This paper describes a study of three materials-handling tasks performed by low-seam coal miners while kneeling. One of the tasks simulated was the moving of 50-lb rock dust bags. High-speed cinematographic filming techniques were utilized to obtain front and side views of eight experienced miners performing this task. Standard film analysis techniques were used to obtain kinematic records of leg, trunk, and arm action. The results indicate that trunk extension and rotation are the primary actions used to move these bags while in a kneeling posture.
