Embodiment 1

[0080] Such as figure 1 As shown, this embodiment discloses a virtual emergency drill method for coal mine gas explosion disaster, and the specific implementation steps are as follows:

[0081] Step 1: Determine the basic parameters of the mine site.

[0082] Step 1.1: On-site investigation to determine the mine roadway layout and key equipment, determine the roadway size, support type, key equipment size, and working conditions. The support types include shed support, stone support, bolt support and shotcrete support. The working conditions are as follows: work when the gas concentration is less than 1%, and stop working when the gas concentration is greater than or equal to 1%.

[0083] Step 1.2: On-site investigation of the mine to determine the size, installation location and working conditions of the gas concentration sensor in the shaft roadway. The working conditions are as follows: the gas concentration value is displayed according to the rising rate of the gas conc...

Embodiment 2

[0110] Such as figure 2 As shown, a virtual emergency drill system for coal mine gas explosion disaster disclosed in this embodiment includes a mine site basic parameter database module, a gas explosion numerical simulation module, a virtual reality basic scene sub-module for establishing a coal mine gas explosion disaster, an initialization module, and an emergency drill And escape training module, effect evaluation module, improvement and optimization module.

[0111] The basic parameter database module of the mine site is used to determine the basic parameters of the mine site.

[0112] The gas explosion numerical simulation module is used to numerically simulate the gas explosion in the typical high-concentration gas area of ​​the mine and evaluate the area affected by the explosion.

[0113] The sub-module of establishing the basic virtual reality scene of coal mine gas explosion disaster is used to establish the basic virtual reality scene of coal mine gas explosion di...

Abstract

The invention discloses a coal mine gas explosion disaster virtual emergency drilling method and a system thereof, which belong to the field of disaster prevention. The method of the invention uses avirtual reality technology to construct a virtual coal mine gas explosion disaster emergency drilling scene, and uses an input device to realize the interaction between the multi-user and the virtualscene, obtains the experience of the coal mine gas explosion disaster virtual emergency drilling close to the real gas explosion, and achieves good emergency drills and training results. The system ofthe invention comprises a mine on-site basic parametric database module, a gas explosion numerical simulation module, a coal mine gas explosion disaster virtual reality basic scene-building sub-module, an initialization module, an emergency drill and escape training module, an effect evaluation module, and an improved optimization module. The method and the system have the engineering applicationvalue in the field of the coal mine gas explosion disaster rescue training, can improve the relevant rescue knowledge level and escape ability of the mine staff, improve the escape and rescue efficiency, and reduce the loss.

Description

technical field [0001] The invention relates to a virtual emergency drill method and system for coal mine gas explosion disasters, in particular to an emergency drill method and system for real experience coal mine gas explosion disasters that can be interactively participated by multiple people, and belongs to the field of disaster prevention. technical background [0002] In recent years, with the gradual deepening of my country's coal mine safety production work, the overall safety production level of coal mines has been greatly improved, and coal mine safety production has shown an overall stable and improving development trend. Nevertheless, the situation of safe production is still grim, and one of the important aspects is the gap with the level of emergency training and emergency rescue work for employees in developed countries. [0003] In the "Opinions of the State Administration of Work Safety on Accelerating the Construction of National and Regional Mine Emergency...
