In increasing occurrence for the cases of energetic collapse around worldwide, manifested by the lack of finite primary energetic resources (oil, gas, coal and uranium) or electricity to the final consumers, and even the desiring for the world’s major energy powers in owning and controlling, the entire chain of global energy in order to use primary energetic resources or electricity as a possible energetic tool or pressure tool in the context of blackmail and profitability, makes this thesis of a great importance and relevance. By the lack of supplying the primary energy or electricity to final consumers leads to the crises that cause societal disproportions causing extreme damage to the safety of citizens, industry, the national economy and thus national security, because all areas of a state economy depend on primary energetic resources or electricity. In this context, the energy security of a state becomes an important pillar of national, regional and international security, bringing safety, stability and well-being to the final consumers for electricity usage.

“…This means that coal mines will be Sustainability 2022, 14, 16400 2 of 17 exposed to greater safety risks and miners' productivity and safety vigilance will fall, thus posing a great challenge to national energy security and coal mine safety [10]. Currently, the main coal-producing countries in the world are using a new generation of intelligent technology to improve the safety level of coal mines [11][12][13][14][15]. China has an urgent need to strengthen the management and technology to guarantee secure, efficient, eco-friendly coal mining.…”

China suffers the worst coal mine disasters in the world. Lots of miners lose their lives or suffer occupational injury. Fortunately, China is developing vigorously intelligent coal mining, which is the combination of traditional coal mining and the latest technology. Mining expects to relieve or solve coal mine safety, health and intensive labor issues and ensure energy security by applying intelligent coal mining. This paper fully reviews the promotion of intelligent coal mining to coal mine safety. Firstly, a brief history of intelligent coal mining is introduced. Then the safety motivation of the intelligent coal mine is discussed in four perspectives, including current the coal mine safety tendency, the positive impact of mechanized coal mining on safety, coal mine safety conception of “Mechanization Replacement and Automation Reduction”, and government initiatives. The intelligent prevention and control scheme of major disasters matching intelligent coal mining are also reviewed in the present paper, including intelligent gas extraction, intelligent coal and gas outburst/rock-burst prevention, and the real-time monitoring of water diversion fissure zone. Finally, the positive impacts of intelligent coal mining on safety are evaluated. Compared with traditional longwall face, the number of miners of coal cutting shift is reduced from 20~30 to 5~7, and the working environment is greatly improved. The statistics have shown that the employees in large coal mines, the mortality rates per 106 tons of coal output, and the number of deaths decreased by 33%, 72.2%, and 66.9% during the period of rapid development of intelligent mining technology (2016–2021). In the future, more and more key technologies and management skills should be introduced, aiming at workless mining and the intrinsic safety of the coal mine. This paper provides a way for safety researchers around the world to understand the tendency of coal mine safety in China.

Purpose. To apply artificial intelligence (AI) technology for predicting the earthing resistor of underground mines with consideration of climate change parameters. Methodology. In underground coal mines of Vietnam, the earthing system are everywhere equipped with individual rods combined with centralized grounding bed; this system significantly influences electrical safety and explosion safety. In daily operation, the resistor of the earthing system must be measured and tested regularly to ensure their value lower than the allowance limit (2). However, because of being affected by climate parameters (humidity and temperature in mines) this value varies frequently. By applying a new Neural Network with 3 hidden layers including variable parameters, the paper presents a new approach on predicting the earthing resistor. An algorithm is formed with visible and easily usable software for assisting the operator to predict the resistor. The prediction could be used for onsite management of a mine operator in the field of observing and testifying the earthing system in underground mines. Findings. Software is developed based on AI technology for assisting the operator to predict the value of the earthing resistor corresponding to climate change. Originality. Neural network with AI technology application is utilized relying on onsite measurements. Practical value. Prediction results could be used in case of difficulty in measurement. It will also help to correct or eliminate the measurement error from a mining technician.
