The estimated cost of this project is $350,000. The bid opening for this project is scheduled March 14, 2017.
2017 Wilton Phase 3 AML Project
The 2017 Wilton Phase 3 AML Project will continue to stabilize underground mine workings along Highway 36 and a farmstead near Wilton by drilling and pumping pressurized grout into mine voids. The work includes rotary drilling, casing drill holes where voids are found, pumping grout and grout testing. Work is expected to be conducted between June 5 and September 13, 2017. The estimated cost of this project is $1.4 million. The bid opening for this project is scheduled April 17, 2017.
2017 Columbus Phase 16 AML Project
The 2017 Columbus Phase 16 AML Project will eliminate about 4,500 feet of dangerous highwalls at abandoned surface mine sites located on approximately 43 acres south of the city of Columbus, ND, in Burke County. These AML sites are characterized by steep highwalls that are about 15-25 feet high. The proposed reclamation work involves backfilling the highwalls with earthen material from adjacent spoil piles. About 225,000 cubic yards of spoil material will be moved in the reclamation process. Work is expected to be conducted between June 19 and September 17, 2017. The estimated project cost is $450,000. The bid opening for this project is scheduled April 17, 2017.
2017-2018 Sinkhole Filling AML Project
The 2017-2018 Sinkhole Filling AML Project will be conducted to backfill hazardous sinkholes caused by collapse of underground mines. Some funds may be used to conduct maintenance work on reclaimed sites. If necessary, some of these funds may also be used for emergency projects. Work will be conducted as needed during the two-year contract period. The estimated project cost is $200,000. The bid opening for this project is scheduled April 17, 2017.
