Abstract

This paper researched underground pressure behavior rule and characteristic of full-mechanized caving mining face with soft roof,soft coal and soft floor by theoretical analysis of movement rule of surrounding rock and mechanics relationship of powered support and surrounding rock.Results may be used to instruct solving actual problems in full-mechanized caving mining coal seam with soft roof,soft coal and soft floor.
