Abstract: The application of underground pressure testing technology is analyzed and evaluated.It is proposed to establish a  microseismic monitoring system in mines adopting ARM embedded system and the conventional ground pressure system，and to use uninterrupted data information collection，three dimensional background analysis and networking technology transmission to realize a real time monitoring and forecastf deep ground pressure activity so as to timely and reliably guide the mine safety production.

Key words: Ground pressure monitoring, ARM embedded system, Micro-computer control, Network transmission
