HC Deb 08 March 1911 vol 22 c1212
Mr. JOHN WARD

asked whether the Mines Regulations Acts and the Mines (Eight Hours) Act applied to the operation of coal pit sinking?

Mr. CHURCHILL

The answer is in the affirmative. Section 75 of the Coal Mines Regulation Act, 1887, defines "mine" as including "every shaft in the course of being sunk."
