CHARLES SIMEONS M.A., in Coal: its Role in Tomorrows Technology, 1978. Publisher Summary. This chapter examines new mining opportunities. For many years, it has been the practice to line mine shafts, particularly in Britain.In many other parts of the world especially where few difficulties are expected, it has often been the custom to sink rectangular shafts either unlined or containing timbers.
Worsley Navigable Levels - Wikipedia
Coals were moved between levels using vertical shafts until 1797, when an underground canal inclined plane started in 1795 was completed. It was 453 feet (138 m) long and raised boats 106 feet 6 inches (32.46 m) . There were two locks at the upper level from which two railway tracks descended to the lower main level. Boats entered the upper locks and were seated on wagons.

Blind Shaft Development | Coal Age
Shaft development rates are a function of diameter and ground conditions. For 8- to 10.5-ft diameter shafts, which is the vast majority of what SDI does, they can complete a 500- to 800-ft shaft in four to six months. For 12-to 15-ft diameter shafts, the development rate would be between five and seven months.
