Abstract
The design synthesis and the establishment of design criteria presented in this report is based on a critical review of the first four volumes of the report. The design synthesis points out some practical aspects of roof control using bolting but definitive design criteria were not obtained. The current code of federal regulations title 30, part 75, is examined and recommended modifications are given.
