We shall attempt to demonstrate why this is a naive assumption. It is clearly demonstrated in Federal injury and fatality studies that underground coal mines are more hazardous than strip mines. On a production basis, comparing fatalities per million tons, strip mines are over four times safer than underground mines; and on an exposure basis, comparing fatalities per million man hours, strip mines are approximately twice as safe. This disparity in numbers is due to the higher productivity of the strip mine. In shallow deposits, like many of the Western formations, underground mining presents intolerable problems of subsidence. Under present technology, underground methods extract approximately 60 per cent of the coal, while surface methods extract over 90 per cent.
