Description
Technical field
The present invention relates to a kind of coal-mine gas disaster distinguished and admirable monitoring analog demenstration system, be best suited for the distinguished and admirable demonstration of coal-mine gas disaster and simulation.
Background technology
Gas Disaster is the important disaster form of one in coal production operation, very easily causes the dead group of group to hinder event.Particularly after the Gas Disasters such as underground coal mine generation coal and gas prominent or gas explosion, pour out by gas or the impact of fire-heating air pressure, very easily cause the phenomenons such as the damage of wind path facility, distinguished and admirable adverse current, be difficult to determine that disaster gas is at distinguished and admirable effect following formula how diffusion And Movement, cause inconvenience to personnel in the pit's escape and accident rescue.Therefore, scene is needed a set of can the monitoring of research badly and is simulated the distinguished and admirable demo system of coal-mine gas disaster, for the generation and control thereof of understanding fire damp disaster provide theoretical and experimental basis, thus scientifically carry out Gas Disaster prevention and rescue work, with the life security of coal miner.
Summary of the invention
In view of the complicacy of relevant issues and the shortage of prior art, the object of this invention is to provide a kind of coal-mine gas disaster distinguished and admirable monitoring analog demenstration system, it can to go out when disaster gas after Gas Disaster occurs in down-hole how diffusion And Movement under distinguished and admirable effect by accurate simulation, for the prevention of Gas Disaster and rescue provide reference.
This analog demenstration system is primarily of compositions such as gas storage device, analog demenstration tunnel, disaster gas concentration/Pressure/Temperature sensor-based system, lamp line control system, data acquisition/process/display systems.
Concrete implementation step is: by being filled with disaster gas that is a certain amount of and certain pressure instantaneously in simulation tunnel, the Gas Disaster that simulation underground coal mine occurs, by the migration spread condition of the concentration of arranging in pipeline, pressure sensor monitoring disaster gas, and shown in real time by computing machine; Simultaneously, lamp line is laid by the pipeline that may flow through at each joint disaster gas, and the gas density threshold value that the light on and off state of lamp is transmitted by firedamp sensor determines, and automatically controlled by controller, therefore, the glittering order of lampet can be utilized, the in-position of demonstration disaster gas entrainment, and then the more vivid migration with describing distinguished and admirable Gas Disaster intuitively can cause calamity process.
A kind of coal-mine gas disaster of the present invention distinguished and admirable monitoring analog demenstration system, is best suited for the distinguished and admirable demonstration of coal-mine gas disaster and simulation.The migration rule accurate and effective of disaster gas under distinguished and admirable effect after this system simulation fire damp disaster, for the generation and control thereof of understanding fire damp disaster provide theoretical and experimental basis, a whole set of experimental system method of operating is simple, the influence factor that can simulate comprehensively, demonstrate visual result, there is good practicality.
Embodiment
Below in conjunction with the embodiment of in accompanying drawing, the invention will be further described:
