摘 要: 介绍了峰峰矿区梧桐庄矿的热水条件,分析了地热引起的热水条件对岩溶发育的影响,最后得出以下几点认识:梧桐庄矿岩溶是在马家沟组硫酸盐-碳酸盐岩混合建造的基础上形成的;梧桐庄矿区热水的来源可能主要为深部循环的热水;地下高温,特别是距离火成岩体近的区域,灰岩的溶解速度快,岩溶陷落柱发育;指出了热水条件对岩溶陷落柱的影响主要包括3个方面:地温异常的对流作用、地球化学作用和“烟囱”效应。
关 键 词: 水文与水资源工程;地下水内循环;热水;岩溶陷落柱;梧桐庄煤矿

Abstract: This paper introduces the Wutongzhuang’s hot water condition of the Fengfeng mining area, and analyses the influence of the hot water on the derelopment of the karst sinking column. Finally is the following understandings are proposed. The karst is formed on the basis of the mix building of carbonate and sulphate; The hot water source of Wutongzhuang coal mine is mainly the deep circulating hot water. Due to the underground heat, especially near igneous rock body, the dissolution speed of the limestone is fast, and the karst collapse column developes. This paper indicates that, the hot water conditions influence the karst collapse column mainly from three aspects: the convection which is caused by the geothermal anomaly, geochemical function and “chimney” effect.
Key words: hydrology and water resources engineering; inner circulation of groundwater; hot water; karst collapse column; Wutongzhuang coal mine
