中文摘要：

通过对贵州猴子沟煤矿区进行水文地质调查与水样采集、测试、分析,揭示了岩溶管道水文地质、水岩反应以及硫、氧同位素特征。研究结果显示,地表径流、大气降水以及酸性矿山水多种端元水混合后通过落水洞进入岩溶管道与管道水混合,管道水在岩溶管道内径流通畅,流速较快,最终排泄到地表河流中。大气降水与泥盆系上统的碳酸盐岩接触,其携带的H~＋在入渗过程中与碳酸盐岩发生水岩反应,形成Ca（Mg）-HCO_3型水;黄铁矿在开采巷道内氧化与巷道水形成硫酸,向水中进一步释放SO_4^2-和H^＋,使巷道水pH进一步降低。巷道水同位素分馏作用强烈,轻同位素被利用,重同位素被留下,形成δ^34SSO_4值＋1.24‰,δ^18OSO_4值＋2.54‰的偏正同位素特征值。酸性矿山水通过落水洞进入岩溶管道,管道水流通顺畅,流速较快,微弱的分馏作用使得δ~（34）SSO_4值仅升高＋0.05‰。

英文摘要：

Based on the hydro geological investigation of Guizhou coal mining area and collecting,testing and analyzing water sample,the hydro geological,water rock reaction and sulfur and oxygen isotope characteristics of karsts pipeline are revealed,research results show that already mixed. Surface runoff,atmospheric precipitation and acid mine water through the hole enter into the karsts pipeline to mix pipeline water. in karsts pipeline water that eventually discharged to the surface of the river is unobstructed and rapidly flows. Atmospheric precipitation touch carbonate rocks in Devonian System and H ＋ in it water rock react with carbonate rocks in the infiltration process to form Ca（ Mg）-HCO_3 type water. Oxidized pyrite in mining roadway and tunnel water formed sulfuric acid and it further release SO_4~（2-） and H~＋ into water to further reduce the roadway water PH. The water isotope fractionation of the roadway is strong,the light isotope is used,and the heavy isotope is left to form the positive isotope characteristic value of the δ~（34）SSO_4 value and ＋ 1. 24 ‰,δ~（18）OSO_4 value and ＋ 2. 54 ‰. The acid mine water enters the karsts pipeline through the water hole. The pipeline water flow is smooth,the flow rate is fast,and the weak fractionation makes the δ~（34）SSO_4value only increase ＋ 0. 05 ‰.
