ABSTRACT:
A method of mining a mineral deposit from a remote point, particularly useful in mining pitching or horizontal seams, comprises boring, casing and preparing a log of a probe hole; the casing will later be used as a guide for the mining head. All personnel are remotely located from the mining face and the mining head follows the probe hole and is rotated by means of a novel drive stem powered from a portal based plant. Thrust is imparted to the rotating mining head in a non-cyclical manner by the intermittently supported drive stem. The mineral being mined is automatically removed from the face and discharged at the portal. Steel or reinforced concrete support collars follow the mining head and support the drive stem until the bore is mined out whereupon the collars, the drive stem and the guide are removed for reuse.
