THE DEFORMATIONAL MODE OF COMPLEX DETERMINATION OF DEFORMED STATE AND STRENTH CHARACTERISTICS OF MINING AND CONSTRUCTION OBJECTS

Abstract

The purpose of complex mode consists in increasing efficiency of nature studies of mining and construction objects stressed-deformed state. The essence is in jointed application the measurements of three kinds of deformations on ring slot:

1 – partial rock mass disloading on the slot; 2 – complete kern disloading; 3 – deformations in the kern by on-step fixed load guiven in central blast hole. The results are applied in calculations physical and mechanic rock mass properties in the given site; the value and direction of principle stresses and as a result for determination the stable object’s paramet
