Based on theoretical analysis, numerical simulation and field experimentation, and the physical and mechanical feature of 6-2 coalseam roof strata，the caving feature of roof coal was well analysized and the possibility of full seam mining in thick coal seam was studied. Also, the mining technics, recovery and economy benefit of inclined seam with full seam extraction mining were studied and analyzed at all. Firstly, according to the anaysis of the condition of enlarging hoisting ability and coal production, the problems existed in slicing mining, the adventage of full seam mining in Chenjiagou Coal Mine, it was nessary to use full seam mining method. Through the evaluateon of caving condition of 6-2 coalseam and numerical calculateion, the feasibility of full seam caving mining was demonstrated, and the method of roof coal weaken was put forward. By filed test in 3101 face, the entry system, equipments, face supporting, caving technics, excavation and technics were systematacially improved, and the way to improve coal recovery was put forward. Finally, by field observation, the ground pressure of mining face was discovered, and the ground control way was educed. According to research, the extrude problem of especially thick coal seam mining method in 22m thick inclined seam in Chenjiagou Coal Mine were well solved. Furthermore, the other problems that condition coal mine development were also solved, such as the strained condition of driving and mining, the over large ground pressure of entries, low recovery, low work efficiency and benefit. According to the application of this research, the single face output was rised to 1.5Mt/a，coal recovery got 85%, work efficiency was 40t/w, and high production and high efficiency face was achieved. This research can improve whole mine production and will have good impact on local economy improvement. This research work will show a new way to construct high-production and high-efficiency coal mine, and will use for good reference to Yaojie and Jinyuan coal mining field.
