Abstract
This paper describes a study of the feasibility of introducing three longwall mining methods--high-face, multislice, and caving--into western coal operations. Geological factors affecting the development of these methods (thickness and three-dimensional configuration of the seam; cleats, joints, and fractures in the coal and roof rock; and coal quality and changes in quality within the seam) are discussed, and the specific applicability of the three proposed longwall mining methods are outlined.
