Embodiment Construction

[0039] Such as figure 1 As shown, the method for judging the secondary gas explosion in the mine thermodynamic disaster rescue process of the present invention comprises the following steps:

[0040] Step 1. Determine the location of the secondary gas explosion: install regional monitoring nodes 1 at multiple key locations in the mine to collect temperature parameters in the corresponding areas and transmit the temperature parameters in this area to the control computer 3 installed in the monitoring room in real time , setting the temperature parameter threshold through the keyboard input module 2, using the control computer 3 to calibrate the key position that reaches the temperature parameter threshold, and predicting the location where the secondary gas explosion occurs;

[0041] The regional monitoring node 1 includes a regional controller 1-6, a clock circuit 1-5 and a communication module 1-7 connected to the regional controller 1-6, and the input terminal of the regiona...

Abstract

The invention discloses a method of judging secondary gas explosion in mine thermodynamic disaster relief; the method comprises the steps of I, determining a secondary gas explosion position; II, estimating time for secondary gas explosion to occur in the monitored area, to be specific, 201, acquiring environmental parameters of the monitored area, 202, judging whether the monitored area is an area experiencing high-concentration gas explosion or not, 203, estimating time and probability for the high-concentration gas explosion to occur and 204, estimating time and probability for low-concentration gas explosion; III, estimating time for the secondary gas explosion to occur in the monitored area; IV, displaying and storing in real time, judgment results for the secondary gas explosion. The method of the invention is novel in design, can judge the three key indexes, time, probability and position, of secondary gas explosion in a coal mine, and can provide theoretical reference and guidance for commanding and decision-making for thermodynamic disaster relief.

Description

technical field [0001] The invention belongs to the technical field of mine thermodynamic disaster rescue, and in particular relates to a secondary gas explosion determination method in the mine thermodynamic disaster rescue process. Background technique [0002] The evolution mechanism of mine fires and gas explosions in thermal and dynamic disasters in coal mines is extremely complex, and a variety of secondary disasters may occur during the rescue process, such as roadway roof fall, high temperature heat damage, high concentration smoke, open flame fires, gas and coal dust explosions , disordered wind flow, large amounts of toxic and harmful gases, damage to the ventilation system, etc. As the implementers of mine rescue work and the frontline personnel in danger of disaster relief, the personal protective equipment of rescuers usually only protects them from the threat of toxic and harmful gases, but has little protection against gas explosions. During the rescue proces...
