The Hlubina Mine is a former coal mine located in the city of Ostrava, in the Czech Republic. It was established in the late 19th century and became one of the largest coal mines in the region, contributing significantly to the local economy and industrial development. The mine was known for its deep shafts and extensive underground workings. After decades of operation, the Hlubina Mine was closed in 1994 due to declining coal demand and environmental concerns. Today, the site is part of the Ostrava Industrial Heritage Site, which aims to preserve the history of the region's mining industry and promote tourism.
