Standardization of Controls for Roof Bolter Machines. Phase I: Human Factors Engineering Analysis

摘要

The objective of this study is to propose standardized arrangements for controls in roof bolters. 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. Preliminary standards for control design 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.
