Abstract
A hollow load device for putting perforations into production, of the type comprising, on the one hand, a support consisting of a bar provided with longitudinally distributed fixing holes and, on the other hand, hollow loads, each of which comprises a body containing an explosive pan that has a hole provided with a lining, a lid tightly mounted on this body, a fixing head arranged in front of said lining and immobilized in one of said fixing holes, and diametrically opposite said head a receptacle for the detonating cord; characterized in that the outer profile of the support bar is circular, the straight section of the bar has an approximately constant thickness and, furthermore, in that the middle part of the interval that separates two adjacent fixing holes has a remarkably unitary mass area less than the unit mass of the rest of said interval.
