Highwall and Ponding Area
OUR APPROACH TO AMLThrasher has, or is in the process of, completing eight Abandoned Mine Lands (AML) projects for the West Virginia Department of Environmental Protection (WVDEP). While the scope of the projects varies,
Thrasher has the experience and resources to apply the following design aspects:
Reclaim Refuse Piles: refuse piles were incorporated into the backfill of re-graded highwalls. These areas are then covered with soil and re-seeded.
Highwall Re‐Grading: miles of highwalls have been backfilled and re-graded utilizing plans developed by Thrasher. Balancing the amount of cut and fill and keeping the amount of disturbance to a minimum is a challenge on any AML project. Thrasher has successfully met these challenges on other projects.
Sealing of Portals: Thrasher has developed plans for dozens of wet and modified mine seals for AML projects, including bat gate mine seals.
Sink Hole Repair: shallow mine voids cause sink holes that divert natural streams underground. Thrasher evaluates each site and develops a plan to backfill the voids, thereby reestablishing the original property.
Landslide Repair: three different landslide repair projects have been completed by Thrasher. Each repair required extensive geo-technical design for soldier pile and concrete lagging and concrete segmental gravity block walls, and slip material removel for slope stabilization. These projects were in close proximity to residential areas that required special care during construction.
Drainage Design: all of the AML projects completed by Thrasher have required design of drainage structures.
These have included vegetated, grouted, riprap channels, as well as culverts and storm sewers. Drainage calculations were completed to properly size all conveyences.
Permitting: the permitting process can delay projects if they are not submitted correctly or in a timely manner. Thrasher takes pride in on our ability to quickly obtain permits for our clients. We are able to utilize our excellent relationship with the WVDEP for NPDES permits as well as our relationship with the West Virginia Division of Highways for entrance and drainage permits. We are also experienced in obtaining Army Core of Engineers permits from both the Pittsburgh and Huntington District Offices for stream bank restoration, wetland mitigation and construction, linear transportation and utility line projects, and temporary construction access and dewatering.

Landgraph Refuse Pile: This project located in Landgraff, WV involved a ± 3 acres exposed refuse site, 500 linear feet of dangerous highwall and streambank restoration of an unnamed tributary of Elkhorn Creek. The scope of work for this project included regrading the refuse site from the unnamed tributary’s stream bank and to reclaim the highwall. Then an adjoining borrow sites were used to obtain sufficient suitable material to entomb the refuse for revegetation. The project site covered a total area of 4.3 acres and reclamation included ±16,000 cubic yards of earthwork.
Stowe Landslide: This project located in Stowe WV, in Logan County, involved a 2 acre landslide caused an abandoned portal blowout. The slide mass was situated directly above a private residence at the base of a steep mountainside. Trees in the mobilized material had already caused damage to the residence’s accessory structures and fence. Based on the subsurface investigation and the slide’s proximity to the residence it was determined that the safest and most efficient way to mitigate the slide and prevent future damage to the residence was to remove slide material and excavate/regrade around the landside to a stable configuration while safely conveying surface and subsurface drainage around and through the site via deep underdrains and riprap/grouted riprap channels.
The slide material upon removal was transported to a nearby waste site, spread, dried and compacted. The project site covered a total area of 2.9 acres and reclamation included ± 6,000 cubic yards of earthwork.
Owl Creek Highwall #2: This Morgantown, WV project involved 3 main sites which includes dangerous highwalls with heights between 20 and 70 feet, AMD water impoundments on highwall benches, exposed refuse on Booths Creek stream bank, open and collapsed portals, and existing non-functioning wet mine seal. The scope of work included regrading the highwall bench and adjoining spoil piles to reclaim the highwalls, installing new or replacing the existing wet/modified mine seals for the portals producing AMD and installing bate gates in the open portals.
As well as, installing underdrains or seep collectors to eliminate ponding areas and constructing conveyances to safely transport stormwater and mine water in and around the site. Any Army Core of Engineers permit was applied for stream bank restoration/repair of Booths creek and a temporary construction access across the stream.
The project site covered a total area of 24.5 acres and reclamation included ± 113,000 cubic yards of earthwork.
