Abstract： The accuracy and stability of underground communication in coal mine is crucial in emergency rescue. At present， the positioning accuracy of underground communication system in coal mine is poor. Therefore， a coal mine emergency rescue communication system based on an improved online sequential extreme learning machine （OSELM） algorithm is proposed， and corresponding simulation experiments are conducted. The results show that the median packet loss rate of the coal mine emergency rescue communication system constructed on the basis of the improved OSELM algorithm in Experiment 1 and Experiment 2 is 1.7×10-4 and 1.4×10-4， respectively. Its median packet loss rate is significantly lower than those of the communication systems based on the other comparative algorithms. The positioning accuracy of the improved OSELM algorithm， EfficientNet algorithm， OSELM algorithm and ELM algorithm are 96.8%， 83.8%， 76.4% and 71.0%， respectively， in Experiment 1 and 95.9%， 82.5%， 75.8% and 70.4%， respectively， in Experiment 2. It can be seen that the improved OSELM algorithm is superior in terms of positioning accuracy， and the communication quality of the coal mine emergency rescue communication system based on this algorithm is also higher. Experimental data prove that the study provides an efficient and stable method for the coal mine emergency rescue communication system， and an effective solution strategy for practical problems.
