复杂地质条件下的突水疏放试验及水文地质意义

Draining test of mine water inrush under complex geological conditions and its hydrogeological significance

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 avoid lacking of awareness and usage of the process of water inrush, drainage test of mining water inrush on site were studied under complex geological condition on the base of a comprehensive analysis of the background field near the water inrush point and risk assessments. Results show that the process of mine inrush water under certain conditions can be successfully used as drainage test, and some following roles can be gained such as determining the water source, revealing hydrodynamic process, calculating hydrogeological parameters, and revealing the Karst medium conditions and reasons for water inrush, and so on. The new method has been carried out to get access to hydrogeological information which was difficult to get using routine methods, providing important scientific data for analyzing water inrush reasons, and dealing with efficiently water inrush disaster.
