Description
technical field [0001] The invention belongs to the technical field of underground development equipment in coal mines, and is particularly suitable for a high-efficiency and rapid rock roadheading machine for mechanized development of underground rock roads in large, medium and small coal mines. Background technique [0002] In the field of coal mine development equipment technology, the main method of traditional rock tunneling in various mines is blasting, and the blasting technology of underground rock tunnels in coal mines is pneumatic drilling, charging, and blasting; Transported out of the working face; after the gangue on the working face is cleaned up, support with bolts and cables. This blasting rock roadway excavation construction technology has low excavation efficiency, poor roadway formation, high labor intensity of workers, and many potential safety hazards. In the patent No. ZL2015 2 0020520.9, the invention name is a patent for an underground crushing impac...
