The breaking of hard and thick key layers can easily cause dynamic disasters, such as rock burst mine seismicity, seriously threaten safe mining. To analyze the characteristics overburden breakage law evolution separation cracks under mining stratum, to further reveal process occurrence disaster, fracture overlying strata during were analyzed via similar simulation in this study. surface movement deformation before after then discussed based on displacement. Finally, development fissure...
When the hard and thick key strata are located above working face, bed separation structure is easy to be formed after mining because of high strength integrity initial breaking step large. After hard, broken, overburden will largely collapsed unstable in a large area dynamic disaster easily induced. In this study, considering fundamental deformation failure effect coal seam, development law fractures under magmatic rocks mechanism induced studied by similar simulation tests. The results...
In order to study the effect of stress and water pressure on permeability fractured rock mass under three-dimensional conditions, a single fracture triaxial stress-seepage coupling model was established; By using true test system, large-scale specimens were taken as research object carry out seepage, fitting formula coefficient obtained. The influence discussed. results show that have significant coefficient, showing negative exponential relationship. Under certain decreases with increase...
Quantification of the influence fracture thick magmatic rock (TMR) on behavior its overlying strata is a prerequisite to understanding deformation earth\'s surface in deep mining. A three-dimensional numerical model special geological mining condition TMR was developed investigate overburden movement and law, compare occurrence horizon TMR. The research results show that greatly affected by Before TMR, had shielding controlling effects strata, maximum vertical horizontal displacement values...

Abstract A numerical time-dependent model is established by incorporating the stress corrosion into three-dimensional discrete element grain-based (3DEC-GBM) to analyze fracture evolution and instability mechanism of surrounding rock mass around a circular tunnel. The tunnel assumed be made from intact Yunnan sandstone formation, whose material properties were found using laboratory experiments (ignoring scale effects). mesoscale mechanical parameters in are calibrated reproduce...
