Abstract
A mechanical continuous mining device integrating microwaves and cutter heads, and a use method are provided. The mechanical continuous mining device comprises an equipment platform, a cutter head cutting system, a microwave fracturing system, a loading device and a cantilever crane. The microwave fracturing system and the cutter head cutting system are fixed to the equipment platform, and the loading device and the cantilever crane are mounted at a front end of the equipment platform. A microwave mechanical longwall mining method for a metallic ore is provided. Microwaves move in sync with machines to break a rock, microwave fracturing methods comprise high-power microwave integral fracturing and local rapid fracturing of soft microwave coaxial lines in the cutter heads; and a lateral cutting method of an ore body by a cutter head technology is applied, a mechanical rock breaking principle is changed from previous extrusion breaking to tension breaking.
