Key technologies and prospects of intelligent tunneling

Aiming at the problems of low efficiency and unbalance of mining in coal mine, the key technologies and development trends in the field of intelligent tunneling are deeply analyzed by constructing the technical framework of “perception-communication-control”. In terms of intelligent perception, the technical status of the condition monitoring of the boring equipment and the perception of roadway environmental parameters is revealed, and the combined positioning system of the inertial navigation unit “IMU+ automatic total station + millimeter wave radar” is developed to effectively improve the downhole positioning accuracy. In the field of communication technology, the “5G+F5G” collaborative architecture is adopted to provide reliable communication guarantee for the centralized control of the working surface and the automatic driving of auxiliary transportation equipment. In the aspect of intelligent control, the multi-level cooperative control system with “centralized control center” as the core is built to improve the cooperative control ability among multiple underground equipment. In addition, based on 5G communication and driverless technology, the shuttle vehicle driverless system under the double-lane driving scene is constructed, and the significant effect of a single shift reduction of 40% is achieved. In order to improve the intelligent level of mining equipment under complex geological conditions, it is still necessary to further strengthen the collaborative innovation of sensing, communication and control technology in the future, so as to provide technical support for safe and efficient mining of coal mines.
