Abstract
In view of the problems of separations of the broken roof of the transportation channel,significant floor heave amount of the roof,and difficulty in support when the 1502 fully mechanized mining face of Yunquan Coal Industry passing through the geological structure zone,the plastic zone range and failure depth of roadway deformation and failure is analyzed by the help of numerical simulation.A surrounding rock control scheme for advanced support+long and short full anchor cables+floor reinforcement support is proposed.The on-site monitoring results indicate that the displacement amount of the top,floor,and two sides of the three measuring points tends to stabilize around 20 d,with the average displacement amount of the top,floor,and two sides stabilizing at 31 mm and 22 mm,respectively.By using electronic peeper,the left and right sides of the roadway are peeked,and the coal seam is a stable coal seam without developed cracks.It indicates that the support effect is good and can ensure the safe passage of the mining working face through the geological structure zone.关键词
