A self-vibrating type micro-quake
monitoring system comprises a ground central
station, a control host computer, network switches, monitoring substations, vibration pickups and a self-vibrating source, wherein the ground central
station is used for receiving data and storing the data in real time; the control host computer is used for presetting and modifying relevant parameters of monitoring indexes, receiving the data and preprocessing and analyzing the data; the network switches are used for transmitting the data in the well and above the well; the monitoring substations are used for acquiring and judging input signals, performing analog-
digital conversion to the signals, amplifying signals, eliminating
signal superposition and automatically recognizing the signals meeting preset parameters; the vibration pickups are used for picking up a natural
cracking signal of
coal and rock
mass and a
signal transmitted from the self-vibrating source and transmitting the signals to the monitoring substations; the self-vibrating source is used for generating an artificial
P wave, correcting speed of the
P wave generated by the natural
cracking signal and correspondingly valuing the speeds of the P
waves of the vibration pickups distributed in different areas. The self-vibration type micro-quake
monitoring system is simple in structure, easy to operate, high in quake data computation precision and convenient for monitoring in large-range, long-term and dangerous conditions.
