Excerpt from The Origin and Rationale of Colliery Explosions: Founded Upon an Examination of the Explosions at the Timsbury, Albion, Malago Vale, and Llanerch Collieries
This explosion also originated in an ordinary Operation Of shot firing, and under ordinary circumstances. ... The atmospheric temperature had been very low for some weeks previously, but that was a condition that may be repeated at any time during the winter seasons. It has shown that low external atmospheric temperatures have an important hygroscopic effect upon coal-dust in a mine, the ventilating currents bringing about an evaporation of moisture, and raising it to a favourable condition for the initiation of chemical actions, that end in disaster.
The Author, having examined the collieries after the explosion; now Offers the results of his investigations, in the hope that they will contribute to such an understanding of the subject of coal dust, that must command the unexceptional recognition of its dangers. The calamities that have occurred in the South Wales and South Western districts since his former work on the subject was prepared, provide full evidence that the adoption of remedies and precautions that experience now suggests, would involve an expenditure which risk to life entails as a positive duty, and that can only be described as tri¿ing compared with the value Of property destroyed, and the outlays demanded in restoring the workings and appliances of a mine to their normal state.
