为了克服以往对突水过程认识和利用上的不足,通过综合分析突水点附近背景场及风险评估,利用山西某矿井巷道突水在复杂地质条件下的流场进行了疏放实验。结果显示,矿井突水在一定条件下可作为疏放试验来加以利用,可用来确定补给水源、记录突水量变化过程、获取含水层水文地质参数、揭示岩溶介质条件及突水原因等。该方法的实施,获取了常规方法难以获取的水文地质信息,为进一步分析突水原因、合理高效处置突水灾害提供了重要的科学数据。
In order to overcome the problems of understanding and using of water inrush process in the past, by comprehensively analyzing the background field and risk assessment near the water inrush point, the flow field of the water inrush of a mine shaft in Shanxi is analyzed in the complex geological conditions. The results show that the water inrush can be used as a drainage experiment under certain conditions. It can be used to determine the source of recharge water, record the process of water inrush, obtain the hydrogeological parameters of aquifer and reveal the reason of karst medium and the reason of water inrush. The implementation of this method has obtained the hydrogeological information which is difficult to obtain by the conventional methods and provides important scientific data for further analysis of the reason of water inrush and reasonable and efficient disposal of water inrush.
