Mr. Ronnie Campbell

To ask the Secretary of State for Employment how many miners should be present in a development roadway with only one means of entry and egress under current mining regulations.

Mr. Nicholls

Section 24 of the Mines and Quarries Act 1954 prohibits the employment of more than nine persons in a place from which there are not two separate means of egress unless a notice of exemption has been given by the inspector for the district.
