Study On Mining Method Of Honeycomb Cemented Filling In The East Lean Ore Of Jinchuan Mining Area

The study of poor ore mining in the eastern part of Jinchuan Mining Area is related to the economic feasibility of the lean mining in Jinchuan,and it is one of the key points for Jinchuan to become stronger,bigger and better and develop with high quality.In this paper,by conducting jinchuan east lean ore mine geology,ore deposit geology,rock mechanics and mining area resources such as initial investigation and study,combined with honeycomb structure cemented filling mining method to determine process parameters of extraction,using ANSYS software and FLAC^3Dcoupling modeling complete original rock stress,mining-filling sequence,stope parameters,such as numerical simulation,the regional stress,strain and displacement,plastic zone,the strength of filling body key parameters,such as to determine the best extraction design solutions and put forward the construction of cohesion,mining and the technical economy and production capacity analysis.Through the research and application of honeycomb cemented filling mining method,the poor ore resources in the east of Jinchuan mining area can be safely and scientifically mined,and the technical problems that need to be solved for the mining of thick and large deposits with broken rocks and poor stability in underground non-ferrous metal mines in China can be better solved.
