Description

TECHNICAL FIELD

[0001] The application belongs to the field of uranium mining, and particularly relates to a distributed uranium mining holographic regulation system and method. BACKGROUND

[0002] Uranium is an important nuclear material resource with high economic value and strategic significance. Its mining and utilization have a profound impact on the country's energy security and economic development. Among them, the in-situ leaching mining technology gradually becomes the mainstream method of uranium mining due to its high economic benefits, small environmental impact and high resource utilization rate. However, uranium reservoirs are often buried deep and have complex geological structures, and the permeability characteristics of different reservoirs differ greatly. Traditional exploration and mining techniques cannot accurately detect the permeability characteristics of the reservoir in real time, resulting in low mining efficiency. The regulation of equipment and processes relies on manual operation, making it difficult to respond to changes in the reservoir and complex geological environments in a timely manner. It is not conducive to precise mining and resource protection. At the same time, the lack of real-time data monitoring and feedback mechanisms during the mining process leads to information lag, making it difficult to quickly adjust production strategies, thereby affecting the overall efficiency and safety of mine production. Therefore, it is particularly important to develop a distributed uranium mining holographic regulation system.

[0003] In recent years, some mine management systems based on automatic control and Internet of Things technology have emerged. These systems use sensor networks, data communication technology and big data analysis tools to realize the monitoring and management of some equipment and environment in the mine. However, the application of these technologies in uranium mining is still immature, especially in detecting the permeability characteristics of the reservoir, reasonably allocating work tasks according to the production plan and reservoir conditions, and real-time monitoring and regulation. There are still large technical gaps.

[0004] Therefore, there is an urgent need for a distributed uranium mining holographic regulation system and method that can efficiently coordinate and dynamically adjust the injection wells and pumping wells in uranium mining, realize real-time monitoring of geological conditions, and actively detect and efficiently feedback reservoir data, providing technical support for mine management and production optimization based on big data and artificial intelligence. Through the research and application of this distributed uranium mining holographic regulation system, important technical support will be provided for efficient uranium mining, promoting the sustainable development of uranium resources and assisting the implementation of the country's energy strategy, making important contributions to safe, clean and efficient nuclear energy utilization. SUMMARY

[0005] 1. OBJECT

[0006] The embodiment of the present application aims to provide a distributed uranium mining holographic regulation system, which realizes efficient intelligent mining of uranium mining area based on mining area decision and display unit. The system sends the established production instruction through the mining area decision deployment center, and according to the proven reservoir permeability characteristics, the distributed autonomous regulator efficiently and reasonably allocates the work tasks of each injection well and pumping well. At the same time, the low-frequency high-energy seismic source generator generates a seismic source which is received by the receiving-transmitting signaler through the uranium reservoir, and the receiving-transmitting signaler can actively send a detection signal to the uranium reservoir, and then convert it into the reservoir permeability characteristics, and feed back to the distributed autonomous regulator in real time. In this way, the resource mining cost is effectively reduced, and the mining efficiency and intelligent degree of the uranium reservoir are significantly improved, promoting the intelligent, safe, green and efficient use of uranium resources.
