Technology of mine pressure bump regional stress control

in orderto bascally reduce the stress concentration possible to cause the mine pressure bump and to fcively contain the mine pressure bump accdent ocured in China,based on the sinilarsimulation and unmerical simuiation were applied to study the stress afifected to cause the mine pressure bump a regional stress conirol technology to prevent the mine pressure bunp was provided.T'he paper introduced the implementation method of the geostress measurement.3D geologicamechanics modeling inversion of 3D geostress feld and theregional prevention of the mine pressure bump appied in the 'technology.T he technology was appied to themine pressure bunp in Shuangyasan Mining Area based on the practices on the mine pressure bump disaster revention and control with the regional tress contro.The appication resuls showed that with the mine pressure bump prevention and conrol with the regional stress conirol conducted n the mine,with the optimized layoutof the mining blocks,the stress was reduced by 25.8% wWih the sinulation analysis on the stress distriution status in the dynanic mining and heading procss in the underground mine,the mine pressure bump danger area was marked and could set up a good base to prevent and control the late mine pressure bump disaster
