In order to solve three coal mine under the economic 53下09 full-mechanized caving mining face with more than bottles of the layered with 3下 thick coal seam under the top coal caving mining,raise coal recovery,the site practice and research problems and the way of the combination of the theoretical research on the research and analysis to the theoretical analysis and production site combining practice application is given priority to,for more complex structure with bottles of the thick layer 3 thick coal seam under the 53下09 fully-mechanized sublevel caving of top-coal bottles containing clip at put sex,put coal technology and put the management and optimization of coal way out rules,clip bottles to determine the thickness of limit,and points out that with the activities of the top-coal bottles containing rules and top coal caving mining clip the limit of the gangue thickness,the maximum recovery rate,reduce enhance the coal goaf spontaneous combustion rate,in the actual production of got a very good use of.
