Tunnel surrounding rock disaster emergency plan system and method based on virtual reality

Abstract

The invention relates to a tunnel surrounding rock disaster emergency plan system based on virtual reality. A monitoring terminal is arranged in a tunnel; thermal infrared temperature measurement probes, microseism sensors and acoustic emission sensors are fixedly mounted in the tunnel. The thermal infrared temperature measurement probes, the microseism sensors and the acoustic emission sensors are connected with the monitoring terminal through wireless devices. The monitoring terminal is connected with a real-time three-dimensional computer out of a mine through a wired optical cable. The real-time three-dimensional computer is connected with a VR terminal. The invention also discloses a tunnel surrounding rock disaster emergency plan method based on virtual reality. The system and the method have the advantages that staff can view the top plate surrounding rock condition of any place and any time within a monitoring area in real time whenever and wherever possible; observers no longer needs to enter the mine; the system and the method relate to multisource physicochemical information of tunnel surrounding rocks; the information amount is high; the data is fed back timely; and the accurate information for forecasting a surrounding rock disaster can be provided.

Description

technical field [0001] The invention relates to the technical field of surrounding rock roadway early warning, in particular to a virtual reality-based emergency plan system and method for roadway surrounding rock disasters. Background technique [0002] How to safely and effectively predict (report) roadway surrounding rock hazards is still an urgent task for mining enterprises. With the depletion of shallow mineral resources, the development of mine resources is gradually moving towards deep mining, and the surrounding rock environment of the stope has undergone significant changes, resulting in a significant increase in the scale, frequency, and degree of hazards of roadway surrounding rock disasters. Prevention and control has been one of the major scientific problems that have seriously restricted mine safety construction and scientific mining. Therefore, it is urgent to seek an accurate and real-time surrounding rock disaster prediction (report) decision-making system...

AI Technical Summary

Problems solved by technology

[0005] (1) The existing technology cannot realize real-time monitoring in the true sense, and the monitoring results have obvious lag. The collected data generally need to be fed back from the underground to the processing center on the ground, and the results will be given after manual or computer analysis. Considering Due to the uncontrollability of human factors, there is generally an obvious time interval between the data output point and the data collection point

[0006] (2) Existing technologies are highly specialized and require professionals to collect and analyze data

In most cases, traditional monitoring methods for surrounding rock disasters require downhole drilling, and the labor cost is high

[0007] (3) The data obtained by the existing technology generally have obvious regional characteristics, which can only reflect the situation of the monitoring section, and do not have global and dynamic characteristics

[0008] (4) The data readability of the existing technology is poor, and ordinary people cannot accurately judge the cause and location of the surrounding rock disaster

[0009] (5) On-site monitoring still requires personnel to go down the well, and there are certain potential safety hazards
