Abstract : The Joint ROK U.S. R&D Program for New Underground Ammunition Storage Technologies was established in 1991 as a 5-year cooperative research effort between the United States (U.S.) and the Republic of Korea (ROK). The purpose of the program is to develop new design concepts for underground ammunition storage facilities that will significantly reduce the hazard distances and areas presently proscribed for ammunition storage sites by U.S. Department of Defence (DoD) and ROK Ministry of National Defense (MND) safety regulations. An extensive series of small-scale experiments and computer model calculations was conducted in the U.S. and Korea under the joint R&D program to evaluate the effects of various underground magazine design features on the external blast effects. Based on the results of these efforts, each country conducted a series of intermediate-scale tests, using tunnels and storage chambers excavated in rock, to further study the most promising design features. The U.S. intermediate-scale tests were conducted at 1/3-scale in an inactive mine complex, named the Linchburg Mine, located near Magdalena, NM. This report describes investigations performed by TerraTek, Inc. to characterize the material properties of the rock medium in the test area of the Linchburg Mine. 1.2 SCOPE AND SUMMARY OF INVESTIGATIONS. Laboratory tests were conducted on predominantly limestone core samples from the Linchburg mine. The core samples were retrieved from horizontal drill holes located in test chambers and drifts. Tests were conducted on thirteen core intervals to characterize the material. This included lithologic descriptions, physical property measurements, ultrasonic velocity measurements, uniaxial compression tests, and uniaxial strain tests.
