Real-time microseismic monitoring system and monitoring method for coal mines

Abstract

The invention belongs to a coal mine safety monitoring device, and particularly relates to a real-time microseismic monitoring system and monitoring method for coal mines. An industrial Ethernet ring network (11) is connected with a ground switchboard (4) above the ground and an underground switchboard (4-1), the ground switchboard (4) is respectively connected with a timing system (2), a central control machine (1) and a parameter database (10), the underground switchboard (4-1) is connected with four underground monitoring hosts (3), each underground monitoring host (3) is connected with four terminal boxes (5) by signal lines (8), one of the terminal boxes (5) is connected with an underground power supply (7) by using a sensor supply line (9), and each terminal box (5) is connected with an acceleration sensor (6). By using the real-time microseismic monitoring system and monitoring method for coal mines, disclosed by the invention, the intelligent identification and extraction of microseismic signals of coal mines can be realized, and a terminal device can implement remote control, therefore, the system and method disclosed by the invention have the characteristics of flexibility, reliability, good monitoring effect and small investment.

Description

technical field [0001] The invention belongs to coal mine safety monitoring equipment, in particular to a coal mine microseismic real-time monitoring system and monitoring method. Background technique [0002] A mine earthquake is a mine earthquake induced by mining, and it is a natural disaster in a mine. When a mine earthquake occurs, the surrounding rock releases energy rapidly, and the coal rock is suddenly destroyed in an instant. Disasters such as roadway blockage, ground shaking, house damage and personal casualties. [0003] At present, the technology of predicting and controlling mine shock is being studied at home and abroad. Although the mechanism of mine shock has been understood and some preventive measures have been taken, it has not been well resolved. At present, most of the researches are devoted to a certain phenomenon of mine earthquake. Most of the mines in my country were built in the 1950s and 1960s. At present, these mines are about to enter deep min...

AI Technical Summary

Problems solved by technology

For mine earthquake disasters, especially coal mine microseismic real-time monitoring equipment, at present, the monitoring data cannot be automatically recorded and stored when the transmission fails, and the monitoring data can be remotely controlled and sent in real time. It cannot achieve flexible and reliable monitoring and avoid accidents. purpose, some monitoring equipment requires a large investment
