The Qi Dong county coal mine had been exploited for coal seam group in which the combination layout of district roadways had been adopted.So existence had always been lifted up and the coal seam phenomenon appeared in rock alley construction process.A coal seam by the passive shoring of U29 type shed stiffness to be under construction is not only with lower construction progress 、higher shoring cost but also higher tunnel pressure 、stress concentration and difficult shoring.Sometimes it causes the situation of frequently revision which brings severe threat to safety production.According to this problem

this paper illustrated bolt support technology feasibility study on the coal seam gateway.
