Description

technical field [0001] The invention relates to the technical field of mine ventilation, in particular to a mine ventilation monitoring and remote control system and an intelligent decision-making method. Background technique [0002] Mine ventilation system is one of the important systems to ensure safe production in coal mines. It is responsible for sending sufficient fresh air to underground working sites, diluting and discharging toxic and harmful gases, dust and heat and humidity underground. The mine ventilation system is composed of the shaft ventilation network determined by the ventilation mode, the main ventilator driving the air flow, and the ventilation structures controlling the air flow. A reasonable mine ventilation system is the most important link to ensure safe production in mines, improve the labor safety and health conditions of underground personnel, and prevent and fight disasters. In order to ensure the safe, stable and economical operation of the ven...

Problems solved by technology

[0003] However, the parameters of the mine ventilation system change in real time with the succession of mine excavation projects. The workload of manual measurement of ventilation parameters is huge, and it is difficult to obtain real-time and accurate ventilation parameter data of the mine ventilation system, making it difficult for ventilation managers to detect in time. System safety hazards affect the formulation of countermeasures, thereby increasing the probability of hidden dangers turning to accidents

The measurement cost and implementation difficulty of the manual measurement method are relatively large, and the requirements for real-time dynamic measurement of the air flow parameters of the ventilation network cannot be realized.
