Embodiment 1

[0070] Such as figure 1 As shown, this embodiment discloses a virtual simulation and emergency escape training method for fire accidents outside the mine, and the specific implementation steps are as follows:

[0071] Step 1: Determine the basic parameters of the site in the flammable area caused by fire outside the mine.

[0072] Step 1.1: Through on-site investigation and analysis of mine data, determine the flammable substances, flammable locations, heat Q and CO concentration C production rates in the flammable area caused by the fire outside the mine. The flammable substance includes a belt, and the flammable location includes a belt machine head and a belt machine tail.

[0073] The calculation formula of the heat Q: Q=Vh×Vb×W

[0074] Among them, Vh is the heat release rate, when the belt is on fire, the value of Vh is 50KW / m 2 to 100KW / m 2 Between; Vb is the average burning rate, when the belt is on fire, the value of Vb is between 0.1m / s and 1m / s; W is the width o...

Embodiment 2

[0096] Such as figure 2 As shown, the mine external fire accident virtual simulation and emergency escape training system disclosed in this embodiment includes a mine site basic parameter database module, a fire accident numerical simulation module, a mine external fire virtual reality basic scene construction module, and an emergency drill and escape training module. , effect evaluation module, improvement and optimization module.

[0097] The basic parameter database module of the mine site is used to determine the basic parameters of the mine site.

[0098] The basic parameter database module of the mine site includes the roadway layout and key equipment parameter sub-module, the CO concentration sensor parameter sub-module, the emergency broadcast parameter sub-module, the compressed air self-rescue station parameter sub-module, and the refuge chamber parameter sub-module.

[0099] The roadway layout and key equipment parameter sub-modules are used to realize on-site inv...

Abstract

The invention discloses a virtual simulation and emergency escape training method for a mine external-cause fire accident and a system thereof, which belong to the field of disaster prevention. The method of the invention uses a high-precision numerical simulation and virtual reality technology to construct a virtual external-cause fire accident emergency drilling scene, and uses an input device to realize the interaction between the multi-user and the virtual scene, obtains the experience of the mine external-cause fire accident virtual emergency drilling close to the real fire accident, andachieves good emergency drills and training results. The system of the invention comprises a mine on-site basic parametric database module, a fire accident numerical simulation module, a mine external-cause fire accident virtual reality basic scene-building 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 application value in the field of the mine external-cause fire accident, can improve the relevant rescue knowledge level and escape ability of the mine staff, improve the escape efficiency of the underground workers when the mine disaster occurs, and reduce the casualties.

Description

technical field [0001] The present invention relates to a method and system for virtual simulation and emergency escape training of mine external fire accidents, in particular to a virtual simulation method capable of simulating the real scene of mine external fire accidents and an emergency drill method for real experience of mine external fire with interactive participation of multiple people and systems, belonging to the field of disaster prevention. [0002] technical background [0003] Coal is the main energy source in my country, accounting for about 70% of China's primary energy consumption structure. The national raw coal output has also increased year by year, from 1 billion tons in 2000 to 3.65 billion tons in 2012. According to the national energy plan, it is estimated that by 2015, the total national energy consumption will reach 4.1 billion tons of standard coal, of which the total coal consumption will reach 3.8 billion tons, accounting for about 64% of the pr...
