Abstract
257,495. Herdemerten, C. Feb. 12, 1926. Blasting.-Dust is removed from bore holes by means of a pipe e which is inserted in the borehole and contains a nozzle. i through which air is admitted to suck the dust from the hole and deliver it to a receptacle a. The end of the pipe is of soft material or fitted with a wire brush &c. to prevent production of sparks through impact with the wall of the bore-hole.
