Abstract
The objective of this investigtion was to determine the feasibility of remote installation of roof support and the capabilities and limitations of the operator to perform simple functions needed in providing reliable, economical, remote-control roof bolting. The bolter was to be capable of placing longer-than-seam-height bolts up to 10 ft long, from a seam height of 36 to 72 in, while keeping the operator under canopy and supported roof. The machine, called the rem bolter, is a low-profile unit that utilizes a flexible shaft roof drill, a roof bolt inserter, and a newly designed roof bolt lifter-torquer. Efforts were made to strike a successful compromise between automation and manual control. In a controlled laboratory environment, the rem bolter remotely installed 1,000 bolts. The machine was tested in an operating coal mine where 500 holes were drilled and bolts were installed over a 4-month period. All tests show that the operator of a machine of this kind can quickly and repeatedly install roof bolts remotely from the operator compartment about 8 ft away from the drilling-bolting action.
