Simulation Study On The Stabilation Of Wall Rock About Active Laod

This paper is based on finite element mechanics, calculation mechanics and dynamics knowledge, combine the mine and country rock closely with the dynamics numerical simulation in conformity with the force field, destruction to mine and country rock course set up various kinds of mechanics models research and analyse separately. Mechanics mechanism go on research to exploit course lead water crack is it change to take, and with move function to is it quarry empty district country rock stress place change compare to go to the fields year. Dynamics respond the characteristic, on the basis of surveying the materials to analyse and research to the scene, obtain geometry parameter is it cover rock lead water crack with development change characteristic and under the influence of dynamics loads of country rock kinetic respond to influence.Utilize ANSYS finite element advantage to analysis software, set up planer and three-dimensional model cover to spread characteristic and working range geometry parameter that fluctuate rock lead water crack bring height exploiting, range, country rock must person who change all influence of carry on research in conformity with force field. Carry on statics and dynamics analysis, finally in combine theoretical research, scene survey materials, it is summarize for finite element simulation research results, get country rock lead in conformity with change of force field to country rock stability influence and corresponding terms fluctuate spread characteristic. And on the basis of calculating the single lane , one pair of lanes and three lanes of models , have done systematic studying to the impact of the underground structure to the load of moving , quality of the model in different cases. It all have directive significance that the research contents of this text are practiced to the theoretical research or the project.
