At present, coal still occupies a very important position in China's energy use. In the process of coal mining, the impact of safety accidents is immeasurable, so it has attracted the attention of government regulators and coal mining enterprises. In the daily mining process of coal mine, roof accidents, gas accidents and electromechanical safety hazards all pose a major threat to the lives of coal mine workers. Therefore, ensuring coal mine safety must be taken into account. In recent years, in order to implement the decision-making and deployment of the CPC Central Committee and the State Council on artificial intelligence, promote the integrated development of intelligent technology and coal industry, improve the intelligent level of coal mine, and promote the high-quality development of China's coal industry. The state has issued a series of documents such as the guiding opinions on accelerating the intelligent development of coal mines to guide coal mining enterprises to improve their intelligent development level and promote the high-quality development of China's coal industry.
China's coal mine safety prevention technology is in a gradual improvement. The emerging 5G technology is the product of the new era, which makes a qualitative leap in coal safety technology. In coal safety, the correct use of 5G communication technology has important research significance for the improvement of coal safety technology. This paper compares the advantages and disadvantages of different frequency bands of 5G spectrum through experiments, and comes to the conclusion that 2.6GHz + 700m is an integrated communication network deployment scheme suitable for Dahaize coal mine.
