Abstract

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.

采矿与降雨耦合作用下岩溶山体失稳机理研究

中国西南地区的矿山滑坡严重威胁着人们的财产和安全。为了研究采矿与降雨耦合作用下岩溶山体的失稳与破坏机理，我们以贵州省麦地煤矿山区滑坡为基础，结合野外调查，分析了滑坡的特征，研究了山体基岩承载结构的稳定性、矿物成分的组成和岩石的微观特征，模拟了煤层的开挖和降雨的渗透。研究了采矿应力和降雨渗透耦合作用下岩溶山体的失稳机理。所获得的岩溶山体在采矿和降雨耦合作用下的失稳和破坏机理为岩溶滑坡的控制奠定了基础。

期刊介绍： Engineering geology is defined in the statutes of the IAEG as the science devoted to the investigation, study and solution of engineering and environmental problems which may arise as the result of the interaction between geology and the works or activities of man, as well as of the prediction of and development of measures for the prevention or remediation of geological hazards. Engineering geology embraces: • the applications/implications of the geomorphology, structural geology, and hydrogeological conditions of geological formations; • the characterisation of the mineralogical, physico-geomechanical, chemical and hydraulic properties of all earth materials involved in construction, resource recovery and environmental change; • the assessment of the mechanical and hydrological behaviour of soil and rock masses; • the prediction of changes to the above properties with time; • the determination of the parameters to be considered in the stability analysis of engineering works and earth masses.
