HC Deb 18 December 1934 vol 296 c945
11. Mr. DAVID DAVIES

asked the Secretary for Mines the length in mileage of the main ventilating and haulage roadways in the coal mines of the various inspectorate districts of the country, giving the number of miles supported, respectively, by steel arching, by side-walls and camber steel arches, by timber, and unsupported, in each district?

Mr. E. BROWN

I regret that the detailed particulars asked for are not available, but a good deal of information as to the increased use of steel supports on mine roadways is given in the published Annual Reports of the Divisional Inspectors for 1933, as has been done for several years past.

Mr. LAWSON

Is the hon. Member satisfied that the roadways are always in a proper condition?

Mr. BROWN

That is much too large a question to answer as a supplementary to this detailed one.
