An automatic microprocessor-controlled roof bolter being developed may dramatically improve operator safety in high coal seams. The operator sits in protected cab where the controls roof bolter module out front. Hydraulic jacks anchor roof bolter module to coal mine floor and roof. Another bolter is described for metal and nonmetal mines which uses a percussive hammer for drilling. The unit operates electrohydraulically during bolting, electric power being obtained via a trailing cable. A diesel engine trams it in the mine.
