NTIS: PB/85-185775 :22 pages
The objective of this study was to propose standardized arrangements for controls in roof bolters. Roof bolting is the most dangerous work in underground coal mines. It is expected that standardized control arrangements would increase safety, minimize training requirements, and promote productivity. This report provides a human factors analysis of roof bolter controls. Standards for control design are suggested. These include the adoption of design criteria such as functional grouping of controls; sequencing controls according to order of operation; standardizing control motion directions; and standardizing actuation force requirements, control sizes, and interspacing. The proposed control arrangements were reviewed by roof bolter manufacturers and MSHA roof control experts; the responses were favorable. Detailed designs for the proposed standardized controls were developed.
