Abstract This U.S. Bureau of Mines report presents an overview of ground control considerations associated with cutter roof failure. Many of the relevant U.S. and international research studies since the late 1940s are reviewed, and summaries of recent design guides are included. Factors affecting cutter roof, such as underground stress field and rock structure around the entry, are described. Strata control techniques are also outlined. These techniques are divided into three sections: artificial support, mine structure design, and multiple-seam extraction. Other subjects covered in the report include monitoring and prediction, effect of geologic features, and mapping of adverse mining conditions. The emphasis of this report is on practical considerations; theoretical discussions are minimal.
