By the research on slumped mass changing process and regulation before and after the sudden outbreak, wireless transmission and automatic monitoring technologies are studied. BH-1 multi-parameter automatic monitor for slumped mass is developed for geological disasters forecast. Through the real-time monitoring on the physical properties and displacement morphology variation of the whole slumped mass and by the study on automatic monitoring technology, the whole course real-time monitoring on various physical and displacement morphology parameters of slumped mass are realized, which is important to the prognosis of slumped mass changing regulation.
