Abstract

In order to improve the safety and reliability of the ventilation system, the ventilation resistance monitoring and situation analysis methods of the ventilation path are used to diagnose the changes in mine ventilation resistance in real time and determine whether the ventilation system is healthy. Calculate the mine safety monitoring path through the critical path determination algorithm, and install multi parameter sensors (wind pressure, wind speed, temperature, humidity) in the critical path roadway. Real time calculation of mine resistance based on the barometer base point method and saving of historical monitoring parameters. By filtering out data and fitting trend curves in a two-dimensional coordinate system, the subsequent ventilation resistance is predicted using the cubic exponential smoothing method. This provides technical support for real-time control of the impact of changes in mine resistance caused by geological disasters on the mine ventilation system, and provides scientific management tools and advanced technological means for mine ventilation gas safety management and production safety.
