The utility model relates to a stone stability monitoring technique, especially a portable stone stability sound transmission continuous monitoring instrument. Because currently everyday used human monitoring sound transmission monitoring instrument adopts LED (light emission diode) digital indication, the collected stone sound transmission signal needs to be recorded manually in field, non storage portion and analysis processing system is included. The utility model comprises memories connected on the output ends of the sensors, performs all-day long-term continuous collection monitoring to characteristic parameters such as number of sound transmission events, number of big events, sound transmission ratio or the like in the stone or concrete structure, has characteristics of convenient parameter adjustment and use, high stability and reliability, and is capable of performing safety stability monitoring to top boards of mines, mine column, surrounding stones, and stone or concrete structures such as side slo
