| 为宏观判断茅口组古岩溶地下水对煤矿开采的影响，从茅口组石灰岩沉积环境、古岩溶发育环境的研究角度，采用印模法等总结了中晚二叠世沉积演变模式，分析了东吴运动、玄武岩热液、古地貌等因素对茅口组石灰岩古岩溶发育的影响，并据此对茅口组古岩溶发育程度以及古岩溶地下水对煤矿开采的水患影响程度进行了分区。研究结果表明贵州省内茅口组古岩溶发育程度具有由南西向北东逐渐减弱的趋势、茅口组顶部古岩溶带中赋存的地下水对煤矿开采的影响程度则具有从西向东增大的特征。 |

| In order to judge the influence of the palaeokarst groundwater on coal mining in Maokou formation macroscopically，in the paper，from the perspective of the sedimentary environment of Maokou limestone and the development environment of the palaeokarst，it used the imprint method and others to summarize the sedimentary evolution model of the middle and late Permian，and analyzed the influence of the Dongwu Movement，basaltic hydrothermal fluid and ancient top on the development of the palaeokarst in Maokou limestone Accordingly，the development degree of the palaeokarst in Maokou formation，the degree of waterlogging hazard of the palaeokarst groundwater to coal mining were zoned The results of the study show that the development degree of the palaeokarst in Maokou formation in Guizhou has a trend of gradually weakening from the southwest to the northeast，but the impact degree of the groundwater in the karst zone at the top of Maokou formation to coal mining has the characteristics of increasing from west to east |
