Bucky, this is the shaft sinking regulations, you were looking in the wrong place.
“Pretty sure that they need two shafts before they can start mining, mines (safety of exit) regulations 1988).”
How can you have two means of escape when you sink a shaft.
The Mines Regulations 2014
Shafts, outlets and winding
Regulation 36 Shaft construction and modification
The mine operator must ensure that, so far as is reasonably practicable, the construction and modification of every shaft is planned, designed and carried out so as to be safe and without the risk of injury to any person.
188 In the planning, design and construction of a new shaft, or staple shaft, or the modification of an existing shaft the nature of the strata through which the shaft will be sunk, and the eventual duty of the shaft, should be taken into account. The lining of the shaft should be suitable to safely withstand the forces applied to it, including hydrostatic from water-bearing strata or from weak or semi-fluid strata.
189 The mine operator should identify the hazards to workers and others during the shaft construction or modification operations, eg falls from height, ground movement, falling objects, inrush and outburst, and the lack of a second means of exit. Arrangements which allow for a safe system of work should be developed and implemented, including the provision of a safe means of exit for all people from any part of the shaft to a safe place.
190 Shaft construction operations will involve the use of specialised equipment. The mine operator should make sure that such equipment is specified, designed, installed and operated safely.
