Description

Coal digital mine geological prospecting data management system

technical field

The embodiment of the present invention relates to the field of computer technology, in particular to a coal digital mine geological survey data management system.

Background technique

"Digital mine" is a unified understanding and digital reproduction of the real mine as a whole and related phenomena. The core of "digital mine" is to scientifically and rationally organize various types of mine information under a unified time coordinate and Comprehensive, efficient and orderly management and integration of mine information resources. The task of "Digital Mine" is to make full use of modern spatial analysis, data mining, knowledge mining, virtual reality, visualization, network, multimedia and scientific computing technologies on the basis of mining information data warehouses to provide resources for mineral resource assessment, mine planning, and development. Simulation, simulation and process analysis provide new technology platforms and powerful tools for design, production safety and decision management.

The main application areas of the existing "digital mine" are concentrated in the fields of oil and gas and metal minerals, and the coal industry is very weak. A large number of foreign scholars have successively carried out a lot of related work on "digital mines". These research results are mainly concentrated in the field of oil and gas and metal mines; the theoretical research of domestic 3D geological modeling is relatively lagging behind, and the research field is also concentrated in oil and gas and metal mines, while the research work in the field of coal mines is almost just getting started. Zhang Chong et al. (2010) carried out research on 3D geological modeling and visualization applications of coal mines. Modeling was divided into blocks by faults, and the boundaries of blocks were corrected using fault models and collaged into a complete coal mine geological body model. Finally, a surface-based model was established. multi-layer 3D geological model. On this basis, a practical application system is established by using OpenGL technology. The modeling accuracy of this system is low, and it has little guiding significance for actual production. Sun Xin (2012) used foreign Minex 6.0 software to take the Heishan Open-pit Coal Mine in Houxia Coalfield, Xinjiang as an example, and successfully imported its drilling data, coal seam information data and coal seam structure data into the Minex 6.0 database, realizing the drilling 3D visualization of borehole data, but only for near-horizontal or gently sloping coal seams. Wang Jinjin et al. (2011) established a 3D geological dynamic model of the Yilan Open-pit Coal Mine based on the 3D geological modeling technology of AutoCAD to achieve dynamic updating, and the accuracy of the model is relatively high.

In 2016, the State Administration of Coal Geology of China conducted a survey of geological exploration work in coal mines affiliated to various mining groups, and found that a large amount of original data has been accumulated in the fields of resource exploration, production exploration, and 3D seismic exploration in mining areas. With the production of coal mines, geological phenomena are constantly being revealed. , all kinds of geological data are also increasing. At present, these data are mainly stored in the form of two-dimensional maps and electronic documents. A large amount of coal mine data has not been effectively managed and integrated, resulting in the lack and lag of comprehensive research and other geological work. Geological work cannot play its due role in coal mine production. guiding role.
