Experimental tests of a multichannel optoelectronic longitudinal deformometer

Test results are presented for a multichannel optoelectronic longitudinal d eformometer MOED-1p at the "Oktyabrsky" mine of the Norilsk deposit with wh ich rock strains and displacements were monitored around an observation wor king located in the area of a tectonic fault. Basic versions are developed for installing the transducers of the instrument with fixing of the datum-m ark support both within the depth of the rock mass and also at the side wal l of the working. A relationship is established between the designed techni cal and actual characteristics of the instrument.
