In order to ensure application efficiency of roadway driving along coal seam during fault period and simplify production systems and transportation links so that simultaneous drifting could guarantee, drilling and expected profile were combined effectively to reduce or avoid fluctuation times of roadway, blindness of construction and waste caused by repeated drilling. At the same time, roadway standard was optimized as well which provided reference for planned uncovering coal, so that achieved purposes of timely prediction, advance prevention, safe production.
