Abstract: Based on the analysis of different roadway support forms used in the coal mine, the relevant research on bolt support
in the extremely soft rock roadway in the coal mine was carried out. This paper introduced the development of roadway support
theory, selected the appropriate technology according to the characteristics of different roadway support technologies, and carried
out the research on roadway support in extremely soft rock. The research results show that the adopted roadway support technology
can improve the roadway support effect, enhance the safety of the coal mine roof layer, and is conducive to the safe production of
the coal mine.

Key words: coal mine; bolt support; roadway support; extremely soft rock roadway; roof layer
