HC Deb 18 June 1935 vol 303 cc160-1
6. Mr. TINKER

asked the Secretary for Mines whether it is his intention during the shot-firing investigation he is now making to take into consideration and examine other means of breaking down coal, such as compressed-air blasting, as this is believed to be much safer?

Mr. RUNCIMAN

I assume that the hon. Member refers to the study of simultaneous shot-firing which is at present in progress by a Sub-Committee of the Safety in Mines Research Board. This investigation is confined to the safe use of explosives, and does not extend to other means of breaking down coal. The use of such other means, however, receives constant attention and encouragement from His Majesty's inspectors, and the Mines Department is always ready to consider the merits of any new methods which may be brought to its notice.

Mr. TINKER

Is the right hon. Gentleman aware that there appeared recently in one of the scientific papers a statement about the practice in America? If I send that cutting on to the right hon. Gentleman, will he read it?

Mr. RUNCIMAN

I will see that it falls into the proper hands.

Mr. T. SMITH

Is the right hon. Gentleman aware that a great many eminent mining men are not satisfied that simultaneous shot-firing ought to be practised, and will he have further inquiries made?

Mr. RUNCIMAN

Yes, I am aware that there are differing opinions with regard to simultaneous shot-firing, and the hon. Member can take it that the matter is being closely examined now.

Mr. LUNN

May I ask whether there is a committee at the Mines Department considering alternative methods of breaking down coal, without the use of explosives?

Mr. RUNCIMAN

I think I had better be given notice of that question.

Mr. TINKER

Can the right hon. Gentleman tell us, when we are likely to know the name of the new Secretary for Mines?
