摘　　要：近年来,煤矿生产受底板灰岩水影响而导致水害事故频发。本文从水文地球化学的角度,以刘桥二矿太灰上段1-4灰水样为研究对象,利用CO_2-H_2O平衡系统,对水样中的碳酸盐矿物的溶沉情况进行计算分析,最后得出:刘桥二矿水样中碳酸盐多为沉淀状态。该结论表明该矿区地下岩溶水排泄不畅,致使地下水中溶解盐类增多、二氧化碳、氧气等气体耗尽,最终丧失溶解能力。该结论对相似矿区防治灰岩水提供参考价值。In recent years, water disasters accident frequently caused by limestone water. From the perspective of hydro geochemistry,taking limestone layers（ L1-4） of Taiyuan Formation at Liu Qian coal mine as research object,this paper calculated and analyzed solution-precipitation of carbonate minerals using CO_2-H_2O balance system. Finally it concluded that water samples are mostly supersaturated, namely precipitation state. The conclusion shows that underground karst water has drainage difficulty and increases dissolved salts in groundwater,meanwhile carbon dioxide, oxygen and other gas are exhausted, which eventually lose ability to dissolve. The conclusions provide reference value for prevention and control of limestone water of similar mine.
