Simulation Experiment Study on Infrared Radiation and Acoustic Emission Feature of Marble Water Inrush
Using marble as experimental material,simulating mine tunnel water bursting with water pressure and no water pressure.In the process of experiment,we use the AE system and infrared thermography to record AE and infrared information of the experiment process real-time.The experimental results show that IR radiation of the samples surface regularly varies with the load.The IR radiation shows an overall rise in early term,then partial high temperature in medium term,and partial low temperature in late term.Analysis of acoustic emission data use relative strength-weakness characteristic.Under the condition of water pressure,seepage usually occurs in the rising stage of index,water bursting is mainly in the declining stage of index,and there will appear a wave crest between two indexes.Under the conditions of water pressure,the time of seepage is longer and the drop range of temperature is lower than that with no water pressure.The experimental results are useful for the early warning of water bursting in the tunnel.
