Investigation on Fully Mechanized Mining Technology of Thin Coal Seam under the Near Goaf

Abstract:

With the resources exhaustion of medium-thick and thick coal seam, the mining technology of thin coal seam has attracted more attention. Due to the little working space for mining in thin coal seam, blasting mining and high-grade conventional mining are main mining methods that were used in thin coal seam. Taking the 17^th coal seam of Liyan mine as an example, in this paper we analyze the roof structure of the lower thin coal seam under the goaf of the upper coal seam. The fully mechanized mining equipment is selected on the basis of the new roof structure and applied in field. Finally, safe and efficient mining is achieved by improving the adaptability of the equipment.
