2008 Completed Projects Archive
2008 Columbus Phase 9 AML Project
The main objective of this project was to backfill highwalls and spoil grading on about 75 acres of mined land located southwest of Columbus in Burke County. Approximately 820,000 cubic yards of spoil material were moved during reclamation. Work at the Columbus Phase 9 AML site started in June 2008, and except for seeding and cleanup, was completed by November 2008. The Commission entered into a separate contract in early 2008 for tree and shrub planting on the reclaimed areas at the Columbus site in the spring of 2008. In addition, another contract was signed in late 2008 for tree and shrub planting on the reclaimed areas at this site in the spring of 2009. The contracted work was completed for a total cost of $1,197,998.47.
2008 Williams County Road 9 Phase 3 Project
The objectives of this project were to drill holes to locate underground mined workings and to pump a cementitious grout through these holes to fill the mine voids and reduce the likelihood of collapse. This was the third year of a multi-year project in areas along Williams County Road 9 and nearby residential areas east of Williston. A total of 49,951 feet were drilled and 3,880 cubic yards of grout were injected into underground mined workings and the work was conducted between June and December of 2008. Some cleanup and road repairs remain to be completed in the spring of 2009. A separate contract was issued for field and laboratory testing of the grout used for this project.
2008 Maintenance Projects
Four contracts were awarded in 2008 for sinkhole filling at numerous abandoned underground coal mines in the western portion of the state. Three of these projects were completed in the summer and fall of 2008, while work on the fourth project was postponed until the spring of 2009. The three projects completed in the fall of 2008 totaled $77,075.00.
Completion of a Project Started in 2007
In October 2007, the Commission entered into a contract for exploratory drilling at abandoned underground mines in Mercer and McLean Counties. The abandoned underground mine site in Mercer County was located in southeast Beulah and the other was located along State Highway 200 east of Underwood in McLean County. The work in McLean County was completed in November 2007 and no underground mine voids were detected at that site. The work in Beulah began later in 2007, but was not completed until the spring of 2008. The contractor drilled d204 holes totaling 16,430 feet. The contracted work was completed for $75,490.00.
