The utility model relates to the technical field of
coal mine underground operation auxiliary equipment, in particular to a modularized
coal mine underground goaf
safety monitoring device, and mainly solves the technical problem that in the prior art, a
coal miner carries too many monitoring auxiliary equipment during operation. The modularized
safety monitoring device for the underground goaf of the coal mine comprises an early warning host which is provided with at least two mounting positions and a plurality of data interfaces; the monitoring instrument comprises a module base, an instrument body and a data line; and the
buzzer is arranged at the top of the early warning host and is in communication connection with the early warning host. The monitoring instrument of the device is detachably fixed on the front side wall of the early-warning host and is in communication connection with the
data interface of the early-warning host through the data line, so that a proper monitoring instrument can be selected according to actual conditions, a plurality of monitoring instruments can be integrated on the same early-warning host and share the same early-warning host, and the monitoring efficiency is improved. And the
overweight workload caused by carrying a plurality of independent instruments by a worker can be effectively avoided.
