Harthill and much of Central Scotland has rich deposits of coal. Digging of coal fuelled the beginnings of development in the area. Sir John Inglis of Crammond organised the first coal pits in the area at Benhar, south-west of Harthill. Nine men were initially employed and received 13 shillings per week. These miners had tied accommodation with the job and had to pay rent to the coal pit owner. If they could no longer work due to accidents or ill health, they and their family lost their accommodation. Working conditions were very poor and dangerous.
