Equipment Stability Control Technology of Fully Mechanized Coal Mining Face in Steep Inclined Seam

In order to solve the poor stability of the equipment applied to the fully mechanized coal mining face in the steep inclined seam, the low uilization rate of the coal shearer and the low safety protection of the operation personnel, the site actual application and theoretical combined analysis method was applied to study the stability control measures of the face equipment.The results showed that based on the stability of the front powered supports at the tail end of the coal mining face, the anti sliding and anti tumble as well as the powered support adjustment jack shall be installed at each eight sets of the powered supports in order to ensure the stability of the integrated powered support.After the face conveyor head connected with the anti sliding jack, anchor chain and ground anchor, a group of the conveyor anti slidin g chain shall be installed at each seven powered supports to ensure the stability of the conveyor.The unidirectional coal cutting speed of the coal shearer shall not be 0 ver 2 m/min.The flying coal reject prevention device installed in the personnel walking way of the powered supports could ensure the safety of the miners.The advance support quality could be improved with the rebuilt advance powered support group.
