Abstract：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.
