摘　　要：通过设置不同的温度梯度,实验模拟梧桐庄矿岩溶陷落柱发育的水环境条件,分析温度对该矿岩溶陷落柱发育的影响。通过测定并对比分析不同组样品的pH和〔Ca2+〕数据,分析温度T对碳酸盐岩和硫酸盐岩溶解的影响,从而揭示热水在梧桐庄矿岩溶陷落柱发育过程中的重要作用。In this paper,the author performed an experiment that simulated the water environment condition at different temperature gradients in Wutongzhuang coal mine in order to analyze the influences on the development of karst collapse column by temperature.Determining and comparative analyzing the pH and〔Ca2＋〕dates of samples in different groups,analyzing the influence of temperature on dissolution of carbonate and sulphate,the author intend to reveal the important function hot-water performs in development of karst collapse column in Wutongzhuang coal mine.
