影响矿井安全的多含水层矿井涌水构成分析

Analysis of Composition of Mine Inflow from Complicated Multi-Aquifer Affecting Safety Production in Coal Mines

为了判断影响矿井安全的多含水层矿井涌水的构成,结合模糊聚类法、piper三线图法对矿区主要充水含水层的水化学成分进行了分析,在确定各充水含水层离子成分特征值的基础上,首次采用水化学离子成分守恒分析方法对矿井涌水的构成进行了定量分析.结果表明矿井日常涌水量中来自寒武系灰岩含水层的占25.22%,约为202.03 m^3/h,与实际观测的200 m^3/h较接近.该方法评价结果可靠,且简单易行,能准确、便捷地对矿井涌水的构成及未知突水水样的水源进行判别,最终为煤矿采取有效的矿井防治水手段和实现安全生产提供决策依据.

In order to identify the composition of mine inflow from complicated multi-aquifer, the water eigenvalue is determined by analyzing water chemical characteristics in major aquifers by fuzzy clustering and piper diagram. On the basis of this, the composition of mine inflow is quantitatively studied with the method of ions conservation of hydrochemistry for the first time. The result shows that the daily mine inflow coming form Cambrian limestone aquifer accounts for 25.22% of the total, approximately 202.03 m^3/h, which is very similar to the real 200 m^3/h. This method can efficiently and accurately distinguish the source of water inrush and the composition of mine inflow. Further more, it is helpful for the decision-making to adopt effective method for the prevention of water inrush and the safety production of coal mine.
