Abstract
This paper outlines an analytical approach to determining the "minimum working heights" and "lowest practical working heights" necessary to allow the safe use of canopies on underground coal mining equipment. Each element of the working height (mine floor to nearest overhead obstruction) is discussed in some detail, emphasizing the variability of the numerical values assigned to each element. The effects of machine type, machine frame height, and mine conditions on the working heights attainable with canopies are reviewed. With state-of-the-art cab and canopy technology, these variables will frequently prevent the safe use of canopies in low coal seams without extensive modifications to existing equipment.
