<' .? <br /> y f <br /> Coal Basin Mines — 1994 Reclamation Schedule and <br /> Cost Estimate <br /> 1 ) Introduction <br /> This schedule and cost estimate are preliminary in nature and are <br /> meant to give a general plan for the 1994 reclamation work . <br /> In 1993, Mine #5 was reclaimed and salvage operations had almost <br /> completely removed buildings at Mines #3 and #4 . With removal of <br /> the conveyor tubes and some minor items at the #4 Mine, both sites <br /> will be ready for backfilling and grading. <br /> The enclosed chart, titled Coal Basin Mines Reclamation Schedule - <br /> 1994 Construction Season, explains what activities will be <br /> undertaken , when they will be undertaken and what complement of <br /> labor and equipment are needed. As is seen from the column at the <br /> far left, the complement of labor and equipment is nearly identical <br /> to that which was used in the last part of the 1993 season, with <br /> the exception of a Cat 631D scraper used to place topsoil at the <br /> Sutey Pile. <br /> It is assumed that weather will not allow work to commence at the <br /> lower elevations until June 1 . Also , it is assumed that weather <br /> will not allow work past October 19 . This is conservative, since <br /> weather conditions in most years do allow work past this date. <br /> The Cat D8N is the single most important item of equipment in the <br /> schedule and is needed virtually throughout the entire work season . <br /> Road Reclamation <br /> Although the exact details of the road reclamation are not yet <br /> determined , all roads will likely be reclaimed by one of two <br /> methods. One method involves following the existing reclamation <br /> plan in places where it is not desirable to direct water over the <br /> road outslopes. Basically, this plan involves keeping a ditch on <br /> the inside edge of the road although the road and ditch may be <br /> moved out from the toe of the cut slope. In areas where it appears <br /> that the outs 1 ope is sufficiently stable to handle flow from above, <br /> a minor amount of grading will be done to establish a grade of less <br /> than 4% f rom the cut s 1 ope above to the outs i de edge.
