    Project Description

    McCrossin Foundations was subcontracted to install drilled shafts for stacker tubes at a coal preparation plant in Bishop, WV.

    The diameters of the caissons were 36 inch, drilled to depths up to 50 feet, including a rock socket up to 20 feet. The caisson shafts were drilled primarily through coal spoil fills and weathered shale in the soil portion and hard to very hard sandstone and limestone bedrock. Due to the underlying materials and existing site conditions, most of the shafts required temporary casing during installation.

    The logistical challenges of working adjacent to an active mining operation with a heavy volume of incoming and outgoing triaxle dump trucks created both a safety and material delivery concern. The delivery of concrete and drilling tools had to be closely coordinated at the facility’s gates so as not to interfere with the coal trucks.
