An integrated method to calculate the spatial distribution of overburden strata failure in longwall mines by coupling gis and flac3d... The results of case study show that the height of the fractured zone reached the maximum value at the face advance equal to about the panel width....
Research on movement and deformation of rock strata between coal seams in pillar upward mining of left-over coal with numerical simulation method... mining process was numerically simulated by FLAC3D,the variation law of displacements field on interlayer strata between the 6th coal seam and the 8th coal seam at different face advance were analyzed....
Interaction of periodic system heterogeneous inclusions and cohesive cracks under longitudinal shear... The analysis of cracks limit equilibrium using the end zone model is performed based on nonlocal fracture criterion with force condition of the crack tip advance and deformation condition for determination of the crack end zone face advance
Analysis of insidious fault activation and water inrush from the mining floor... Results indicate that during the whole working face advance, transpressions are exerted on fault planes twice successively in opposite directions....
