The method of increasing resistance adjustment has the advantages of simplicity, easy operation and quick effect, but it will increase the total wind resistance of the mine and reduce the total air volume. The drag reduction regulation method has the advantages of reducing the total wind resistance and increasing the total air volume of the mine, but the drag reduction regulation method has a large amount of work, large investment and long construction period.
It is more convenient to use the method of increasing energy (auxiliary ventilator) to construct, which can reduce the total wind resistance, increase the total air volume and reduce the energy consumption of mine ventilator. However, the equipment investment is large, the auxiliary ventilator consumes a lot of energy, the safety management is complex and the safety is poor.
Intelligent ventilation in mine is an operation which can supply fresh air to the mine for people to breathe continuously, stably and economically, dilute and discharge harmful gases and dust, improve the climatic conditions of the mine, and have certain intelligent control over airflow during disaster relief.
Main functions of mine intelligent ventilation system
The connotation of mine intelligent ventilation system is the deep integration of information collection and processing technology, control technology and ventilation system, which not only meets the automatic management and maintenance of daily ventilation, but also realizes emergency risk control in disaster period and effectively inhibits disaster evolution.
(1) The ventilation system is economical and reliable, and the disaster situation is forewarned, so as to achieve the safety and economic goals: ensure the reliability and economy of the daily operation of the ventilation system, and supply the air volume as required in the production process; Meet the automatic perception, diagnosis and early warning of abnormal ventilation.
(2) The whole process of ventilation system is automated, and the goal of intelligent regulation and control is achieved: the intelligent mine ventilation system is built by using Internet, Internet of Things, artificial intelligence, big data, new materials, advanced manufacturing, information communication and automation technologies, and the analysis, decision-making and linkage regulation are realized, so that the whole process of disaster prevention and mitigation, disaster control and active disaster relief is automated and intelligent.
