2018 Wilton Phase 4, Shell Lake and Williams County Road 9 Phase 7 AML Project

This multi-site AML drilling and grouting project will continue work begun in 2015 to stabilize collapsing underground coal mines along Highway 36 near Wilton. It will also include stabilization of underground coal mines at an occupied farmstead about 14 miles north of Parshall and at businesses in an industrial subdivision at Williston. Project work includes rotary drilling, casing drilled holes and pumping cementitious grout to stabilize underground mine voids in order to prevent collapse. Testing of the grout will be covered under a separate contract. This project will be conducted between June and September 2018. The estimated cost of this project is $1.6 million. The bid opening for this project will be held April 9, 2018.

 

2018 Morton County AML Project

This 36-acre project will eliminate about 2,850 feet of dangerous final pit highwalls at abandoned surface coal mines northwest of New Salem in Morton County. These mines are characterized by steep highwalls that are about 15-40 feet high. The proposed reclamation work involves backfilling the highwalls with earthen material from adjacent spoil piles. About 120,000 cubic yards of spoil material will be moved in the reclamation process. This project will be conducted between June and September 2018. The estimated cost of this project is $300,000. The bid opening for this project will be held April 9, 2018.

 

2017-2018 Sinkhole Filling AML Project

The 2017-2018 Sinkhole Filling AML Project began in July 2017 and will continue throughout 2018 to backfill hazardous sinkholes caused by collapse of underground mines. Approximately 163 sinkholes were filled in 2017 at several sites in western North Dakota. About $96,000 remains in the contract for work in 2018.
