摘要
针对安阳煤矿深部5号煤层开采可能受到的水害威胁,利用"三图-双预测"评价体系和"突水系数"评价方法,分析首采面5号煤开采所面临的主要水害问题,并有针对性地提出超前综合物探探查、钻探验证,顶板水疏放,底板注浆加固及排水系统建设等综合防治水技术与对策,以确保矿井的安全生产。
No.5 coal seam mining in Anyang Mine could be threatened by water hazards.With the evaluation system,three-graph-double-prediction,and the evaluation method on water burst coefficient,major water hazards faced by the initial mining face were studied.A comprehensive water control technology was proposed,including in-advance geophysical detection,drilling verification,roof water draining,floor grouting reinforcement,and water drainage system construction,to guarantee the safe production in the mine.
