Mine ventilation system based on coal mining

Abstract

The invention provides a mine ventilation system based on coal mining. The mine ventilation system comprises a plurality of monitoring modules, an air inlet fan, an air inlet shaft, a plurality of shutter air inlet modules, a plurality of atomization spraying modules, an air return shaft, an air return fan and a remote controller. The plurality of monitoring modules are installed on the top of the well wall of a mine, and each monitoring module is in bidirectional communication connection with the remote regulator. Various concentrations of air in a mine are monitored through the monitoring module, the air inlet amount of the shutter air inlet module is adjusted through the remote controller according to data monitored by the monitoring module, the ventilation amount in the mine can be adjusted, the atomization spraying module is controlled through the remote controller to conduct atomization spraying, and the spraying efficiency is improved. The spray can flow into the mine along with air, and is combined with various hazardous gases in the mine to settle, so that the hazardous gases can be diluted and settled in the circulation process, and the inflammable and explosive conditions of the gases in the circulation process are avoided.

Description

technical field [0001] The invention belongs to the technical field of mine ventilation, and relates to a mine ventilation system based on coal mining. Background technique [0002] Mine ventilation refers to entering fresh air into the mine to increase the oxygen concentration to dilute and remove toxic and harmful gases and dust in the mine. The basic task of mine ventilation is to supply enough fresh air underground to meet the oxygen needs of personnel and Harmful gas and dust in the well, to ensure safe production, adjust the climate in the well, and create a good working environment. Among them, the extraction ventilation is one of the ventilation forms, which is to enter the fresh air from the roadway into the working face, and the fan is passed through the air duct by the bureau. fan out. [0003] However, there are some shortcomings in the mine ventilation system in the form of extraction in the market at present. The traditional mine ventilation system cannot adju...

AI Technical Summary

Problems solved by technology

[0003] However, there are some shortcomings in the mine ventilation system in the form of extraction in the market at present. The traditional mine ventilation system cannot adjust the air volume during the working process. , The ventilation efficiency of the traditional ventilation system is relatively low, and it cannot quickly and effectively reduce the concentration of various dangerous gases in the mine. During the circulation of dangerous gases, it is very easy to cause flammable and explosive situations that endanger the staff.
