This document discusses several mining equipment technologies: a double ended ranging drum shearer with drums at the front and rear of the body; a roadheader excavation machine with a boom-mounted cutting head and conveyor; a mechanized roof bolter used to install bolts in mines; a hydraulic face drilling rig for precise, automated drilling; environmental telemonitoring systems; and in-pit crushing and conveying systems. For each technology, several advantages are listed but not described. The document also includes references but no other content.

7. CONTINUOUS MINER/ROAD HEADERS
A roadheader, also called a boom-type roadheader, road header machine, road
header or just header machine, is a piece of excavating equipment consisting of a
boom-mounted cutting head, a loading device usually involving a conveyor, and a crawler
travelling track to move the entire machine forward into the rock face.
