Abstract: Taking the 8311 working face of Tongxin Coal Mine as a study case, practical research on small coal pillar mining
technology was conducted. A study was conducted on the control technology scheme of rock pressure manifestation in the 8311
small coal pillar working face, and a comparative analysis was conducted on the rock pressure manifestation of small coal pillar
mining technology and large coal pillar mining technology. The results show that the application of small coal pillar mining
technology in the 8311 working face has achieved good results in the treatment of mining pressure in goaf tunnels and the
improvement of resource recovery rate. It effectively controls the deformation of surrounding rock in goaf tunnels, reduces the
occurrence of mining pressure accidents such as roof fall and slope fragmentation, and has good safety and economic benefits.

Key words: extra thick coal seam; strata behavior; small coal pillar mining; large coal pillar mining
