This report describes the development of skip and guide designs for vertical shafts in deep vein mines. Skip and guide systems for bottom dump skips are identified as being used in current practice. Mine visits were made to obtain current information on the needs and problems of operating mines. Methods of structural and mechanical analysis of skip bodies and bails are outlined. A computer model was written to find the dynamic interaction between skips and guides for guides with geometric misalinements. A materials evaluation section identifies current available and applicable materials that can be used effectively for new skip construction. Design requirements related to the shaft environment are presented. Conceptual design includes the concept of cylindrical skips, center- seeking guide rollers, and asymmetric bail design to decrease dynamic interaction. An outline for field tests is presented.
