OFR-70-75 Barodynamic Analysis Of Large Mine Models And Preparation Of Undisturbed Rock Specimens ? Introduction

The Bureau of Mines Contract No. H0101706 with Virginia Polytechnic Institute and State University was a part of a broad-scale investigation directed toward applied problems in mine safety and particularly toward preventing accidents and fatalities resulting from falls of roof and ribs in coal mines. Under the auspices of the Chemical Stabilization Program, Bureau of Mines, Spokane Mining Research Center, Spokane, Washington, the broad objective of the Contract was to conduct research for the purpose of studying the behavior of large engineering structures. Contract No. H0101706 consisted of two related but distinct tasks. TASK I was to make "Barodynamic Analysis of Large Mine Models," and TASK II was "Preparation of Undisturbed Rock Specimens.?
