Abstract Based on coal roadway support of 2-104 high seam working face in Tenghui Coal Mine, optimization design of intrinsic supporting scheme was carrried out. Meanwhile, reliability of optimization scheme was analyzed to reflect monitoring of actual stress and displacement. The practice showed that new supporting scheme satisfied supporting demand much better than the original one, so that its safety was improved and supporting cost was decreased, which provided technical experience reference to coal mine driving support under other similar geological conditions.
