National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Development of Vertical Shaft Skip and Guide Design.

PB283776

Publication Date	1977
Personal Author	Penning, F. A.; Zabel, D. C.; Seitz, D. H.; Brandenburg, E.
Page Count	254
Abstract	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. Guide materials are also presented. Analysis includes the economies resulting from streamlined buntons and from low-skip payload ratios. Selection of materials is based on strength, abrasion, and corrosion resistance. Design requirements related to the shaft environment are presented. Consideration for the selection of guides and buntons is also given. 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.
