ABSTRACT
This paper with sharp inclined deposit deep engineering at YinMuSi, through deep
typical conditions of mechanical properties of rock mass uniaxial test and the determination
of triaxial test, determines the mechanical parameters of rock; and by the field Windows
observation method based on statistical analysis of geological mechanics, international rock
mechanics classification method, has carried on the deep rock mass structure classification.
The analysis putational expressions and mass strength criterion of deep rock
are given, through the establishment of the 3D geological mechanics model for the whole
mine, the initial geostress distribution and mining stress distribution of history stress
distribution are obtained and further establish mining calculation model to analyse 30 metres
section and 60 meters high mineral room rock plate section deformation movement rules
under the influences of mine mining, ore filling and putting ore process such technology
processes. Through the ultrasonic observation, studies the surrounding rock ore room spike
destruction rules caused by deep pressure,discusses the damage mechanism of deep delivering
high surrounding rock ore room stope. Finally, this
