en.Wedoany.com Reported - Recently, the Coal Science and Technology Research Institute Co., Ltd. (China Coal Research Institute, CRI), a subsidiary of China Coal Technology and Engineering Group Corp. (China Coal Group), has completed the first verification of an integrated testing system for the dynamic performance and anti-interference capability of mine inspection robots. This verification simulated the real electromagnetic environment of underground coal mines, simultaneously testing the robot's dynamic performance and anti-interference ability, confirming the reliability of mine inspection robots operating under complex working conditions.
China Coal Research Institute (CRI) is a key secondary backbone enterprise under China Coal Technology and Engineering Group Corp., located in Beijing, China. It is a benchmark "Science and Technology Reform Demonstration" enterprise under the State-owned Assets Supervision and Administration Commission (SASAC) of the State Council and a national high-tech enterprise. Focusing on mine safety and clean low-carbon fields, CRI is primarily engaged in research, development, and commercialization of clean coal utilization, safety technologies and equipment, and testing and inspection.
Inspection robots play a crucial role in replacing manual inspections in underground coal mines. Their dynamic driving stability, control reliability, and electromagnetic interference resistance directly affect operational safety and efficiency in complex underground environments. To conduct this verification, the CRI electromagnetic compatibility innovation team previously conducted a five-day on-site investigation and testing at two mines under the Guoneng Shendong Coal Group Co., Ltd. (Shendong Coal Group) in Ordos, Inner Mongolia Autonomous Region, China. They systematically collected and analyzed electromagnetic interference information from the actual working environment, compiling nearly a hundred pages of records and thousands of data sets, providing foundational support for the testing. Shendong Coal Group is one of China's largest annual coal production bases, with a total output of 190.48 million tons in 2025.
During the verification process, the research team used a self-developed integrated mechanical action and electromagnetic environment testing device to realistically replicate various working scenarios of the robot, including walking, stopping, and climbing slopes. They innovatively applied an integrated testing solution. The inspection robot prototype underwent operational radiated emission testing and radio frequency electromagnetic field radiated immunity testing, with the immunity test level reaching the highest requirement for mining products (Level 3), indicating that the equipment has achieved a high industry standard in radiated immunity. Researchers used video monitoring and remote control to achieve full-process image retention and precise data collection throughout the testing.
The integrated testing system used for this verification enables simultaneous testing of the inspection robot's dynamic performance and anti-interference capability, effectively improving testing efficiency and comprehensiveness. This verification work was carried out under a key fund project of China Coal Technology and Engineering Group Corp. Currently, the "Integrated Testing Device and Method for Dynamic Performance and Electromagnetic Compatibility Anti-Interference of Mine Inspection Robots" has been submitted for relevant patents.
