Research on the Status Quo and Existing Problems of Digital Mine Development in China

The process of digital mine construction is a perfect process to improve production management, transform business mechanism, promote management modernization, establish a modern enterprise system, improve economic efficiency, and promote safe production. It is also a strategy for the coal industry to achieve cross-regional, cross-industry and implementation of large groups. Take the technical guarantee of sustainable development. The digital construction of the coal industry can improve the predictive and predictive precautions and preventive precautions of coal mine safety management, and promote the transition of safety from static management to dynamic management, from passive management to active management, from procedure management to process management. The inevitable choice and important way of production.
Second, the status quo of China's coal industry digitalization China's coal industry digitalization process started earlier, but in the 1990s, the overall economic efficiency of the coal industry declined, and the digitalization process was greatly frustrated. With the recovery of the coal industry, the digital awareness of coal enterprises has been greatly improved, digital management systems and information security systems have gradually formed, digital technology innovations have progressed rapidly, and the pace of digital infrastructure construction has accelerated.

First, digital construction to promote safe production and improve management efficiency is becoming an important part of the development strategy of coal enterprises. Most enterprises regard the digital construction of coal mines as an important part of the overall development strategy of the company. Most large coal enterprises have set up a digital mine leading group, set up a full-time management department, and established a relatively sound organizational management system; the pace of digital infrastructure construction has accelerated. According to incomplete statistics, coal enterprises have applied more than 200 kinds of software in production, safety, management, sales and logistics. Most large-scale enterprises have established an integrated information automation control platform integrating automation control, dispatching command, monitoring, monitoring and diagnosis and maintenance, and gradually realized the digital platform for the whole process of coal production, energy saving and emission reduction, washing and processing, and modern logistics.
Second, the digital mining system is developing from decentralized isolation to integration. At present, digital construction promotes safe production work from a decentralized, single safety information system construction to a comprehensive, integrated and integrated safety management platform. Most enterprises focus on single-system applications such as hazard source monitoring, communication, production process and equipment monitoring, and personnel positioning to meet professional management needs. Some advanced enterprises are also developing from single application to integration, from all aspects of security, health, environment, etc., and gradually achieve overall control.

For example, around the goal of building an intrinsically safe enterprise and digital Shenning, Shenhua Ningxia Coal Industry Group Co., Ltd., Beijing Tianda Tianke Technology Development Co., Ltd. and Tiandi (Changzhou) Automation Co., Ltd. jointly launched the “Digital Mine Construction Integration Technology Research” project. . The project makes full use of modern information technology to realize the automation of the whole mine production process, realizes the seamless integration of mine comprehensive automation, enterprise management, 3D geographic information system and decision analysis system, and realizes the visualization of mine site operation environment and production process. The online analysis of real-time data for safe production has been realized, and the decision support ability of mine safety production has been improved. The project has been successfully applied in mines such as Shicao Village Mine and Hongliu Mine, and has achieved good economic and social benefits and reached the international advanced level.
Third, the key link of safe production has become an important entry point and breakthrough point for digital mine construction.

For example, the “Eleventh Five-Year” National Science and Technology Support Program, which was organized by the Science and Technology Department of Shanxi Province and completed by the Taiyuan University of Technology, “Digital Monitoring and Monitoring of Coal Mine Safety Production and Monitoring of Major Disaster Early Warning System” passed the acceptance of the Ministry of Science and Technology. The integrated system of fire, flood and major gas disaster prediction and early warning monitoring, as well as mine ventilation, roof and power supply system safety status continuous monitoring and disaster warning, enables the mine monitoring system to achieve digital and remote monitoring and control, and to ensure the safe production of coal mines. Continuous, reliable and stable implementation, improving the early warning capability of major disasters in coal mine safety production, and promoting technological progress and industrial development in the coal industry have significant economic and social benefits and important strategic significance. In the three years since the Shenhua Group’s “Intrinsic Safety Management Information System” was in operation, the unsafe behavior of personnel decreased by 33%, and the death rate per million tons was reduced by 20%.

Fourth, the digitalization of safe production has become an important carrier for coal enterprises to implement safety management systems. Through the digital means, coal enterprises have ensured the implementation of various safety production systems, especially in the aspects of standardization of safety production processes, implementation of safety production responsibility and assessment. Some enterprises also use virtual reality and digital simulation to simulate the safe operation process and emergency handling, provide new means for safety production training, and improve the staff's understanding and practical ability of safety management system. Xingtai Mine of Jizhong Energy Co., Ltd. is equipped with KJ75N coal mine safety production monitoring and control system in the prevention and control of gas. It adopts two methods of “gas monitoring and manual inspection” to effectively prevent the gas from exceeding the limit to the safe production of mines. Hazard provides a reliable basis for analyzing the gas situation at the site.

Fifth, the professional digital service industry is gradually growing. With the continuous development of digital construction of coal mine safety production, the ranks of information technology service providers are also expanding.
Third, the problems of the digitalization of China's coal industry First, some leaders pay insufficient attention to digital construction, do not regard digital construction as an opportunity and opportunity for the development of enterprises themselves, but think that digital construction has large investment, low efficiency, and even lose money.

Second, the application level of digital promotion of coal mine safety production is not high, and the integration of digital and safety production business is not enough. Digital mine is a complex system involving coal mine planning and design, safety production, operation management, and enterprise decision-making. Many information needs long-term planning and continuous sharing. In practice, some coal mine enterprises lack specific planning for digital construction. Randomness and blindness. In particular, some mines are expanded, and they are limited by funds, production, technology, and concepts. They often implement a certain set or sets of subsystems on a case-by-case basis, forming an “information island”.
Third, the standardization of the application of safety production information technology is low, and the standard specifications of software platforms, hardware devices, information content, and communication protocols are not uniform.
Fourth, the scale of independent digital service enterprises is small, the degree of specialization is relatively low, the competitiveness is relatively weak, and some core technologies are subject to people. There is a risk of serious safety risks due to the quality of products and services.

Fifth, there is a lack of corresponding policy guidance and special fund support, and some of the policies that have been formulated are not in place. The digital construction and development of coal mines is not a one-off event. China's coal mine digital mine is still in the primary development stage, and needs to fully consider social, management and economic benefits, adhere to the principles of safety, practicability, reliability, advancement, adaptability and openness, and steadily and steadily carry out digital mines. Building a development path.
