The invention discloses a mine ventilation network abnormity diagnosis simulation experiment system and method. The system comprises a supporting bracket, a mine ventilation power simulation subsystem, a mine ventilation network simulation subsystem, an abnormal event triggering subsystem and a monitoring data collection subsystem. Assembling simulation is carried out according to the layout position of the ventilation network in the actual mine, single experiments of various conditions such as gas outburst or gas emission simulation, air leakage simulation, roadway collapse and narrowing simulation and ventilation power abnormity simulation can be carried out, and then the abnormal positions of the mine ventilation network under various single conditions can be determined; and at the same time, at least two of the above conditions can be experimented at the same time, thereby obtaining the abnormal position of the mine ventilation network under the integration of various conditions, finally determining the influence of various simulated abnormal events on each position of the mine ventilation network, and therefore, corresponding abnormal event positions can be obtained through timely diagnosis when ventilation abnormity occurs at each position of an actual mine ventilation network.
Description
technical field [0001] The invention relates to a mine ventilation network abnormality diagnosis model, in particular to a mine ventilation network abnormality diagnosis simulation experiment system and method. Background technique [0002] Mine ventilation refers to the continuous input of fresh air from the ground to the various working places in the underground, to provide personnel with breathing, and to dilute and eliminate various toxic and harmful gases and dusts in the mine, to create a good working environment in the mine, and to ensure the health of underground workers. health and occupational safety. Its basic task is to provide enough fresh air for each working place in the underground, so that the concentration of toxic and harmful gases and mine dust in the underground air does not exceed the specified value, and mine ventilation is the most effective and economical way to prevent and control gas, fire, dust and other disasters. And the most direct means, if p...
