Behavior of the Working Fluid in Mechanized Support in Permafrost

Abstract

This paper summarizes the results of an investigation of mechanized support under permafrost conditions. The present paper analyzes mechanized support behavior under subzero temperatures. The influence of cooling of the working fluid on support resistance is considered, and recommendations are given for efficient operation of mechanized complexes under those conditions. The laboratory experimental data are in good agreement with the results obtained from a field study.
