Ocean Mine No. 1 Complex, Powerhouse & Ventilation Fan, Midland, Allegany County, MD

Significance: The Ocean Mine Number One Ventilation Fan and Powerhouse are among the few structures remaining from what was once the Consolidation Coal Company's Ocean Mine Number One complex. Together they represent important improvements in coal mine safety and efficiency. They are also significant as reflections of the last wave of capital improvements in tunnel mining before the industry shift to surface, pit, and strip coal mining. The belt-driven Aerodyne-type fan sat above a brick-lined vertical mine entrance where it could force air into the mines below. The powerhouse was erected as a shop for the manufacture, repair, and transportation of ore carts for use in the mine.

Survey number: HAER MD-73
