Outline
With the increase in the mining depth of mines with high in-situ stress, the problem of low intelligence level of traditional drilling rigs has become a challenge for borehole pressure relief. To this end, an innovative design scheme for an intelligent mine pressure relief drilling rig was proposed. This intelligent drilling rig integrates four key components, including the chassis walking unit, the drilling execution unit, the support lifting unit, and the drill rod magazine unit. Among them, the unique automatic drill rod changing device realizes the flexible displacement of the drill pipe in the precision track system through the cooperation of the horizontal and the vertical pushing mechanism. With the cooperation of the fixing groove and the clamping mechanism, the automatic drill rod changing operation process can be completed efficiently and accurately, significantly improving the automation level and continuity of the operation. At the same time, the advanced in-drill information monitoring and analysis system built into the drilling rig can capture and analyze multi-source data during the drilling process in real time, laying a solid foundation for precisely adjusting the drilling parameters and promptly warning of potential risks. The overall structure of the intelligent drilling rig, as well as the structure of each unit were introduced, subsequently, based on the analysis of a large amount of drilling information, the excellent performance of the intelligent pressure relief drilling rig was comprehensively verified. Compared to the traditional drilling rigs, the operational safety of intelligent drilling rigs has been improved, equipment failure rates have been reduced, the drilling time and auxiliary operation time have been shortened, and its drilling efficiency has been improved.
