As one of the key processes in the stage open stope with subsequent filling mining method, the quality of the slot raise construction directly affects the effect of the subsequent blasting to form the cutting groove, and ultimately affects the quality of large-scale caving mining. In view of the problems of low intelligence, high safety risk and large occupational injury in the construction of traditional artificial sight distance operation raise boring machine, combined with the mining status and occurrence conditions of porphyry ore body in Shanxi Zijin, the existing construction mode of slot raise was optimized to realize the intelligent construction of slot raise. A dynamic optimization control technology for operation parameters was proposed, which used the mountain climbing method to achieve dynamic parameter optimization, and achieved autonomous and efficient continuous drilling through a remote intelligent control system based on 5G communication technology. The industrial application results show that the raise boring machine with remote intelligent control system can also maintain high-precision hole drilling and hole expansion operations in complex rock formations with fractured zones, with an average pilot hole footage of 1.75 m/hand an average reaming footage of 1.375 m/h, and a deviation rate of only 0.68%. The study can provide a reference for unmanned construction of wellbores in other scenarios.
