Title: Analysis and Design Considerations for Superimposed Longwall Gate Roads Author: pau0 Created Date: 1/29/ PM. Analysis and design considerations for superimposed longwall gate roads / By G. J. (Gregory J.) Chekan, Jeffrey M. Listak and United States. Bureau of Mines. Abstract. Includes bibliographical references (page 14).Mode of access: Internet Topics.   Summary. Results of instrumentation, test mining and computer aided stability analyses were combined to design the most stable gate road layout for two-seam longwall mining at the Plateau Mining Company. Five layouts were evaluated; these layouts used a combination of yield and/or large pillars with either three-entry or two-entry development by: 4. Analysis and design considerations for superimposed longwall gate roads Technical Report Chekan, G J ; Listak, J M This paper reports that the U.S. Bureau of Mines is investigating longwall panel layouts to maximize coal recovery and minimize interactive problems in multiple-seam operations.

  Recognizing the important role to be played by longwall mining in achieving the proThe influence of the jected doubling of U.S. coal production, it has been endeavoured to outline the basic considerations for longwall design with a special focus on ground control measures. longwall design has been discussed. been given due consideration. geological features, geotechnical considerations, seam characteristics and support system on the The importance of design and stability of gate .

Longwall Gate Roads For LONGWALL USA Pittsburgh, PA May 9, 6/20/ 2 New Ground Support Products For Longwall Gate Roads By: Dakota Faulkner. New Products Outline •New serration design improves anchorage capacity. •Improved resin channels to reduce installation pressure. 6/20/ Analysis and design considerations for superimposed longwall gate roads the transfer of stress from overlying gate roads is a major design constraint affecting pillar stability in the lower.

The Bureau's MULSIM/NL model, a boundary element computer program, was used to analyze load transfer mechanics for superpositioned gate road pillars. Analysis of longwall pillar stability (ALPS), an empirically based design method for longwall gate road pillars, was used to . Analysis and design considerations for superimposed longwall gate roads / by Gregory J. Chekan and Jeffrey M. Listak. the considerations are based on gate roads for the longwall panel before This study concentrates on long-term incremental and sensitivity analysis to determine whether it is feasible to. In the overall design of an automated longwall system, the pressure distribution along the face and gate roads needs to be examined for the following reasons: (1) pillars must be sized to support anticipated loads, (2) roof falls are inevitable under some extremely poor roof conditions and the automated system must be protected from such events when they occur, and (3) system flexibility is required to respond to changing conditions.
