Practice and Application of Different Supports in Mining Process of Thick Coal Seam
Improving the recovery rate of coal resources and the production efficiency of raw coal is an important index to measure the high-quality development of coal enterprises,and adopting fully-mechanized top coal caving technology for thick coal seam is the only choice at present.Two sets of top coal caving mining equipment in the geological conditions,production efficiency,safety control and roof management,as well as the support sliding and falling accidents were analyzed,and the direction of selecting the appropriate top coal caving mining equipment under the same coal seam and geological conditions was put forward.
