The Taneum coal beds are also greatly disturbed, probably by the proximity of intrusive masses of lava. CLASSIFICATION AND ANALYSES OF COAL. A general, simple, and satisfactory classification for all grades of coal has not been finally decided upon by coal operators, or even by the United States Geological Survey. But a classification...
Page 89 - The lower 7 inches of the bed was not exposed. The coal is like the Roslyn coal at other mines in the vicinity. The high heating value and low ash content probably result in part from the whole thickness of the bed not being sampled. The coal was passed over bar screens. The oversize was picked and sold as lump coal. The undersize was sold as steam coal.
Page 88 - ... cars were loaded. The coal was not picked at the bunkers because it was clean enough for locomotive use. Section A (sample 551-D) was cut from a rib 1,300 feet southwest of the slope, on second level west. Section B (sample 550-D) was cut from a point 1,000 feet southwest of the slope. Notes — The coal is considered a good coking and steam coal. In 1909 it was mined either at the bottom or near the center of the bed, and was shot down with black powder. The tipple was provided with shaking...
Page 47 - Washington describes the physical characteristics of the different classes of coal as follows :f "1. Anthracite may be defined as a very hard, jet-black coal having a dense homogeneous texture, a bright luster, irregular conchoidal fracture, burning with a short blue flame, and having a fuel ratio of 10 or more. The coal from the Scranton-Wilkesbarre district in Pennsylvania is typical anthracite. "2. Semi-anthracite is below the grade of anthracite, but its limits are not well defined. In general,...

Sample 9,435 was collected on the sixth level west from slope 2, on the gangway between rooms 2 and 3. Sample 9,436 was taken from the side of the slope between the eighth and the tenth level west from shaft 4, and about 10 feet below the air course below the eighth level. A composite sample was made by mixing samples...

Sample 9,427 was taken from the barrier pillar between No. 5 mine and the old No. 1 mine, and on the gangway of the first level west of the No. 5 slope. A 3-inch parting of broken coal, clay, and pyrite occurs in the center of the bed. This was not included in the sample. 9 423 9,4'74 9 425 9 4'^fi 9 4° 7 Roof, shale...
Page 129 - ... acres, of which about 300 acres in the southeastern portion are known to contain coal. The beds, however, are thin and are probably cut and badly broken by the diabase dikes. Assuming an average dip of 60° and an aggregate thickness of 10 feet of coal, the yield would be in the neighborhood of 15,000 or 20,000 tons per acre, if the beds were continuous. At present the haul to any shipping point is prohibitive, and the coal in this field will not be available until conditions are such as to warrant...
