the B coal elevation (approximately 50 feet) and at the D coal <br />elevation (approximately 25 feet). <br />• The area directly above the augered endwall will be a coal and <br />overburden haul road and dragline walkroad, so ground stability <br />must be maintained in this area. It will be several years before <br />the spoil from the pit dumps completely fills in the endwall area <br />that will be augered. Backfilling the endwall will occur during <br />the normal sequence of backfilling presently occurring in the pit. <br />In terms of maximizing resource recovery while providing for the <br />safety of the workers, Auger Area #1 was a success. The success of <br />this first auger has improved the feasibility of future auger <br />mining at other Colowyo pit area locations.. <br />In 1996, Colowyo had an opportunity to implement auger mining in <br />the West Pit, known as Auger Area # 2. The auger plan (TR-36) was <br />filed with the Division and subsequently approved. Due to <br />increased coal sales in 1996, the auger project was never conducted <br />and coal production was obtained by the conventional mining <br />methods. <br />Refer to Section 4.23 Auger Mining for detail regarding the <br />performance standards applicable to auger mining. <br /> <br />2.05-38b <br />,.-;r •: <<_ ~,:: -.p?roved 4 ~ z z /4 '~` <br /> <br />
