Abstract: In order to realize the goal of safe and efficient recovery of coal resources,goaf passing technology is adopted in 12113-2 fully mechanized working face of Liuta Mine,after opening the empty roadway,the reinforcement supporting method is used by using roof cable,roadway bolt,wood point,pile and mesh,besides that the detection method of top and bottom coal and roof preinjection polymer materials are applied,the safety of roadway roof is guaranteed and safety production during passing empty roadway is ensured.Based on the above discussion results,the safety guarantee technology when passing the empty roadway is proposed.Huge economic benefit is created by making good preparations before passing the empty roadway and reasonably determining the coal cutting technology during the period of passing the empty roadway,which can provide technical support and experience reference for the safe and fast passage through the empty roadway of the working face with similar conditions.

Key words: Fully mechanized working face, Passing empty roadway technology, Integrated support, Economic benefit
