摘要
Abstract
To investigate the influence range and deformation patterns of the slope of the external dump of the Mao'ergou Open-pit Mine affected by the underground mining face,a simplified engineering geological model tailored to engineering reality is constructed.The theoretical influence range of the underground mining face on the dump site slope is preliminarily defined.By combining the radar displacement cloud map of the slope,it is revealed that there are differences between the slope deformation characteristics and theoretical calculation results.Through numerical simulation and other methods,the deformation mechanism of the slope under the influence of underground mining disturbance is deeply analyzed.The research results show that,influenced by underground coal mining disturbance,the main deformation direction of the slope still develops along the free face.By conducting stability checks on the current slope under different strength reduction conditions,it is found that the advancing distance of the underground mining face and the number of strength reductions are the significant factors affecting slope stability.关键词
