Get PriceJun 01, 2017 From the point of view of operation, the bolt length should be less than half of the opening height for roof bolts and half of the span for wall bolts in order to avoid installation difficulties: (1a) L b ≤ 0.5 H (for roof bolts) (1b) L b ≤ 0.5 B (for wall bolts) where L b represents the bolt length, H is the opening height, and B is the opening span. The bolt length is also associated with the bolting principle
