More Information
Summary:The utility model discloses continuous mining equipment for crushing hard rocks. The continuous mining equipment comprises a cutting mechanism and a crushing mechanism, the crushing mechanism comprises a drilling tool system, a supercritical carbon dioxide system and a microwave system. Firstly, rock drilling and vibration fracturing are conducted on an ore body through the drilling tool system, then supercritical carbon dioxide is sprayed into rock drilling holes and cracks of the ore body through the supercritical carbon dioxide system, and then the sprayed supercritical carbon dioxide is heated through microwaves emitted by the microwave system to enable the supercritical carbon dioxide to be rapidly heated and rapidly subjected to phase change so that the ore body can be pre-crushed; and finally, the pre-crushed ore body is cut by the cutting mechanism until mining is completed. According to the mining equipment, for a hard rock or super-hard rock ore body with the rock firmness system coefficient f large
