同位素示踪技术在潘北矿太原组灰岩水水化学特征中的应用

Isotope Tracer Technique in Tanbei Mine of Taiyuan Group Limestone Water Chemical Characteristics of the Application

潘北矿深部煤层开采工作面突水水源主要来自第四系松散层水、煤层上覆顶板砂岩裂隙水和下伏底板太原组石灰岩水、奥陶纪和寒武纪白云岩水。为了探讨太原组石灰岩水与其它水体之间的水力联系。采集潘北矿主要含水层水样品25件,采用MAT 253同位素质谱仪测试样品中氢氧同位素值,研究结果表明:(1)太原组石灰岩水主要表现为三种水质化学类型;(2)太原组石灰岩水的氢氧同位素含量差别较大;(3)太原组石灰岩水的主要补给源为地表水体和深部古水。

the deep coal mining working face of panbei mine water inrush water mainly from quaternary loose bed water, coal seam overlying roof sandstone fissure water and underlying base plate of taiyuan group limestone water,ordovician and Cambrian dolomite. In order to explore of taiyuan group limestone hydraulic connection between water and other water bodies.This paper collected the main aquifer water samples of 25 pieces of panbei mine,the MAT 253 hydrogen and oxygen isotopic values in the isotope mass spectrometer test samples,the results showed that：（1）of taiyuan group limestone water main performance for three types of water quality chemistry;（2）the difference of content of hydrogen and oxygen isotopes of taiyuan group limestone water; （3） the main supply source of taiyuan group limestone water to the surface water and deep water.
