大采深矿井开采底板突水防治对策探讨

Discussion on the prevention and control of water inrush from floor in the mining of large mining depth

针对X矿开采深部4#煤层底板突水问题,分析了该矿地质、水文地质条件,分别对工作面掘进和回采进行了危险性评价,并提出了利用奥灰局部疏水降压、增强煤层底板隔水层阻水能力、降低煤层底板破坏深度、构建开采期间底板突水预警系统来降低煤层底板突水风险的综合措施。

Aiming at the deep 4# coal seam floor inrush water x mine, analyzes the mine geological, hydrological and geological conditions, respectively the risk of working face and beading were evaluation, and proposes the use of local drainage and depressurization, enhancing the floor vibration aquifer water resisting ability, reducing the coal seam floor failure depth, constructing the floor water inrush early-warning system during the mining to reduce the comprehensive measures of coal seam floor water inrush risk.
