Abstract:

The automatic monitoring system can monitor and warn of mine pressure and movement in underground mines. The data collected by advanced measuring equipment is objective, reflects the actual situation in the tunnel and rock mass, and provides a practical basis for making timely decisions and solutions in production and for scientific research. No-pillar mining technology has been applied in longwall I-10-9, Khe Cham I area of Ha Long Coal Company since 2022, which can be assessed as successful so far.In particular, the automatic monitoring system KJ520, with its many advantages and suitable measuring devices, has promoted its working efficiency, contributing to the success of the technology.
