Electrical, mechanical, and hydraulic system improvement study for roof bolter operations. Volume I. Technical information and conclusions. Final technical report as of November 30, 1980
Roof bolters as a generic machine type used in continuous coal miner sections were investigated to determine the effect of machine failures and downtime on productivity, pinpoint the causes of machine failures and downtime, and develop the possible design and operational changes required to reduce machine failures and downtime and increase section productivity. In the course of this program it was determined that the roof bolter is not the major contributor to section downtime. This fact develops from the section work cycle in which the roof bolter can normally complete the required roof control work well ahead of the continuous miner. In addition, the roof bolter is a less costly and more maneuverable machine than the continuous miner which allows a mine to provide a standby machine quickly to reduce the section downtime caused by an individual machine.
