Embodiment Construction
[0033] The present invention will be further described below in conjunction with the accompanying drawings.
[0034] (1) Gas explosion
[0035] The gas explosion disaster (5) produces air shock waves and flames, wherein the air shock waves will destroy ventilation facilities, electrical equipment and casualties, and the rationality of the installation position of the emergency avoidance device (2) in mine disasters is of great importance to reducing the scope of the disaster (5) have an important role.
[0036] The scope of the overpressure caused by the air shock wave produced by the gas explosion disaster (5): the air shock wave overpressure value Δp of death is greater than 98KPa; the air shock wave overpressure value Δp of serious injury is 49-98KPa; the air shock wave overpressure value of moderate injury Δp is 29.4-49KPa; slight air shock wave overpressure value Δp is 19.6-29.4KPa; air shock wave overpressure value Δp is set at 19.6KPa for personnel safety overpressure ...

The invention discloses a method for determining the installation position of a mine disaster blocking emergency refuge device. The installation position of the mine disaster blocking emergency refuge device is obtained through calculation according to the relation between the distance between a gas blasting source and a protected object and the air shock wave overpressure value, and the rationality of the installation position of the mine disaster blocking emergency refuge device is verified through gas blasting flame propagation time, personnel evacuating time and the starting time of the mine disaster blocking emergency refuge device; aiming at a mine flooding accident caused by mine water inrush, the installation position of the mine disaster blocking emergency refuge device for preventing mine water inrush is determined through water level upward rising time, water flow downward pervasion time, the personnel evacuating time and the starting time of the mine disaster blocking emergency refuge device; the reference for determining the installation position of the mine disaster blocking emergency refuge device is characterized in that the personnel evacuating time Tr is longer than the starting time Tz of a photoelectric induction or impact sensor and the mine disaster blocking emergency refuge device, and the starting time Tz of the photoelectric induction or impact sensor and the mine disaster blocking emergency refuge device is not shorter than the maximum value of the flame propagation time TB and the water level upward rising time Ts in the gas blasting process.
Description
technical field [0001] The invention relates to a method for determining the installation position of a mine disaster blocking emergency avoidance device, which is mainly applicable to mines with risks of gas explosion, mine water inrush or local mine fire. Background technique [0002] According to Mei An Zi (1995) No. 50 "Reporting and Statistical Regulations on Casualty Accidents of Coal Industry Enterprises", the production casualties in the coal industry are divided into 8 categories, among which gas explosions, mine water inrush, and fires often cause mass deaths. Article 188 of the "Safety Regulations for Coal Mine" stipulates that in high-gas mines, outburst mines and mines with the risk of coal dust explosion, explosion-proof facilities should be installed on the driving face of coal lanes and semi-coal and rock lanes, but there is no clear explosion-proof facility. The specific location of the facility installation; the mine water inrush accident prevention equipme...
