Present situation and developing trend of mining technology in China

(2) Deep well mining technology. With the continuous development of mining engineering, the shallow resources in our country have also been sharply reduced, and we have to dig from deep, for the length and depth of deep Wells, there is no very clear concept, but our country will generally exceed 1000m mines, named deep mining. Because the mineral deposits are buried deeper, the ground pressure is greater, and the rock temperature will also increase. Therefore, in the process of mining minerals, it will encounter unimaginable technical problems, such as mine lifting, drainage, support, ventilation and a series of problems that cannot be solved by manpower. In order to reverse this situation, we can only start with mining technology and mechanical equipment, comprehensively improve the adaptability of machinery, improve the performance of mining technology and mining machinery and equipment, so as to effectively ensure the safety of mining engineering and the efficiency of mining mining.

(3) Develop green mines. From the point of view of environmental protection, mining projects will not only destroy the natural environment, but also leave industrial "sequelae" such as waste gas, wastewater, waste residue, which will bring strong damage to the natural environment and natural air. Therefore, the protection of the mine environment has become the primary theme of environmental protection. First of all, it is necessary to study the method of waste utilization, secondly, it is necessary to use environmental protection means to establish pollution-free mines and clean mines, and finally, environmental systems such as pollution-free and destruction-free are incorporated into the system implementation of mining regulations.

(4) Develop digital and intelligent mines. The development of information technology, while bringing benefits to mining technology, also provides professional skills in engineering design, production scheduling, disaster forecasting, system monitoring level, so that mining technology can continue to develop. What the digital mine is aiming at is the whole of a mine, which is also the reproduction and understanding of digitalization. It takes the application technology software of the mine as the tool, takes the highly skilled and automated data acquisition system as the means, and finally aims to realize the unmanned mining and intelligent mining as well as the high-speed information network system of the mine, and collects the actual data for the various projects of the mining site. The monitoring system is implemented to allow various mining processes and mining processes to be carried out at the same time, and to make accurate judgments on various working environments to achieve intelligent real-time management. Although this technology is still far away from us, as long as we have firm confidence, forge ahead, and gather all manpower, weakness, and financial resources, and plan and step by step to realize the mining content of digital mines, this day is no longer far away from us.
