| 摘 要： | 通过对抚顺老虎台矿区各类水体的同位素及水化学特征研究,阐述了地表水与矿井各开采水平及73003#突水点的同位素和水化学特征及其相互关系,论证了矿井上覆白垩系砾岩含水层与73003#突水点的联系。研究表明：73003#突水点的同位素及水化学特征与地表水及其他开采水平差异较大,而与白垩系砾岩水的同位素及水化学特征相似。根据同位素、水化学特征及混合计算发现,突水点的水是白垩系地下水与第四系地下水的混合,且白垩系砾岩水占67%,占主导作用;矿井突水通道为活化的F1断层。

| Abstract: | Isotope and hydrochemical features of various types of water bodies in Laohutai mine were studied.Isotope and hydrochemical features of surface water,all mining levels of the coal and water bursting site 73003# were represented,and the relationship between Cretaceous conglomerate aquifer above the mine and water bursting site 73003# was discussed.The results showed that isotope and hydrochemical features of water bursting site 73003# were different with surface water and all mining levels of the coal,but similar to Cretaceous conglomerate aquifer.According to isotope and hydrochemical features and theory of mixed water,water in the water bursting site was mixed by Cretaceous and Quaternary groundwaters,and Cretaceous groundwater was the main source and accounted for 67%;channel of water bursting site was activate F1 fault. |
