The mining techniques are based on the computer supported cooperative work using a real-time mine-monitoring system. Without this system associated RF wireless network, the safety, and security of mineworkers cannot be understood and ascertained. This paper proposes a mine auxiliary sensor system (MASS) will effectively monitor all situations in mine especially for the safety of mineworkers. The implementation results indicated that real-time mine auxiliary monitoring system (RMAMS) standard is adopted for a real-time mine-monitoring system. D-ASK and D-FSK can satisfy requirements for different environment more than other communication protocol.
