Determination of Nonpropagation Distance for M74AP and M75AT-AV Mines
Abstract
As part of an Army-wide expansion and modernization program, the safe-separation distance for production of M74AP and M75AT-AV mines was studied, tested, and determined in a series of tests. The results were used to establish safety criteria for new manufacturing load-assemble-pack (LAP) facilities and also existing facilities under renovation. The program to determine the necessary minimum nonpropagation distance was drafted by ARRADCOM and was subsequently conducted in two separate phases. The exploratory phase consisted of a total of 12 separate tests, some without and some with barricades, using one donor mine and two acceptor mines. The confirmatory test phase consisted of 25 tests, 50 acceptors with the test conditions held constant. The results confirmed that zero spacing (19. cm/7.8 in. centerline distance) using a 7.6 cm (3.0 in.) thick 6061-T6 aluminum barrier between mines will sufficiently deter the possibility of propagating an explosive incident. Four tests using a 7.6 cm (3.0 in.) square barrier, the full width of the conveyor, were conducted in order to preclude the necessity of accurate mine alignment.
