III Illlllllllllllll ~ ~S ~ ~ '~ ~~" '~`~~ <br />~z~~~ <br />vicinity of the Golden Eagle Mine. To BRI's knowledge, no <br />surface mines are planned in the near future which would <br />conflict with the operation of the Golden Eagle Mine. <br />2.05.6(6) Subsidence Survev, Subsidence Monitoring, sad <br />Subsidence Control Plaa <br />This section discusses the effects that mining and <br />subsidence induced by mining may have on the permit and <br />adjacent area. The Mine Plan as shown on Map 4, shows the <br />area of anticipated mining and the projected timing sequence <br />to be followed during this five year permit term. <br />Permit revisions for coal exploration within the permit area <br />are pending before the Division. It is anticipated that the <br />results of exploration and other factors will result in mine <br />plan changes, either within this permit term, or during <br />subsequent terms. The timing sequence and location of <br />underground mining operations may be changed to reflect <br />changes in the mine plan, in coal market conditions, and in <br />coal quality requirements. <br />(a) The Structure Inventory Map, Map-16, provides a brief <br />description of all structures known to be located within and <br />adjacent to the areas to be affected by mining under the <br />currently proposed mine plan. The following types of <br />structures have been identified: <br />1) Buildings. All buildings lie outside of the area <br />projected to be affected by mining under the currently <br />Proposed Mine Plan. <br />2). Powerlines. The powerline located over NW#1 & #2 <br />Longwall Panels has already been undermined. Visual <br />monitoring and examination of the poles during and after <br />mining did not indicate any structural damage, nor <br />diminution of value. <br />3). Buried telephone line. A buried line lies under a <br />portion of the NW#1 LW Panel mined in 1991. This line was <br />installed after mining. There has been no loss of service <br />due to line failure, thus there is no indication of <br />structural damage nor diminution of value. <br />4). Waterlines. A waterline to provide water to the Rancho <br />Escondito Ranchettes from the Trinidad City water main was <br />undermined and the area subsided by the NW#1 Longwall Panel <br />in 1991. There has been no indication of damage to the <br />water line from 1991 to the present. (Reportedly, the water <br />line was not in service in 1991, nor had it been returned <br />to service at the time of this revision. Reference further <br />discussion under Subsidence Control Plans.) <br />2.05-48 <br />(Revised 1-17-94) <br />I' W I ~~ <br />
