充填体应力监测方法及研究进展

AbstractMining industry has provided a solid material foundation for the development ofhuman society,and is of great significance to the healthy development of the nationaleconomy.With the completion of the mining of shallow surface resources,underground mining is the inevitable trend of the development of mining industry,butwith the progress of underground mining,the treatment of goaf has gradually becomea big problem.The filling method can well deal with a large number of tailingsproduced in the mining process.A large amount of solid waste will be produced in theproduction process and mineral processing stage of mines,which will occupy landresources and destroy the ecological environment.The rational utilization of tailingsis an important measure to promote the recycling of mine resources and achieve"carbon neutrality".This paper mainly studies the theory of filling hardening and filling stressmonitoring system,analyzes the reliability of frontier technology,and discusses theprogress of filling stress monitoring.This paper summarizes the current filling stress monitoring method and researchprogress at home and abroad,the main research content is the stress monitoringmethod of filling,mainly considering the change and distribution law of filling stress,and summarizes the shortcomings of the filling stress monitoring method and theresearch status of filling stress monitoring at home and abroad.The solution of theexisting problems cannot be separated from the research and innovation of the stressmonitoring methods,and the stress monitoring of the filling body will be the focus ofa lot of theoretical and practical demonstration in the future.Key words:filling body;stress monitoring;stress analysis;numerical simulation
