Abstract
In order to improve the withdrawal speed of thin coal seam face,the mining of thin coal seam face can be realized more safely and efficiently.Taking the Ji17-23010 open-cut hole in Pingdingshan No.2 Coal Mine as the object,the roof failure mechanism before and after the opening-cut mining is studied,and the supporting effect of the open-cut roadway under the combined support of anchor,mesh and cable is explored.The study shows that the instability of open-hole roof rock mass results from the influence of mining disturbance,and instability failure occurs under the dual influence of axial force and rock mass weight,compared with traditional shed support,combined support of anchor,mesh and cable can greatly improve the safety of open-cut hole in thin coal seam and improve mining efficiency,thus it is suggested to popularize this kind of support in thin coal seam cutting eyes.关键词
