Mechanical Characteristics of Rocks at Low Temperatures

Abstract

In the case of underground storage of L. N. G., it is important to know the mechanical characteristics of rocks at low temperatures.
In this study, the physical and the mechanical properties of dry and wet rocks were investigated at low temperatures. An easy method of estimating the strength of rock at low temperature based on the Protod'yakonov's method were examined.
From the results of microscopic observation of mineral texture in rocks after low temperature treatment, the strength characteristics of rocks at low temperatures were explained.
