Clum Mine Maintenance Project

A previous mine safeguarding project took place in this area in 1992. The AML Program attempted to preserve a headframe and associated wooden cribbing over a mine shaft and maintain airflow for bat habitat at the same time. A three-foot diameter culvert was installed and held in place with polyurethane foam. In the subsequent years, the headframe disappeared and soil material started subsiding into the mine void on the outside of the wooden cribbing. Eventually, airflow was blocked by the subsiding material and a 20-ft shaft remained. AML Program decided to safeguard it once again.

The project involved the following work:

  • Removing material and backfilling mine feature
  • Site Grading and Extreme Roughening
  • Seeding of all areas disturbed by construction.
