The mine pressure on-line monitoring and training system consists of mine pressure big data on-line monitoring instruments and meters that have obtained national mine product safety marks and multiple generator devices that realize the load-carrying work of mine pressure monitoring substations. Under the condition of intrinsic safety, the main mine pressure manifestations (support working resistance, roof separation value, bolt force and coal borehole rock stress) of coal mining face and roadway are simulated to the maximum extent, it realizes the similarity between the monitoring substation under laboratory conditions and the load on the coal mine site, and can meet the basic functions of recording, displaying and exporting real-time and historical mine pressure manifestation data, online transmission and infrared acquisition, which provides data support for the writing of mine pressure monitoring experimental reports.
