Coal Min & Proc 1983 Mar; :61-67
This is the first of a series of three articles. The purpose of the series is to describe the results of approximately 3 years of research, sponsored by the Bureau of Mines, to document the application of cabs and canopies in low coal mines. This article describes a procedure to define the minimum and practical working heights at which canopies can be used without roofing and without restricting operator comfort or vision.
