Mr. Whiteleyasked the Secretary for Mines whether he can state the number of mines in each district where shot-firing takes place and the types of safety stemming plugs that are at present in use?
§ Captain CrookshankThe following table shows the number of mines in each inspection division in which any explosive was used during the year 1937. There were 1,751 such mines out of a total of 2,120 at work. I am informed that the Voortman stemming plug is used at certain mines, but I do not know of any other type of patent plug in use.

Mr. Whiteleyasked the Secretary for Mines whether he will now consider the Voortman safety stemming plug as a measure to be adopted in all cases of shot-firing?
§ Captain CrookshankThe advantages of this plug have been considered, but as at present advised I am not prepared to make its use compulsory.
