Product Introduction

The KJ1235 Coal Mine Impact Ground Pressure Monitoring System integrates ground sound, high-frequency electromagnetic radiation, low-frequency electromagnetic radiation, and microseismic monitoring functions. It can monitor the changes in coal and rock mass signals under load in real time. It can be used for underground coal mine rock burst monitoring and early warning, dynamic disasters such as coal and gas outbursts, mine pressure evaluation, water gushing-out monitoring and early warning, mining impact monitoring, roof collapse monitoring, and mining crack evolution monitoring.
