New Sensor Technology for Determining Rock Pre-destructive States

Based on the experimentally discovered regularity – emission of micro-sized particles during monoaxial deformation non-homogeneous structures, such as rocks and concretes, a sensor technology to identify their pre-destruction processes is proposed. At nearing stressed state until disintegration massifs, exponential increase generation appears. The innovation applicable risky rock formations where vertical measurement boreholes are made, by which kernels obtained. Using specimens formed kernels, through load press in laboratory conditions corresponding particle emissions, reference pressure values for different stages pre-destructive development determined. data from compared with results loads structure, generated borehole model. stress determine occurrence critical states structure. This information an integrated indicator timely identification rocks. described system increases accuracy determining appearance failure conditions. One strategic applications new seismically active regions.
