§ 201.1

Conditions necessary for classification of land as coal land.

Land shall be classified as coal land if it contains coal having:

(a) Minimum heat value. A heat value of not less than 8,000 B. t. u. on an air-dried, unwashed or washed, unweathered mine sample.

(b) Minimum thickness. A thickness of or equivalent to 14 inches for coals having a heat value of 12,000 B. t. u. or more, increasing 1 inch for a decrease from 12,000 to 11,000 B. t. u., 1 inch for a decrease from 11,000 to 10,500 B. t. u., 1 inch for each decrease of 250 B. t. u. from 10,500 to 10,000, and 1 inch for each decrease of 100 B. t. u. below 10,000.

(c) Depth below surface varying with thickness and heat value; exceptions. A depth below the surface for a bed of coal 6 feet or more thick of not more than 100

feet for each 300 B. t. u. or major fraction thereof, and for a bed of minimum thickness for that coal a depth of not more than 500 feet, and for beds of any thickness between the minimum and 6 feet a depth directly proportional to that thickness within these limits, provided that, if the coal lies below the depth limit but within a horizontal distance from the surface not exceeding 10 times the depth limit, or if its horizontal distance from the foot of a possible shaft (not deeper than the depth limit) plus 7.5 times the depth of such shaft does not exceed 10 times the depth limit, the land shall be classified as coal land: Provided further, That the depth limit shall be computed for each individual bed, except that where two or more beds occur in such relations that they may be mined from the same opening the depth limit may be determined on the group as a unit, being fixed at the center of weight of the group, no coal that is below the depth limit thus determined to be considered.

§ 201.2 Classification by quarter-quarter sections or surveyed lots.

Classification shall be made by quarterquarter sections or surveyed lots.1

§ 201.3 Review of classification.

Review of classification may be had only on application therefor to the Secretary, accompanied by a clear and specific statement of conditions not existing or not known to exist at the time of examination.

On and after July 1, 1944, the administration of the regulations in this part, save and except for those provisions dealing with inspections for the safety and welfare of miners engaged in mining operations on land covered by coal leases, licenses and permits shall be vested in the Geological Survey, Department of the Interior.

(b) Effective July 1, 1944, the function of making inspections for the safety and welfare of miners under the regulations in this part providing for such inspections shall be vested in the Bureau of Mines, Department of the Interior.

(c) The enforcement of the regulations in this part will remain the function of the Geological Survey.

[9 F. R. 7746, June 12, 1944]

The following expressions wherever used in the regulations in this part shall have the meaning here indicated:
