Block Test Step 1 report

This document provides details of the operation of Block Test 1 Step 1, analysis of the results of Step 1, and predictive analysis and recommendations for Step 2. Step 1 consisted of a single horizontal slot cut in the rock face designed to measure uniaxial rock mass deformation at varying temperatures and pressures; and to evaluate the test set up and instrument performance. Step 2 shall consist of four slots cut in a square in the rock face, designed to measure biaxial rock mass deformation, thermal conductivity, and coefficient of thermal expansion at varying temperatures and confining pressures. 7 refs., 46 figs., 16 tabs
