摘要：In blasting rock, a drill hole ( 12 ) is charged with spaced, composite layers ( 20 ),( 30, 40 ) at different levels between an open mouth ( 14 ) and a blind bottom ( 16 ). Eachcomposite layer is supported on a plug ( 22, 32, 42 ). Flowable plunger material ( 24, 34,44 ), e.g. drill cuttings, is supported on the respective plug followed by blast material (26, 36, 46 ), topped by a further layer of plunger material ( 28, 38, 48 ). The plungermaterial ( 48 ) at the top, is in the form of tamping. The composite layers are spacedrespectively from one another and optionally, from the bottom ( 16 ). Initiators ( 27, 37,47 ) can be actuated by means of a controller to initiate the blasting material to displacethe layers of plunger material at speed to collide, e.g. with the bottom and with oneanother to concentrate enemy at the collision sites.
