In view of the north wing - 640 m orbital dark slope shaft over the F18 fault broken zone of the roadway support problem, ordinary anchor net cable support can not solve the roadway pressure problem after the deformation, through the support mechanism analysis, anchor joint support mode was proposed, first used "anchor net + anchor cable + primary spray" pressure support, and then "shelter + re-spray + grouting" was adopted to strengthen the support. Practice showed that the support scheme ensured the support strength and the normal use of the roadway, avoided the roadway flushing and expansion repair.
