险。
