Accidents in mining were common in the past. It has been estimated that the death rate for tin and copper miners in the 19th century was approximately double that in coal mining. Coal mines suffered huge losses from explosions from gas: tin mines were free from this, but accidents from blasting, falling rock and men falling in shafts – together with more unusual causes of accidents such as underground fires or flooding or lack of oxygen in the air meant that a steady high death rate was maintained.
