The utility model discloses a
coal mine
pressure data combined
monitoring system. Comprising a multi-point displacement meter installed in a
coal mine tunnel top plate in a drilling mode, an anchor rod
dynamometer installed on an anchoring part of the
coal mine tunnel top plate or / and a tunnel side wall,
laser displacement meters fixedly installed on the two sides of a coal
mine tunnel bottom plate or / and the tunnel side wall, and a drilling stress meter installed in the coal mine tunnel side wall in a drilling mode. The multipoint displacement meter, the anchor rod
dynamometer, the
laser displacement meter and the borehole stress meter are respectively in communication connection with the
data acquisition instrument, the
data acquisition instrument is in communication connection with the underground monitoring
information processor, and the underground monitoring
information processor is in communication connection with the ground monitoring
server. According to the utility model, the
integrated monitoring of various mine
pressure data of the coal mine tunnel is realized, the coal
mine safety production is guided, the
system is suitable for coal mine tunnel monitoring under different geological conditions, the
data processing cost of coal
mine safety monitoring is reduced, accidents caused by coal mine
rock burst disasters are reduced, and the underground coal
mine safety production is guaranteed.
