摘　　要：同类型水体下防水煤岩柱的留设问题一直是采矿工程中研究的热点.在分析淮南煤田潘集矿区、淮北煤田兴隆庄矿区、兖州煤田百善矿区的水文地质条件及突水实例的基础上,针对Ⅰ类采动等级水体下留设的防水煤岩柱不能确保安全生产问题,探讨了含水层承压与Ⅰ类水体下防水煤岩柱的留设问题,提出了相关建议.The problem of setting up the height of water- prevention coal- rock pillar under the same water body has always been the hotspot in mining engineering. According to the hydrogeological condition and the water inrush examples in Panji,Huainan coal mine area,Xingrongzhuang,Huaibei coal mine area and Baishan, Yanzhou coal mine area,analysis results show that the height of water- prevention coal- rock pillar under water body of classⅠsometimes can＇t ensure safety in production. Therefore,some suggestions for water- prevention coal- rock pillar under water body of classⅠ are presented by considering the factor of water pressure,which can provide reference for remaining the height of water- prevention coal- rock pillar in mining engineering and also provide safety in production.
