Analysis and Study on the Safety and Stability of Open-pit Slope in Mengku Open-pit Mine and Preventive Measures
This paper mainly discusses the potential collapse and landslide of slope and the influence of debris flow caused by sublevel caving without sill pillar on underground production system and mining operation,it is possible to cause underground mine roof fall spalling,tunnel cave collapse or underground sand-burst,water-burst flooded wells and other accidents.There-fore,in order to ensure the normal production of underground mining in Mengku mine,through field investigation,numerical simulation analysis and theoretical research,the qualitative and quantitative methods are adopted,the safety risks of upper open pit slope collapse,underground debris flow impingement on underground production system and mining operation during the mining period of Mengku mine are analyzed,and the corresponding safety countermeasures are put forward,to ensure the safe,orderly and efficient operation of underground mining.
