Page 33 - Tonnage is computed from dimensions revealed in outcrops, trenches, mine workings, and drill holes. The points of observation and measurement are so closely spaced and the thickness and extent of coals are so well defined that the tonnage is judged to be accurate within 20 percent of true tonnage.
Page 33 - Indicated reserves are reserves for which tonnage is computed partly from specific measurements and partly from projection of visible data for a reasonable distance on geologic evidence. In general, the points of observation are about 1 mile apart, but they may be as much as iy2 miles apart for beds of known continuity.
Page 33 - Where no data are available other than measurements along the outcrop, but where the continuity of the outcrop is measured in miles and suggests the presence of coal at great distances in from the outcrop, a smooth line drawn roughly 1/2 mile in from the outcrop shall be used to mark the limit under cover of a block of coal that can also be classed as measured.
Page 33 - Measured coal is coal for which tonnage is computed from dimensions revealed in outcrops, trenches, mine workings, and drill holes. The points of observation and measurement are so closely spaced; and the thickness and extent of the coal are so well defined, that the computed tonnage is judged to be accurate within 20 percent or less of the true tonnage.
Page 33 - Judgment of the estimator, is larger than the actual area of drilling by as much as 1/4 mile on all sides. If, from geologic evidence, the bed is believed to have greater continuity, the area of measured coal is surrounded by a belt of indicated coal, which, according to the Judgment of the appraiser, may be as much as 1-1/2 miles wide.

Page 33 - Where there are no data available other than measurements along the outcrops, but where the continuity of the outcrop is measured in miles and suggests the presence of coal at great distances in from the outcrop, two lines drawn roughly parallel to the outcrop, one 1/2 mile in from the outcrop, and one 2 miles in from the outcrop, define a block of coal that may be classed as Indicated.

Page 33 - ... is computed from the results of detailed sampling. The sites for inspection, sampling and measurements are so closely spaced, and the geologic character is defined so well, that the size, shape and quality are well established.
