Abstract：The 2225 work face in Xingdong coal mine was a isolated island coal work face of deep mine, the huge pressure caused serious deformation of roadway surrounding rock in the mining processon of passing 2225 detecting roadway , especially the deformation of roadway floor was serious,the roof convergence was controled to a certain extent by these measures of taking the row of crib and installing monomer for safety of passing detecting roadway ,and that the reinforced structure of bolting and grouting was formed through fitting into chemical grouting in the coal body maked strength and bearing capacity of the coal body Significantly en-hanced. The reinforced structure of bolting and grouting had good integrity and stability so as to realize min-ing safety.
