Study On Deformation And Stability Monitoring Of Goaf In A Manganese Mine

Based on the current situation of ground pressure in a manganese mine goaf,through the investigation and analysis of the ground pressure monitoring system and methods,combined with the actual situation of the mine,the online monitoring scheme of the mine goaf is formulated and the online monitoring system of the mine goaf is constructed.The mine monitors the ground pressure extension in the goaf through the stress on-line monitoring system,monitors the change of rock mass in the goaf through the microseismic on-line monitoring system,and monitors the roof subsidence in the goaf through the displacement monitoring system.Through the operation of mine ground pressure monitoring system for half a year,the applicability of the system in mines is summarized and analyzed,and the safety early warning system of mine goaf is improved.Based on the data collected by the mine ground pressure monitoring system,combined with the actual situation of the mine and the research situation of similar mine goaf,this paper demonstrates the effectiveness and practicability of the system in the practical application of the mine.At the same time,it analyses and summarizes the law of ground pressure development in the goaf of the manganese mine.On the one hand,it solves the practical problems of the mine,effectively guarantees the safety of the mine,on the other hand,it is the same.The disposal of goaf in type mine has good guiding significance.
