The key technology of fully mechanized caving mining in flammable coal seam with large inclined angle and extra hard roof was researched. The working face adopted positive inclination arrangement,the roadway arranged along the coal seam floor,and deep-hole blasting presplitting method and hydrofracture technique were adopted to control the roof. ZF5600/1 6/28 chock-shield hydraulic supports were adopted,which had powerful side thruster and base adjust-ment device with two jacks,the jacks could run independently. The the technology of anti-skid and anti-collapse applied in working face was reasonable and effective. Practice showed that the working face advanced 4 production cycles and 3.2 m per day,and the test recovery reached 86.76%,this research achieved preferable economic and social benefits.
