The objectives of the program are to compile and transfer to the coal industry comprehensive operational data on US longwall installations, and to provide abstracts of domestic and foreign literature related to longwall production, productivity, and dust control published since 1975. During the period of August through November 1982, five updated longwall questionnaires were received from operators and two additional longwalls were added to the questionnaire file. Three requests for information from the Data Bank were received and processed. Data from questionnaires were tabulated and analyzed. Also, relevant coal-mining publications were reviewed for articles on longwall mining. Fifteen abstracts were prepared from selected R and D reports, conference papers, and articles in professional journals. These abstracts are included in Appendix B.
