Problems solved by technology

[0004] There are many coal mines in our country, and gas accidents occur frequently. To study the impact of the gas explosion, what kind of damage it can cause, what degree of damage, and whether the mine is strong enough, these require advanced test equipment for simulation and analysis. Most of the experimental devices are relatively primitive or relatively simple, and the basis for judging is whether the explosion-proof membrane has burst, how many layers have burst, and the state of the burst, etc. It is difficult to study the specific situation of the explosion impact based on this

Description

technical field [0001] The invention relates to the technical field of blasting test devices and methods, in particular to a specially designed gas explosion impulse detection device and detection method. Background technique [0002] Coal and gas outburst is one of the most serious disasters in coal mining in my country. The dynamic effect produced when the outburst occurs can destroy the production system, cause casualties, and easily cause major accidents such as coal dust and gas explosions. Therefore, in order to minimize the destructive effects of disasters, it is necessary to study the disaster-causing mechanism of coal and gas outbursts and explore effective disaster control methods and measures. [0003] Due to the complexity of coal and gas outburst and the limitations of research methods and means, there are few theoretical studies on the disaster-causing theory of coal and gas outburst at home and abroad. There are insurmountable difficulties in laboratory simu...
