摘　　要：工作面顶板突水和水资源短缺是我国山西地区矿区面临的两大难题,采用现场实测、相似模拟和理论分析相结合的方法,构建了试验矿井上行和下行开采的物理模型,分析了不同开采顺序下顶板突水的动态演化规律和突水机理。结果表明,晋华宫煤矿下向开采后,11号煤层导水裂隙最大发育高度为43.1 m,裂隙采动比为14.4。在采动裂隙与顶板含水层的连接处形成突水通道,煤层的安全开采受到采空区突水的威胁。因此,通过比值检验和“三带”判别方法确定了上行开采的可行性,并对比了上行开采和下倾开采时的突水通道演化,提出采用上行开采控制顶板突水,该研究为晋华宫煤矿顶板突水灾害的防治提供了依据。Working face roof water breakout and water shortage are two major problems faced by mines in Shanxi,China.Using a combination of on-site measurement,similar simulation and theoretical analysis,a physical model of upward and downward mining in the test mine was constructed,and the dynamic evolution law of roof water breakout and the mechanism of water breakout under different mining sequences were analyzed.The results show that,after downward mining in Jinhua Palace Mine,the maximum development height of water-conducting fissure in 11#coal seam is 43.1 m,and the ratio of fissure mining is 14.4.A water-surge channel is formed in the connection between the mining fissure and the roof water-bearing layer,and the safe mining of 11#coal seam is threatened by water-surge of the mining airspace.Therefore,the feasibility of upward mining was determined by ratio test and"three bands"discrimination method,and the evolution of water-surge channel was compared between upward mining and downward mining,and it was proposed to use upward mining to control the water-surge on the roof plate,which provides a basis for the prevention and control of the water-surge disaster on the roof plate of Jinhuagong Coal Mine.
