Abstract
The article deals with the issues related to developing the hardware and software for a tool system for conducting full-scale investigations of the stress-strain state in rock mass. The problem solution using the temperature programming technique for drift compensation and exponential smoothing of signals from strain gauges is discussed. The mathware and software modules allow, during the in-situ rock stress measurements, to observe in real time the process of radial displacements of the measuring well contour while drilling and loading the parallel signaling well, as well as to store the original data in files for their office processing and archiving.
