Study on infrared time-space evolution features of water inrush process in mine soft rock roadway heading

Aostact : n order to get theinfrared tine-space evolution features of the waterinrush process of soft rock roadway heading face and to provide certain theoreticalbase to the time-space predicton and remote sensing monitoring and measuring on water inrush acident during the excavatio procss of the mine actial ngineeringroadway and the water leakage of the tunel.the paper had a studyon the inirared radiaton features ofth silistone during the water inrush prcess of the biaial fading and the water inrush information were comprehensively predicted and identfied from the time-space factors The testresutis showed that 1 based on the size of thewater inrush.the water inrush evolution proc.ss ofthe siltistone was divided in to seepage → drioing water → water soray -= water inush fou steps 2 the infrared radation temperature curve features of th silistone water inrush was indidually dfferent at each diferent stage.,the temperatre rising raidly wauld be a precusorof thewater inrush voume increased and a suden rising or a sudden dropping of a min radiaton temperature would be a predicted warer inush ocured; 3 during the loading process a igh temperature abnomal zone would be the location ofthe seepage occured and wouid be the fimal warer inorsh location.Before abut 10 s f the seepage occurred,the related seepage location would have an abnormal high temperature. After the seage oc.urred,the abnormal nigh temperature would be changed toan abnormal low temperature and with the water volume increased,the temperature reduction would be highly reduced An infrared thermal imager was applied to study the water nrush identfcation and the mornitoring and measuring prediction from a view of the tinme-space comprehensive predction.On a ceran dege.thelos by thewater inrush accident could be reduced in the actual engineering project.
