摘要
文中详述了湖南恩口煤矿近20平方公里范围内,在大于700米深孔中开展地下水示踪的条件,技术和取样方法。采用新示踪剂钼酸铵,并对高、低不同浓度的钼样品进行比色法和示波极谱法分析。根据26个取样点的分析结果表明:恩口煤矿Ⅰ、Ⅱ井田间存在一分水岭及该区主要断层周家岭断层深部为一导水断层。上述结果为该矿深部采掘设计提供了重要资料。
Tracing of ground water is an effective method to reveal hydraulic connections between various groundwater systems. This paper gives a detailed description of the tracing condition, technique and sampling method in deep holes of more than 700m within an area of 20km2 of the Enkoy Coal Mime, Hunan province. New tracer ammonium molybdate was used and samples with high or low concentration of molybdenum were analyzed by means of colorimetry and polarography. The analyses of samples from 26 sampling points indicate that there is a watershed between coal mines Ⅰ and Ⅱ. and the major fault of Chouchailing in this area is a water-transmitting fault at depth. The above - mentioned results provide important information for the design of deep mining of Enkou Coal Field.
