Abstract: Currently, the resource recovery rate in large coal mines in China is approximately 65%.Compared with the recovery rates in developed countries, the wastage of coal resources is significant.Therefore, it has become imperative to enhance research on new mining technologies.There is an urgent need to adopt efficient and high-recovery coal mining techniques to improve the recovery rate of coal in mines.In coal mining processes, the retaining of coal pillars results in substantial losses of coal resources.Thus, selecting a reasonable coal pillar width and employing small coal pillar gob-side entry driving or gob-side entry retaining without coal pillars are crucial for conserving coal resources.This paper conducts a theoretical analysis of the reasonable width of small coal pillars for the ZF2822 working face in the Xiagou Coal Mine.
