Exploratory pit and drilling at a coal-mine subsidence site (AML)

Kentucky AML wants a contractor to dig an exploratory pit and drill into the #9 coal seam to locate mine rooms and pillars.
The details:
- Owner: Kentucky Energy and Environment Cabinet, Abandoned Mine Lands (via Division of Engineering and Contract Administration)
- Reference: RFB-85-27 EEC-AML-26007AMLBAML
- Where: Muhlenberg County, Kentucky
- Closes: October 14, 2026, 9:30 a.m. Eastern
- Value: About $900,000 as listed by ConstructConnect (not stated in the state notice)
What to know before you bid:
- Scope: excavate an exploratory pit and drill 6-inch-plus holes to the #9 seam, case them through the soil, and support AML staff using a downhole camera to see how far subsidence has fractured the rock.
- Contractor handles water for flushing holes (a 400-500 gallon water tank is suggested), keeps cuttings out of yards with filter bags or a trailer, and must monitor methane and secure the hole if gas is found.
- Bonds listed: 5% bid bond or certified check, 100% performance and 100% payment bonds.
- The site visit and the question deadline were both October 2, so they have passed; planned start is mid-November 2026.
- Bids go in electronically through Kentucky’s Vendor Self Service system.
