Investigation of a subbituminous coal deposit suitable for opencut mining, Beluga River Coalfield, Alaska

Technical Report ·
OSTI ID:5389508
Report describes investigation of a geologically favorable area in the Beluga River coalfield to determine minable coal reserves to meet the projected thermal power needs of the Anchorage area. Diamond core drilling indicated reserves of more than 20 million tons of coal that could be mined by opencut methods. A coal sample, with 4 volume-percent of clay partings eliminated, contained 24.4 percent moisture and 16.8 percent ash and had a calorific value of 7162 Btu per pound. Studies indicated that mechanical cleaning would be of doubtful value.
