峰峰矿区奥灰水中氢氧同位素漂移特征分析
|
摘要
为了综合评估采煤驱动下奥灰水中氢氧同位素的漂移特征,本文分别采集了峰峰矿区不同径流区的奥灰水样品27件,通过分析氢氧同位素D和18 O的漂移特征和水-岩作用,阐明了其漂移过程。研究结果表明:煤矿开采后,南部径流区,奥灰水中的氢氧同位素组成呈背景特征,未发生漂移现象;东部径流区,同位素D漂移现象显著,漂移率为57.14%,部分样品D和18 O双项漂移;北部径流区,同位素D和18 O双项漂移明显,漂移率为27.27%;同位素D漂移与奥灰水和硅酸盐矿物的水岩反应有关,水-岩相互作用中伴随有同位素D的交换平衡反应;同位素18 O漂移与奥灰水和碳酸盐矿物的水岩反应有关,水-岩反应伴随有同位素18 O的交换平衡反应;D和18 O的双项漂移现象的发生则是奥灰水与碳酸盐和硅酸盐水-岩反应共同作用的结果。
In order to comprehensively evaluate the drift characteristics of hydrogen and oxygen isotopes in the Ordovician Karst groundwater under coal mining,this paper collects 27 samples from different runoff areas in Fengfeng mine area,analyzes the drift characteristics of D and 18 O isotopes and clarifies its drift process.The results show that in the south runoff areas,the composition of hydrogen and oxygen isotopes no drift with background feature after strongly coal mining;in the eastern runoff area,the isotope D drift remarkable,the drift rate 57.14%,and simultaneously some samples D and 18 O drifted together;in the north runoff area,the isotope D and 18 O drift obvious,the drift rate 27.27%;the isotope D drift is related to the water-rock reaction between Ordovician Karst groundwater and silicate minerals,accompanies with the D drift equilibrium reaction;the isotope 18 O drift is related to the water-rock reaction between OrdovicianKarst groundwater and carbonate minerals,accompanies with the 18 O drift equilibrium reaction;the isotope D and 18 O drift are related to the water-rock reaction between Ordovician Karst groudwater and carbonate and silicate water-rock reactions.
