Coal Mining and Processing The National Academies PressCoal Pillar Design Criteria for Surface Protection
Although the United States has the vast coal resource described in the previous chapter perhaps as much as 4 trillion tons the key issue for policy makers is the amount of coal that is economically recoverableThis is not a fixed quantity but depends on the geological resource the market price and the cost of mining The particular characteristics of the coal mining industry create unique Coal Pillar Design Criteria for Surface Protection D Hill1 ABSTRACT Large areas of ground are permanently supported on coal pillars both in extensive old workings and current drivages in active mining operations Continued growth of civil infrastructure is resulting in more surface development above old bord and pillar mines and an increased
