Sharp Inelined Deposit Deep Mining Strata Movement Rules Research

This paper with sharp inclined deposit deep engineering at YinMuSi, through deeptypical conditions of mechanical properties of rock mass uniaxial test and the determinationof triaxial test, determines the mechanical parameters of rock; and by the field Windowsobservation method based on statistical analysis of geological mechanics, international rockmechanics classification method, has carried on the deep rock mass structure classification.The analysis parameters computational expressions and mass strength criterion of deep rockare given, through the establishment of the 3D geological mechanics model for the wholemine, the initial geostress distribution and mining stress distribution of history stressdistribution are obtained and further establish mining calculation model to analyse 30 metressection and 60 meters high mineral room rock plate section deformation movement rulesunder the influences of mine mining, ore filling and putting ore process such technologyprocesses. Through the ultrasonic observation, studies the surrounding rock ore room spikedestruction rules caused by deep pressure,discusses the damage mechanism of deep deliveringhigh surrounding rock ore room stope. Finally, this paper puts forward the mining parametersand surrounding rock anchorage parameters matching the deep mining of surrounding rockcontrol at YinMuSi according to the results. Field test results show that the paper resultsprovide scientific basis of YinMuSi mine deep mining, success in solving the deep miningproblems at YinMuSi.
