RFB-187-26 EEC-AML-25061AMLBAML

Estimated Length of Project:
(Substantial Completion) + 180 Calendar Days (Final Completion)

The project will begin as an exploratory geotechnical investigation and dig two exploratory pits and drill 4 exploratory borings. The pits will be dug at the two
surface expressions of subsidence to gather additional information necessary to determine if the subsidence is related to historic mining in the Hawesville Coal Seam. Historical documents suggest this coal seam was mined for steam coal for river boats on the adjacent Ohio River. Four exploratory borings will also be advanced in the general area to determine if mine voids exist and if there has been any collapse in the mine voids if they do exist. Percussion drilling and air-hammer drills are not allowed on this project. Methane monitoring is the responsibility of the contractor, and if methane is encountered, the contractor must immediately implement a plan to secure the area. After the initial exploratory work, AML staff will determine if the subsidence is mine related or if it could be related to collapsing buried domestic tanks or related to karst geologic conditions that may exist at the site.
If it is determined that AML eligible mining is associated with the subsidence events, then soil and rock drilling will be required as generally shown in the plans with location adjustments made as necessary by AML staff. AML employees will utilize a downhole camera to verify current conditions in the mine and to determine the extents of the rock and shale fracturing from the mine subsidence. Approximately 400 gallons of water will be required to flush each hole after drilling is complete to improve the performance of the downhole camera. The contractor should utilize a 400 – 500 gallon “water buffalo” to ensure adequate water is available and can be used to flush the hole in 10-15 minutes. AML staff will make any
necessary adjustments to the proposed hole locations for grouting the coal seam. Six-inch plus diameter holes will be drilled to the Hawesville coal seam in the specified order. The hole will be cased through the soil horizon into solid competent rock with 6-inch diameter PVC pipe. Two grout mixes have been specified. A stiffer grout mix will be used to create pillars around the residences and a more flowable grout mix will used as determined by AML staff. Methods of placement of grout will be evaluated for effectiveness but will require a concrete/grout pump to access areas near the houses or where concrete trucks would damage the yards.
