Study on safe distance between cross-cut and lower belt tunnel
In order to solve the question of safe distance between cross-cut and lower lane bolt tunnel and support,aim at geological and mining conditions of north mining area in sanjiaohe coal mine,and analysis mechanism of surrounding rock deformation,analysis the upper roadway surrounding rock stress,displacement and distruction of plastic by FLAC3D determine the minimum distance between the two tunnel and design support scheme on the basis of on-site roadway conditions.Result of this study can provide a reference not only in this mine but also for another similar situtions roadway.
