摘　　要：为解决矿井涌水量预计误差较大、矿山排水能力无法适应矿井突水的问题,以山东龙固矿井为对象,根据矿井涌水量多年动态变化规律分析影响矿井涌水量大小的主要因素,揭示采动过程中充水因素变化对涌水量大小的影响,并在此基础上,采用数值法实时预测采掘进程中矿井涌水量的动态变化。结果表明,与以往采区范围固定不变的模拟方法相比,考虑按工作面开采的时间先后顺序进行涌水量的预测,实时调整新采区内的虚拟开采井,此种预测方法使矿井涌水量预测结果更逼近真实,减小了计算误差。Aiming at the prediction error of mine water inrush and incapability of the mine drainage system, the major factors influencing mine water inrush amount were analyzed based on the law of dynamic variation in Longgu mine, the influence of water - filling factor variation on mine water inrush during mining was revealed, and on this basis, numerical method was used to predict the dynamic variation of mine water inrush during mining. The results show that, compared with previous simulation methods with mining area range fixed, the new prediction method is more accurate, which takes time sequence of working face mining into consideration, when predict the water inrush amount, realizing real - time adiust of the virtual production shafts of new mining area.
