Surface water damage prevention and control method and system for steeply inclined coal seam mining
The invention discloses a surface water damage prevention and control method and system for steeply inclined coal seam mining, and relates to the technical field of geological engineering and mining engineering.The method comprises the steps that the mining thickness and position of a steeply inclined coal seam are obtained; the setting position of a water retaining dam is determined according to the water catchment amount constraint condition, the mining thickness and position of the steeply inclined coal seam and the water flow direction of the surface water, and the water retaining dam is arranged at the setting position; and when the steeply inclined coal seam is mined, if no rainfall exists, filling the generated ground surface crack, arranging a ground surface drainage pipe for drainage based on the water retaining dam, if rainfall exists, filling the generated ground surface crack, arranging a ground surface drainage pipe based on the water retaining dam, and implementing water resource transfer drilling for cooperative drainage. According to the method, the complexity of surface water damage prevention and control is reduced, the method is more environment-friendly, and the safety of steeply inclined coal seam mining is improved.
本发明公开一种针对急倾斜煤层开采时的地表水害防治方法及系统，涉及地质工程与采矿工程技术领域，所述方法包括：获取急倾斜煤层的开采厚度和位置；根据汇水量约束条件、急倾斜煤层的开采厚度和位置以及地表水的水流方向确定拦水大坝的设置位置，并在设置位置处设置拦水大坝；当进行急倾斜煤层开采时，若无降雨，则对产生的地表裂缝进行充填，并基于拦水大坝设置地表排水管进行排水，若有降雨，则对产生的地表裂缝进行充填，并基于拦水大坝设置地表排水管并实施水资源转移钻孔协同排水。本发明降低了地表水害防治的复杂度，更加环保，提高了急倾斜煤层开采的安全性。
