In the process of mining, mining companies need to use 3D technology to create a more realistic simulation of the mines in order to better reproduce the actual mine conditions. In order to make detailed plans for its subsequent mining and other work.
1 Comparison of 3D digital mine software at home and abroad Surpac 3D digital mine software is a widely used 3D digital mine software system in foreign countries. This software is developed by Australian SUR-PAC M NVEXGROU P (SURPAC). To date, it has evolved from an engineering software originally used for measurement to a comprehensive mine environment simulation software. The main uses of the software include: exploration and simulation of geology, drilling and cataloging, mining production schedules, tailings library design, etc.
In addition, the United States, Canada, Australia and other developed countries have developed a number of software systems in the mine three-dimensional digital simulation, such as Micromine GBISGBIS, this software can efficiently and flexibly carry out three-dimensional mine data and environmental simulation, and has an independent generation of mining production schedule; in addition, foreign mining software company has also developed a KANTAN3D and other software that can effectively analyze geological data metal deposits, while the fastest build a three-dimensional surface model of the ore body Models such as 3D models and fault 3D, these systems are capable of autonomous storage management, enabling mining companies to get rid of cumbersome operations and greatly improve work efficiency.
At present, the three-dimensional digital mining software used in China has DIMINE, 3Dmine, etc. Among them, DIMINE is developed by China and is specially used for metal mining software; this software can effectively conduct geological exploration on metal mines. Work and store and measure the data. At the same time, the software can also carry out open pit mining design and production work, and can also design underground mining and production work; and 3DMine 3D mining engineering software as a The company independently develops and designs innovative 3D mining software platform. Its main functions include 3D visualization core, CAD aided design and original data processing, exploration and blasthole database, mine geological modeling, geological reserve estimation, open pit mining design, underground mining design, Mining planning, measuring instrument interfaces and data applications, etc., with more open data compatibility and other functions. Compared with foreign 3D digital mine software, these domestic mine softwares are more complete and professional, and are simpler and more flexible in operation, and also have a cheaper price advantage.
2 Mining software in the mining process of metal ore
2.1 Three-dimensional modeling of mines The three-dimensional modeling technology of mine software is mainly based on the geology of the deposits, and the information is constructed in three-dimensional space. Finally, the three-dimensional model of the geometry is established and then displayed by the graph. The model can be used in a variety of deep levels; once the database of the model is built, it is possible to quickly learn important information such as drilling trajectory lines, rock mass characterization data, tunnel sampling trajectories, faults, etc. In the three-dimensional space, you can understand the actual geological conditions in detail; and in the mine software, you can also view, edit, and manage multiple databases in a timely manner, so as to facilitate batch processing of various data.
2.2 Solid Model The 3D modeling technology of mine software can simulate the model of the entity. The model of the entity can display the cutting surface at any position, and can complete the intersection operation between the object surface and the body.
2.3 Open-pit mining and low-mining design Open-pit mining design tools enable the design of the mining site from the bottom up and from the top to the bottom. During the entire mining design process, the design of the mining can be carried out according to the actual situation. Setting; the setting of the slope can be expressed by angle and percentage, and the 3D model of each stage can freely change its slope and size, and the models can be superimposed. Underground mining design can be presented in a digital image on the screen through 3D design tools in the software, which provides a convenient way to build a patio or roadway for a solid model.
2.4 Development trend of mining software in China
At present, the use of digital mining software by metal mining enterprises in China is still at the initial stage. The development and use of domestic mining software can realize the digitalization and information management of the mining process of mining enterprises in China to a great extent. At the same time, the simple operation mode is also convenient for us to use and learn. At the same time, China's mine 3D digital mine software has the same functions as foreign 3D digital mine software and also has the ability of foreign software, which is not available in foreign mines. The development of software is on the rise.
3 Conclusion
At present, the total amount of mineral resources that can be mined in China is getting less and less. At the same time, the harsh mining environment of metal mines makes the available technical ore in China more and more scarce. Therefore, we continue to be able to carry out high efficiency. The safe mining software, which makes the development of digital 3D mining software occupy the leading position of the mineral enterprise; China's 3D digital mining software has all the basic functions of foreign software, and it is also highly targeted to metal mines. The exploration and design capabilities have a wide range of applications and development prospects in the field of metal mine development in China.
