Abstract: Medium thick seam occupies a large proportion in seam reserves, and the support suitability has a direct effect on high yield and high efficiency of the working face. This paper analyzes the support suitability for fully mechanized coal face of Shanbula Coal Mine by site measurement, it gets that the initial support force of support takes up 32.6% of the rating setting force, the maximum working resistance takes up 51.9% of the rating working force, the type of ZY6800-11/23 hydraulic support is too large for working face.
