Based on laboratory and full-scale (on-site) tests, the developed basic model of the MOÉD-Ip longitudinal-type multichannel optoelectronic deformometer appears to match its design specifications. Laboratory experiments using acoustic channels have demonstrated the unique possibility of application of individual measuring modules of the MOÉD-Ip instrument system for diagnosis and monitoring of the state of block media in terms of their loading stages. Based on full-scale (on-site) experiments in the Borok quarry, absolute deformations in rock mass due to blasts of different power under set conditions have been recorded for the first time. We believe that this technical development will find wide application in both mining and civil engineering for monitoring of the effect of blasts, earthquakes, and other factors on the state of natural or engineering structures. In this context, special stress should be laid on integrated application of deformographic and acoustic measurements. The procedure of processing and joint analysis of physical information proposed in this paper is indisputably novel and promising for practical applications.
We express sincere appreciation to V. I. Shut and V. K. Pakhotskii for their great help in constructing the MOÉD-Ip instrument system as well as to the specialists of the Novosibirskvzryvprom (Novosibirsk Blasting Industry) B. P. Raspopov, I. A. Aleksandrov, P. V. Kobelev, and V. N. Yurchenko for their help in organizing and performing on-site experiments at the Borok quarry.
