皖北矿区主要突水水源水文地质特征研究

Study on hydrogeological feature of the main pouring water aquifers within the mining area in northern Anhui

在皖北矿区的临涣、海孜等矿对4个主要突水含水层采取了38个水样,做了放射性同位素氚含量分析,绘制了四含水、太灰水和奥灰水氚含量等值线图.四含水氚含量出现在任楼矿、海孜矿和临涣矿3个高值区,w(T)=10～14Tu;煤系水最大氚含量在任楼矿,为6Tu,其余测定均小于5Tu;太灰水最大氚含量出现在张庄和杨庄矿,以此为中心向四周逐渐减小;奥灰水在二电厂和物探队出现w(T)=16～20Tu的高值区.在此基础上,得出皖北矿区主要突水、含水层的循环特征及其相互间的水力联系.

Took 38 water samples from four of the main pouring water aquifers in the mining area in northern Anhui such as Linhuan Mine, Haizi Mine and so on, analyzed the content of the radioactive isotope tritium, and drew the content of tritium isoline figures about the fourth aquifer, the Taiyuan limestone aquifer and the Ordovician limestone aquifer. The w(T) in the fourth aquifer presented Renlou Mine, Haizi Mine and Linhuan Mine three high value districts, w(T)=10～14 Tu. The highest value of w(T) in the coal measures occurred in Renlou Mine, it was 6 Tu and others were all less than 5 Tu. The maximal w(T) of the water in Taiyuan limestone aquifer occurred in Zhangzhuang and Yangzhuang Mine, and took it as a center towards around reduced gradually. The water in Ordovician limestone aquifer appeared w(T)=16～20 Tu high district in the Second Electric Power Plant and the Geophysical Prospecting Team. The groundwater cycle features and their hydraulic connections of the main pouring water aquifers in the mining area in northern Anhui were concluded on this basis.
