摘要：Mining landslides in southwestern China pose a serious threat to people's property and safety. In order to study the destabilisation and damage mechanism of karst mountains under the combined action of mining and rainfall, based on the landslides in the mountainous area of the Maidi Coal Mine in Guizhou Province, and combining with field investigations, we have analysed the characteristics of the landslides, investigated the stability of the bearing structure of the bedrock of the mountain, the composition of the mineral components, and the microscopic characteristics of the rocks, and simulated the excavation of the coal seams as well as the infiltration of the rainfall. The destabilisation mechanism of the karst mountain under the coupling of mining stress and rainfall infiltration was investigated. The obtained destabilisation and destruction mechanism of karst mountain destabilisation under the coupled action of mining and rainfall lays the foundation for the control of karst landslides.
