[0002] Prospecting machinery is a general term for mechanical equipment used in prospecting engineering construction, mainly including various types of drilling rigs, drilling towers, mud pumps, winches, generators and other equipment. In the rope coring of solid minerals, wire ropes often break and form burrs when fishing out the cores. In serious cases, the wire rope breaks and causes the core inner tube and coring assembly to fall out of the hole. It is necessary to use a large drill to remove the core and drilling tools in the hole, which seriously affects the drilling efficiency.
