Mine ventilation system partitioning stabilized dynamic monitoring and pre-warning system

Abstract

The invention discloses a mine ventilation system partitioning stabilized dynamic monitoring and pre-warning system. The mine ventilation system partitioning stabilized dynamic monitoring and pre-warning system comprises an underground information collection system, an information management analysis system and an alarm system. Ventilation monitoring equipment is mounted at key underground branched monitoring sites, monitored related information is transmitted to a ground monitoring center by the ventilation monitoring equipment, unified management is carried out on data by programs, pre-warning values are set and are set in the programs in combination with underground field measurement and dynamic network calculating result; when underground measured data exceeds the pre-warning values, an alarm is given in ground or underground areas, and the data size is monitored according to monitoring points of each area so as to analyze occurrence reasons and positions of catastrophes. According to the system, underground monitoring areas are reasonably distributed, so that the distribution amount of underground monitoring measuring points is reduced, the control process is simple, practical, safe and reliable, and the whole control system is low in investment and high in operability.

Description

technical field [0001] The invention relates to a mine ventilation dynamic monitoring and early warning system, in particular to a mine ventilation system partition stable dynamic monitoring and early warning system, which belongs to the field of coal mine ventilation safety. Background technique [0002] The safety and stability of the mine ventilation system is the premise of underground safety production work. Since the underground ventilation and exhaust are always in the process of dynamic changes, the establishment of an underground ventilation network with a reasonable layout and strong anti-interference ability, and real-time monitoring of the mine ventilation network The importance of monitoring and timely adjustment to ensure safe production is self-evident. It can be seen from the statistical research on disaster prevention accidents in coal mines that coal mine disasters often originate from a certain part of the system and are caused by the abnormal development ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem that the present invention needs to solve in order to achieve the above purpose is how to reasonably carry out the regional monitoring layout of the mine, starting from the integrity of the mine ventilation system, and ensuring the safe and stable operation of the mine ventilation system with fewer monitoring points, so as to solve the current situation. There are technical problems in mine safety monitoring system, such as complex layout of monitoring measuring points, weak expansion ability, inconsistent database, and low reliability
