Which condition is commonly known as coal-miner's lung?

Coal-miner's lung is a colloquial term used to refer to anthracosis, a type of pneumoconiosis caused by the accumulation of coal dust in the lungs. This condition is characterized by the inhalation of coal dust over a prolonged period, leading to inflammation and respiratory issues. The coal particles, when inhaled, deposit in the lung tissue and may cause chronic coughing, shortness of breath, and other pulmonary complications.

Anthracosis is significant in occupational health as it highlights the importance of protective measures for workers in industries like coal mining to prevent dust inhalation and subsequent lung diseases. The other options provided do not relate to coal dust exposure or lung conditions; asbestosis is caused by asbestos exposure, anosmia refers to the loss of smell, and exsanguination relates to severe blood loss, making them unrelated to the definition of coal-miner's lung.
