Research on the history, evolution and development prospect of China's coal mining technology

China has been exploiting coal resources for thousands of years and nowadays is the most advanced level of coal mining technology in China. Since the founding of Modern China, coal has been the main energy source in China, supporting the country to carry out industrialization, informatization and development of all aspects of society. This paper studies and introduces the basic situation of non-renewable energy sources in China since the founding of the People's Republic of China, the main development process of underground coal mining technology in China, the series of disasters encountered during underground coal mining and the corresponding safety measures, and introduces each coal mining process in detail in chronological order, namely the blasting coal mining process, the conventional mechanized coal mining process, and the comprehensive mechanized coal mining process. The advantages and disadvantages of each coal mining process are also analyzed. Besides, it also analyses the intelligent coal mine that is the focus of attention at this stage, and points out that based on comprehensive mechanized coal mining technology, the intelligent coal mine cannot be achieved without the support of Internet of Things technology, 5G communication technology, big data technology, cloud computing and other technologies, and also analyses the problems encountered in the development of intelligent coal mines, and briefly analyses the future goal of intelligent coal mine development, which is to achieve unmanned.
