Abstract: Many geologic hazards, such as rock burst, extrusive coal and gas, have an inevitable connection with microseismic in rock mass.Inspection on underground microseismic signal is a good way to determine the range and level of underground rock breaking to provide a powerful evidence for underground safety monitoring.Previous microseismic systems based on DSP or single chip can't reach the desired data collection due to its limitation, neither realize the advanced algorithm.The real-time microseismic monitoring system realizes the acquisition of multiple microseismic signals and the wavelet transform algorithm, which gives full scope to the advantages of virtual instruments.The monitoring result is much similar to actual rock burst and the error of location was minor to the defined upper limit, which means that the new system effectively completes the real-time monitoring and analysis on microseismic.

Key words: Microseismic signal, Data Acquisition, Virtual Instrument, Orientation, Real-time monitoring
