Chinese coal output from full-mechanized mining has increased 59 times and maximum output of a full-mechanized mining face has increased 28 times since China started reform and opening-up. Full-mechanized mining with large mining-height in softly inclined coal seam made big progress; full-mechanized caving mining and equipments developed fully; full-mechanized and high-grade conventional mining equipments in softly inclined thin and medium-thick coal seam have developed and output has increased several times over; mining methods under special conditions have gained Chinese characteristic.
