Stent type and relevant major parameters made a difference in safety production of working face. Combining with geological condition of 3-803 working face and coal seam occurrence in this paper, numerical simulation was used to study working resistance and supporting intensity of two mining technique hydraulic support which were mechanized caving and fully mechanized mining respectively. Reasonable structure height of different mining technique hydraulic supports were determined by theoretical calculation and specific parameters of various quantity of pillar support were analyzed as well.
