Digital mine tunneling search prediction method

Abstract

The invention relates to a digital mine tunneling search prediction method. Engineering geological data including tunnel data, mine data, databases and the like of mines are imported into a data cache region of a processor through input equipment, and integration of tunnel data of mines is completed by interface tools. A three-dimension tunnel structure is built by the aid of an interactive tool, tunneling is performed while tunnel attributes are established, and tunnel network topological structure is built for complicated mining areas. By the digital mine tunneling search prediction method, tunneling of actual engineering or simulated tunnel mining can be realized, and the optimal path of tunnels can be searched according to factors of tunnel length, tunnel geological structure change, geological structural characteristics, stability of surrounding rocks, water inrush property, gas emission and the like, so that risk prediction is realized and risk can be lowered. In addition, the digital mine tunneling search predication method is easy to popularize to applications for underground tunnels and pipelines, blow-off pipelines, underground rivers and the like, provides more visual digital information for underground engineering, and improves accuracy and reliability of data of geological exploration.

Description

technical field [0001] The invention relates to a method for searching and predicting roadway excavation in mines, in particular to a method for searching and predicting roadway excavation in digital mines. Background technique [0002] Digital mine is to establish a virtual mine with multi-resolution and three-dimensional dynamic expression, which makes profound changes in the methods of acquiring, storing, processing and displaying mine data. Through the digital mine, the natural geography, ecological environment, ore deposit geology, mine construction, excavation, mining, dressing, etc. of the mine can be digitized, informatized, intelligent, networked, and visualized, making mine planning and design more efficient and more expressive. Rich and more information can greatly improve the real-time and effectiveness of mine construction, safety monitoring and enterprise management. [0003] At present, the underground geological conditions of my country's coal mines are comp...

Problems solved by technology

[0005] The technical method of roadway excavation in the prior art mainly has the following problems: use the extracted three-dimensional coordinates of the wire points as the data source, use the vertices of each section in 2D or the Weiler-Atherton polygonal clipping algorithm to carry out three-dimensional modeling of the roadway, and adopt a complex tree-shaped storage structure, which wastes Space, in the case where two polygons are included or separated from each other, redundant intersection calculations are generated, the time complexity is high, and some special intersection points cannot be processed correctly; use section objects and cylinder-like surfaces to express mine roadway phenomena or pass through roadways. , lower distance and left and right distances to express the spatial form of the roadway, then the roadway space network cannot be formed or the three-dimensional spatial graphic data of the roadway engineering cannot be automatically generated

In addition, with the development of 3D modeling technology and the wide use of modeling software, it is more and more common to make roadways based on 3D modeling tools such as 3DMAX, MAYA, AutoCAD, etc. However, this method is usually not compatible with the ore body structure model Combined, it cannot reflect the geological environment changes of the surrounding rock ore body structure during the excavation process; although the three-dimensional point cloud data obtained by the scanner can directly establish the roadway model, the spatial shape is realistic, but there is still a lack of effective description of the roadway. Due to the lack of search and prediction functions for complex roadways, it cannot meet the needs of rapid development of mine construction.
