Iron Mountain Boyers

Brayman was subcontracted to provide drilling services at an underground mine facility located in Boyers, PA. Brayman’s scope of work included installation of 11-each large diameter shafts, up to 240-feet deep and 42-inch diameter, which will be used for various utilities. A combination of cluster drilling, coring, and augering were used to install the shafts in extremely tight drilling tolerances to assure the shafts broke through the mine at the precise locations. Difficult drilling conditions were encountered as the shafts extended through sands and broken rock with a very high water table.  Permanent casing was grouted into the boreholes to create a watertight seal into the mine.

In addition to the vertical shafts, 8-each horizontal holes were drilled inside of the mine. The horizontal holes were lined with steel casing and are used for passing electrical conduit throughout the mine. Brayman’s Innovative grouting procedures resulted in watertight boreholes.
