asked the Secretary for Mines whether he is now prepared to include in the regulations stemming plugs as a permitted method to be used in shotfiring?
§ Secretary for Mines (Mr. Geoffrey Lloyd)
The use of stemming plugs is permissible under the existing shot-firing rules, as long as the plugs and any attachment thereto are non-inflammable.
Is the hon. Gentleman aware that this is not actually in the regulations, and that there is anxiety that it should be included among the permitted methods?
