| titleOfInvention | Device for explosion-reactive drilling |
| abstract | FIELD: mining and construction, driving of workings in form of holes in hard rocks. SUBSTANCE: device for explosion-reactive drilling has body, casette with deflecting hollows accommodating explosive charge and initiating unit. To enhance efficiency in operation, the device is furnished with additional casettes installed along the longitudinal axis of the device and fastened to one another and to the main casette. Deflecting hollows are made in form of blind holes or annular recesses located in lower part of each casette and opened towards hole face, and in the upper part of each casette, and opened in direction of hole mouth or its walls. Longitudinal axes of deflecting hollows are directed at angle to device longitudinal axis. Initiating unit is multichannel with possibility of alternate initiation of explosive charge in each casette. EFFECT: higher efficiency. 9 cl, 4 dwg |
