摘要 六枝矿区是我国南方煤矿水害严重地区之一。本文以六枝矿务局四角田煤矿二水平主斜井绳孔道岩溶突水事故为例,详细介绍该煤矿三叠系下统夜郎组灰岩地层的岩溶分布特征以及岩溶突水对矿山安全的威胁,通过生产实践,对水文地质、工程地质条件复杂的矿井,提出防治岩溶水的措施,可供矿山勘探、建设借鉴,以确保矿井安全生产。 Liuzhi Coal Mine is one of the areas in South Chica where karst water harm is serious. Taking for example the inrush karst water accident in the main inclined well rope pass on the second plane in the Sijiao Coal Field of Liuzhi Bureau of Mining Affairs, this paper introduces in detail the limestone strata of Yelang Formation of the Lower Series of Triassic System in Western Guizhou, karst distribution features and their law, the threat caused by the inrush karst water to mine safety and lessons drawn from the accident. Through production practice, the paper puts forward some experience and methods which can be used in mining exploration and construction to prevent water harm happening in mine wells where hydrogeological and engineering geological conditions are complicated.
