Study on deformation zoning of overlying strata and simulation of rock pressure behavior in longwall top coal caving mining

At present, longwall top coal caving (LTCC) mining is main mining method for safety and efficiency mines with extremely-thick coal seam in China. However, the deformation movement law of overlying strata on LTCC face directly affects rock pressure behavior of LTCC face, selection of hydraulic suppor...
