There are not many accidents in the shafts considering how deep they are and the speed at which the cages travel up and down. This shows how well the equipment is operated and looked after and the value of the laws introduced to limit the number of miners being pulled up at a time.

Deaths caused by falls of coal and stone are few, considering the depth of the mines and the use of wooden props to support the roof whilst the coal is removed. The mine owners must be praised for making sure that there is specific person responsible for getting the wood and putting up the props, instead of leaving it to the miners, as in other parts of the country.
