Development trend and path analysis of China's smart mine

1.3 Problems in the construction of intelligent mines

First, the concept of smart mine is unclear. At present, the understanding of intelligent mine is still relatively one-sided, that intelligent mine is the realization of digitization, automation, unmanned operation in all aspects of mine production, so as to improve management efficiency and realize resource intensification. However, the more significance of intelligent mines is reflected in the realization of digitalization, automation and collaborative control of various elements, and its operation system must also have the ability of perception, analysis, reasoning, judgment and decision-making.

Second, the concept of intelligent mine construction is outdated. There are many kinds of mineral resources in our country, the total amount is large, but the big ore is less, and the medium is inchworm. Less open-pit mining, more mine mining; Less independent ore, more common (associated) ore. Regional differences are great, so the construction of intelligent mines should be adapted to local conditions, and appropriate ways and methods should be adopted to realize the intelligent construction of mines. However, many mines copy in the intelligent transformation and construction, and can not formulate intelligent mine construction plans according to the actual situation.

Third, the intelligent mine construction system is not mature. The links of intelligent mine construction lack linkage, information and data are isolated, and a system cannot be formed, which makes the benefits of intelligent construction of a single link greatly reduced. Intelligent mine is a comprehensive system that combines digitalization, automation, intelligence and other technologies closely with the mine production and management process to realize intelligent mine production and management. For most mines in our country, system construction has become the biggest difficulty and pain point.

Fourth, the smart mine policy support is insufficient. The state proposed to "promote the green transformation of the mining industry enabled by digital technology" as an important task for the transformation and upgrading of mining enterprises and to accelerate the development. However, on the whole, the support policies and support are still slightly insufficient, for most small and medium-sized mining enterprises, the systematic intelligent construction benefits are not enough to cover the construction costs. At the same time, mining enterprises are difficult to predict the survival and development, which also affects the decision-making and promotion of enterprise upgrading.

Fifth, the supporting industries of intelligent mines are not perfect. At present, most third-party technology enterprises rely on information services, in addition to 5G mining technology, the lack of sufficient strength of science and technology enterprises to support the intelligent construction of domestic mines, intelligent mining equipment manufacturing and production services and other industries are not perfect and do not support the system.

Overall, China's mining intelligent technology research and development started late, compared with the international advanced level, most mining enterprises have a low degree of production automation, decentralized system, poor information integration, especially the level of three-dimensional geological modeling of resource reserves management is not high. With the rapid development of China's digital communication technology, it has greatly promoted the rapid development of China's intelligent mine construction, and some links have even been in the international leader, but there is still a certain gap in the systematic and comprehensive aspects.

2，Intelligent mine development trend

In order to lead and standardize the mining industry to accelerate the construction of intelligent mines, the Ministry of Natural Resources organized many automation design units, scientific research institutes, universities, mining enterprises, etc., after more than two years of efforts, compiled and released the "Intelligent Mine Construction Code" (DZ/T) 0376-2021) Industry standard, become an important guide to promote the automatic intelligent application of the whole link of mine exploration and development. At the same time, the practice of industry standard implementation has been increased, and 16 enterprises have been included in the Ministry of Natural Resources "smart mine construction standard pilot unit", through the practice demonstration of these mining enterprises, it will inevitably become a model of smart mine construction with Chinese characteristics. In addition, in the Catalogue of Advanced and Applicable Technologies for the Conservation and Comprehensive Utilization of Mineral Resources (2022 edition) issued by the Ministry of Natural Resources, digital information technology is regarded as an important field, and many digital intelligent technology and equipment applied by scientific research institutions and mining enterprises are included in this catalogue. Overall, the development trend of smart mines is reflected in the following aspects.
