Abstract: The problems of roadway support and pillar loss exist in thick coal seam mining in China. In this paper, the main research content is the full-thickness mining method of staggered roadway layout in thick coal seam, which is solved by comprehensive recovery ratio and roadway support. Firstly, full-seam mining adopted roadway layout of stagger arrangement in thick coal seam is introduced, on this basis, the process characteristics of the uphill section are proposed. Secondly, combined with the characteristics of gob-side entry driving, the skip mining characteristics of this technology are proposed. Based on the classical theory of roadway layout, the mechanism of staggered roadway layout and roadway bearing characteristics are determined, so as to eliminate the problem of isolated coal pillars caused by skip-mining and achieve the maximum recovery ratio of the working face. Finally, the application of the mining method is introduced according to two typical characteristics of mines. It is found that this mining method has unique advantages in recovery ratio, spontaneous combustion seam and roadway maintenance.
