2009 Hazen West Phase 2 Project
This project eliminated about 5000 feet of dangerous highwalls on a 50 acre site at an abandoned surface mine west of Hazen and northeast of Beulah. One of the highwall areas was just south of State Highway 200 between Hazen and Beulah. The reclamation was achieved by backsloping portions of highwalls and excavating material from spoil piles to backfill the remaining part of the highwalls and pits. Approximately 508,000 cubic yards of excavation was required for this project. The contractor for this project was Kern & Tabery, Inc, of Wadena, MN. Work was completed August 28, 2009, at a final cost of $597,039.
2009 Williams County Road 9 Phase 4 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 fourth year of a multi-year project in areas along Williams County Road 9 and other nearby residential areas east of Williston. Approximately 60,000 feet were drilled and 8026 cubic yards of grout were pumped into underground mine voids at this project site. The contractor for this project was Agri Industries, Inc, of Williston, ND. Work was completed May 10, 2010, at a final cost of $992,206.25. A separate contract was issued to Material Testing Services, LLC, of Minot, for testing of the grout used for this project and the final cost was $55,306.
2009 Columbus Phase 10 Project
The main objective of this project was to backfill a surface mine highwall near the access road to a farmstead at the east end of the larger Columbus AML site. About 25,000 cubic yards of spoil were moved to backfill the highwall. This project also included repair of some erosion features on reclaimed areas at the Columbus AML site. The contractor for this project was Edward H. Schwartz Construction of New England, ND. Work was completed November 6, 2009, and the final cost was $70,003.00
2009 Coal Fire Suppression Project
In January 2009, the Commission awarded a contract for coal outcrop fire suppression work at sites in McKenzie, Billings, and Slope Counties. The burning coal veins were located within the U.S. Forest Service's Little Missouri National Grasslands and on nearby privately owned property. The contractor for this project was Basaraba Excavating of Wilton, and work was completed May 12, 2009. A total of 31 coal fire sites were excavated and extinguished at a cost of $40,000.
2009 Maintenance Project
The main objective of this project was to fill dangerous sinkholes caused by underground mine collapse. Approximately 360 sinkholes were filled on 22 properties at 10 locations in western North Dakota. The contractor for this project was Basaraba Excavating of Wilton, and the final cost was $127,600.
