System and method for mine cataclysm ventilation distributed area linkage and intelligent control

Abstract

The invention discloses a system and method for mine cataclysm ventilation distributed area linkage and intelligent control. The system comprises a ground remote monitoring center, an industrial Ethernet communication system, an air and smoke flow intelligent adjusting device and an underground distributed area linkage monitoring system. When communication is normal, air and smoke flow area linkage and intelligent control are realized through a ground remote instruction; when communication is abnormal, a multivariate factor cross study and judgment technology is adopted, and cross perception and state study and judgment are achieved according to the communication state between stations, the remote instruction, temperature, CH4, CO and O2 concentrations in smoke and air and smoke flow components and other multivariate information. A decision tree learning method is used, a multivariate factor tree model is established, and by means of data mining and multivariate factor cross analysis and judgment of area monitoring information, independent decision-making type cataclysm air and smoke flow area linkage and intelligent control are achieved. By monitoring ventilation parameters and environment parameters in real time and achieving intelligent control over a whole ventilation system, various disasters and accidents caused by abnormal ventilation can be effectively prevented.

Description

technical field [0001] The invention belongs to the field of coal mine catastrophe wind and smoke area linkage monitoring, and in particular relates to a mine disaster ventilation distributed area linkage and intelligent control system and method. Background technique [0002] Coal is the main energy source in our country. With the large-scale mining of coal resources in recent years, deep mining has become an inevitable trend in the development of the coal industry. At the same time, the prevention and control of various safety problems in deep mining has become the difficulty and focus of mine management. The anti-catastrophe ability of mine ventilation system refers to the comprehensive ability of the system in gas discharge, fire prevention, cooling, disaster relief, etc., as well as whether it has a reliable ventilation system, independent safety exits, disaster avoidance routes and other safety measures. However, my country's mine catastrophe ventilation distributed au...

AI Technical Summary

Problems solved by technology

The confined space underground in the mine itself is not suitable for escape, and the complex wind network structure of the mine will cause psychological panic and increase the difficulty of escape

The existing research results are still not clear about the basic theories such as automatic regulation of mine wind and smoke flow, regional linkage and coordination of catastrophic wind and smoke flow, and lack of in-depth theoretical guidance on the control mechanism of mine catastrophic wind and smoke flow and the configuration method of regional linkage devices. Unable to meet the urgent needs of my country's mine disaster emergency rescue mode
