Acute silicosis is rare and generally occurs only after extremely high exposures, but it causes death in most cases. Coal dust is made of carboncontaining particles, and coal miners are at risk of inhaling this dust. Coal miners may also be exposed to silicacontaining dust because coal mining may involve some drilling into silicacontaining rock.

phasis is on coal mining. The time to plan for subsidence impacts is well before mining begins, not after surface effects are noticed. Because subsidence due to underground mining may be inevitable, the relevant questions to be asked are how much, when, and where, and what abatement procedures are possible and might be necessary.
