Final Design Report on a Remote Controlled Hi-roof Bolting Machine for Use in High Roof Areas of Coal Mines.
For Reference Only At Bureau Libraries :114 pages
This report covers work done on the preliminary design of a remote controlled high roof bolting machine. The design program involved the investigation and analysis of roof fall characteristics to determine the feasibility of developing a remote control high roof bolting machine. Several conceptual machine designs were generated and evaluated. Trade studies were made and preliminary evaluation meetings were held to determine the most promising concept to be carried through to the preliminary design stage. Visits were made to several coal mines to observe and to become familiar with typical problems associated with roof fall and overcast areas. Results of the observations and further studies of data indicated that drilling and bolting from vertical to horizontal angles would be required to cover most roof fall areas.
