FIELD ACTIVITIES AT THE COAL BASIN MINE, 1995 <br /> CONFIDENTIAL <br /> This report discusses the field activities undertaken by the <br /> Division of Minerals and Geology at Coal Basin during 1995. The <br /> report discusses activities and observations related to spring run <br /> off, site maintenance, progress of reclamation construction during <br /> 1995 and field work accomplished in support of future reclamation <br /> bids. The rationale for field directed changes to this years work <br /> are included. A discussion of areas of concern and recommendations <br /> for future work is included at the end of the report. <br /> SUMMARY <br /> What had been anticipated as routine spring maintenance of the road <br /> drainage system developed into a , major effort to maintain the <br /> integrity of the Dutch Creek Flume, which was in danger of <br /> overtopping due to obstructions created by rock deposition within <br /> the flume. The spring maintenance project also evolved into a <br /> project to remove snow from two haul roads in order to access the <br /> mine entries in time to hold pre-bid meetings. If the pre-bid <br /> meetings were held later in the spring, it is possible that the <br /> projects may not have been completed this year. <br /> Site measurements were made for reclamation of Mines 1 and 2 , and <br /> a contract was awarded in October. This project will begin in mid- <br /> June, 1996. <br /> Backfilling, grading, drainage control and revegetation efforts <br /> were completed at Mines 3 and 4 during 1995. Reclamation of the <br /> Sutey and Old Refuse Piles was also completed this year. <br /> Approximately 49 acres were revegetated in 1995. <br /> Four revegetation test plots and one erosion control experiment <br /> were initiated on the outslope of Mine 4. <br /> Site maintenance was accomplished during the early fall of this <br /> year. Road ditches were cleared of debris where necessary, and <br /> culvert entries were cleared of accumulated sediment. The nine <br /> feet diameter steel culvert was removed from the Dutch Creek Flume, <br /> and the eroded portions of the concrete base of the flume were <br /> repaired. <br /> Field work necessary to produce bid documents for reclamation of <br /> the roads leading to the 3 , 4, and 5 Mines was accomplished.
