| 摘 要： | 利用示踪不同含水层水文地球化学特征的标型微量元素捕捉突水预兆期内的水文地球化学信息,建立判别模型分析煤矿重大突水水源,具有重要的理论与实践意义。本课题利用任楼井田及所在临涣矿区其他生产矿井的长观孔、矿井出水点从上而下分别取第四系第四含水层、二叠系煤系砂岩含水层、石炭系太原组岩溶含水层及奥陶系岩溶含水层24个水样,测试了24种微量元素含量。通过分析4类主要突水含水层微量元素含量与聚类规律,得到了Be、Zn、Ga、Sr、U、Zr、Cs、Ba8种主要突水含水层的标型微量元素,建立了以标型微量元素作为解释变量的突水水源Bayes线性判别模型。以24个水样为训练样本,得到模型判别正确率达到了80%,并分析了区域水循环与水文地球化学演化对判别模型效果具有一定程度的控制作用。

| Abstract: | It is of great academic and practical significance that hydrogeological information during the sign time of water bursting is captured by means of standard type trace elements which can trace hydrogeological features of different aquifers. Using the observation bores and mine streaming water in the Renlou mine and the other mines in local Linhuan coal district,24 samples taken from the fourth aquifer of the Quarternary,the coal and sandstone cranny aquifer,the Taiyuan limestone aquifer and the Ordovician li... |
