摘要

在深褐煤开采区域发现了三个酸性水泉，该开采始于2014年的ČSA露天矿(Albrechtice靠近Most地属)。一根弹簧(jz163)直接从探井的套管流出，在坑道底部略高的地方切割。另外两个源(CH1和CH2)是直接在煤层中的泉水。泉水为Na-HCO3 (jz163)、Na-HCO33-SO4 (CH1)和Na-Ca-SO4-HCO3 (CH2)水化学类型。它们的总矿化在2.3 ~ 2.8 g/L之间，温度高达29.1℃。在所有情况下，泉水都伴随着大量的二氧化碳流出。所描述的产状属于Krušné hory Mts. (Erzgebirge Mts.)下酸性水体的北部带，连接了沿Eger裂谷的Klášterec、Ohří和Bílina碳酸水的重要位置。该矿于2020年4月27日关闭，该地点已无法进入。

Report on the occurrence of the acidulous waters below the final slope of the ČSA open-pit (Most Basin)

Three springs of acidulous water were found in the area of the deep lignite mining, which began in 2014 in the ČSA open-pit (Albrechtice near Most cadastre). One spring (JZ 163) flowed directly from the casing of the exploratory well, cut slightly above the adit floor. Two other sources (CH1 and CH2) were springs directly in the coal seam. The springs represent Na-HCO3 (JZ 163), Na-HCO33-SO4 (CH1) and Na-Ca-SO4-HCO3 (CH2) hydrochemical type of waters. Their total mineralization varied between 2.3 to 2.8 g/L and the temperature was of up to 29.1 °C. In all cases, the springs were accompanied by massive CO2 outflows. The described occurrence belongs to the northern belt of the acidulous waters underneath the Krušné hory Mts. (Erzgebirge Mts.), linking the important localities of carbonated waters in Klášterec nad Ohří and Bílina located along the Eger Rift. The mine was closed on 27 April 2020 and the site is no longer accessible.

期刊介绍： Geoscience Research Reports inform the general public about current state of knowledge in a wide variety of geologic subjects. Here the reader will find the results of research conducted by the academia, by the public as well as private sectors. The articles are distributed into individual science topics – regional geology, stratigraphy, Quaternary research, engineering geology, paleontology, mineralogy, petrology, geochemistry, hydrogeology, mineral resources, geophysics, geological information system and international activities.
