中文摘要:

贵州煤矿区地质环境复杂，煤矿开采是诱发灾难性地质事件的源头之一。为摸清贵州煤矿地下开采引发滑坡灾害的分布特征，本文通过大量野外调查和数据分析，系统总结了贵州山区采煤诱发滑坡灾害的发育特征和分布特征，结果表明:(1)贵州省含煤地层包括10个地层组，以贵州西部龙潭组产煤最为丰富；(2)贵州复杂山区采煤诱发的滑坡灾害共计375处，显示出以小型、中型灾害为主(合计占比909%)的发育特征，主要为基覆界面发生的浅表层滑动破坏，高陡斜坡区域的大型、特大型深层岩质滑坡较少(合计占比91%)；(3)贵州西部六盘水市(134处)、黔西南州(84处)、毕节市(78处)等区域是采煤诱发地质灾害发育严重地区，其中发育数量最多的是盘州、水城、晴隆等区县；(4)贵州采煤诱发的滑坡灾害主要分布于龙潭组、飞仙关组、长兴组、夜郎组、嘉陵江组等地层，其中龙潭组煤层开采诱发的滑坡灾害占所有采煤诱发滑坡总数的925%。

英文摘要:

The geological environment in Guizhou’s coal mining areas is complex，and coal mining is one of the triggers for catastrophic geological eventsTo clarify the distribution characteristics of landslide disasters induced by underground coal mining in Guizhou，this study systematically summarizes the developmental and distribution patterns of mining-induced landslides in the mountainous areas of Guizhou based on extensive field investigations and data analysisThe results show that:(1)The coal-bearing strata in Guizhou Province comprise 10 stratigraphic groups，with the Longtan Formation in western Guizhou being the most abundant in coal production；(2)A total of 375 landslide induced by coal mining have been identified in the complex mountainous areas of Guizhou，demonstrating a developmental characteristic dominated by small and medium-scale disasters(collectively accounting for 909%)These are primarily shallow surface sliding failures occurring at the bedrock-overburden interface，while large and extremely large deep-seated rock landslides in high-steep slope areas are relatively few(collectively accounting for 91%)；(3)The most severely affected areas are located in western Guizhou，specifically Liupanshui City(134 landslides)，Qianxinan Prefecture(84 landslides)，and Bijie City(78 landslides)Within these areas，districts and counties such as Panzhou，Shuicheng，and Qinglong recorded the highest number of landslides；(4)The mining-induced landslides in Guizhou are primarily distributed in strata including the Longtan，Feixianguan，Changxing，Yelang，and Jialingjiang FormationsNotably，landslides induced by coal mining in the Longtan Formation alone account for 925% of all recorded mining-induced landslides
