The researchers made great breakthrough in the theory and technology of exploitation for thick and extra thick coal seam, created the loose medium flow field theory in full-mechanized top coal caving mining, and based on the control of roof and coal wall, established the new method in the surrounding rock control of thick coal seam. Besides, with the collaborations with the coal enterprises, the researchers developed the extra thick coal seam full-mechanized top coal caving mining technology with a great mining height of more than 14 meters, the 60°thick coal seam  long-wall full-mechanized mining technology, the mining technology of fully-mechanized coal mining with large mining height in thick coal seam with large buried depth, thin bedrock and potential water risk, and other efficient exploitation technologies for complex thick coal seam, and invented fault layer mining method of thick coal seam and three stage mining technology, successfully solving the technological problems in efficient and safe mining of China’s thick coal seam.
