Abstract:The technique of sparklet-inboard-type layout is put forward which can be used to lay out the gateroad in the bottom slicing to hypo-high stress area relatively near the coal pillar. The problem of depressing mining benefit due to the bigger inboard distance can be improved by using the roof beam and side bolts. Reinforced concrete and concrete-filled steel tube beams are used in the technique of sparklet-inboard-type layout to increase the available height of gateroad. As a result,the problem of the deficient height of the gateroad in the bottom slicing is resolved.
