Abstract
This is the first semiannual report on Contract No. DE-AC01-81FE00080 entitled Longwall Data Bank. The objectives of the program are to compile and transfer to the coal industry comprehensive longwall operational data representing 95 percent of the US longwall installations and to provide abstracts of domestic and foreign literature published since 1975 related to longwall production, productivity, and dust control. The number of longwall faces operating in the US is steadily increasing, but their full production potential has not been achieved due to problems such as respirable-dust control, excessive move time, roof control, etc. Generally, longwall operators are not knowledgeable of operational data for longwall operations other than their own, nor of results from current longwall research. Therefore, the purpose of this program is to establish more effective technology-transfer procedures. The literature search was completed, except for an ongoing review of weekly abstract publications. Working cards were completed for the comprehensive index file for all longwall publications of interest; abstracts were prepared for selected longwall publications. Revised questionnaire forms, with information from the original questionnaires, were forwarded for updating to nearly all companies presently in the questionnaire file. Selected operational data were tabulated and compared.
