摘　　要：为查明杨柳矿小沈家断层对煤层开采的影响以及确定防水煤柱留设的合理宽度,以井田10412工作面为研究对象,采用数值模拟方法,对不同煤柱宽度条件下工作面回采过程中煤层顶、底板变形及应力分布进行了研究。结果表明:工作面推进距断层95m处,断层会直接导致顶板变形,并容易形成导水通道。因此,建议10412工作面小沈家断层防水煤柱留设宽度应不小于36.53m。该研究结果为煤矿安全生产及防、突水提供了参考依据。In order to find out the influence of Xiaoshenjia-fault(XSJF)in Yangliu mine on coal seam mining and determine the reasonable width between waterproof coal pillars,the deformation and stress distribution were studied of coal seam top and floor in the mining process of 10412 working face under the condition of different coal pillar width with the numerical simulation method.It was found that 95m away fromXSJF,the fault would directly lead to roof deformation and easy to form a water diversion channel.Therefore,it is suggested that the reserved width between waterproof coal pillars of XSJF in 10412 working face should not be less than 36.53m,which provides a reference for the safety production and water inrush prevention of Yangliu Coal-mine.
