Thick Board Theory on the Bolting Support of the Ribs in Coal Mine Roadway

Abstract:

According to the character that broken rock mass still has higher compressive strength with appropriate support action though it can not bear tensile stress and deformation character of board with different width-thickness ratios, an idea of keeping the stability of both sides of roadway with anchorage body was put forward, namely, the width(height)-thickness ratio of the anchorage body should be higher than that of the sheet. Thus the higher compression and shear strength can play the main role in keeping the roadway stable. A clear and definite theory for bolting support has been put forward, and the determination methods of geometrical and mechanical parameters of bolting support such as bolting strength, bolt length, spacing, interval of row and bolted length etc. have been deduced.
