CN101363824 Device for real time monitoring mine roof rock formation or concrete structure stability.

The invention relates to a device for monitoring the stability of roof strata of a mine or concrete engineering in real time. The device mainly comprises a microseism signal conduction rod, a microseism signal sensing element and a microseism signal collection and analysis host computer. The microseism signal collection and analysis host computer is provided with a filter circuit for filtering the affection of ambient noise signal, a rapid data sampling circuit and a professional diagnosis and analysis software for analyzing the stability of the roof strata of the mine or the concrete structure in real time by utilizing artificial intelligence technology. The device is suitable for coal mines or other mines, can be used for the stability monitoring of underground construction which adopting concrete bar and concrete as the materials, such as metro stations or tunnels, and can also be used for the stability monitoring of dams, bridges, tall buildings and mountain landslides. Through a set of technology of digital filtering recognition and collection for the microseism signal, the recognition rate for acoustic signal released during rock breaking can be improved above 80 percent, and the purpose of monitoring the stability of the roof strata of the mine or the concrete structure is well completed.
