A walking mine support includes a roadway support unit and a face-gallery support unit laterally of the same. The two units are linked by one or more four-pivot couplings whose members can tilt both lengthwise and transversely of the elongation of the roadway and permit walking movements of the units with reference to one another without interfering with proper support of either the roadway or the face-gallery.

Walking mine support

A walking mine support unit has a pair of adjacent supporting frames each having a multi-partite sole plate and a multi-partite roof shield. The sole plate and roof shield of each frame are connected only at their respective leading and trailing ends, by hydraulic rams which permit the roof shields to be raised and lowered relative to the sole plates, and by four-bar linkages which permit length-wise displacement of the roof shields parallel and relative to the sole plates. A multi-section overshield is located above each of the roof shields and connected thereto by adjustable supports. An arrangement is provided for advancing the unit in stepwise manner.
