A method for coiling a signal transmission line to facilitate deployment of the line is practiced by winding the line in a plurality of sequential spirals about central axes and disposing the spirals in mutual coaxial relation so that adjacent spirals are wound in opposing directions about their respective axes sensed moving along the line from the innermost winding of each spiral to the outermost winding. A transition portion extends from the end of one spiral to the beginning of the next. When there are three or more spirals, the transition portions may be staggered about the common central axis of the spirals. A separator sheet (56) may be placed between the spirals. The signal transmission line may be a line charge (14), e.g., detonating cord, that constitutes part of a mine-clearing apparatus (10). The apparatus (10) may also have deployment structures (16, 30, 34, 22) for deploying the line charge (14) onto a mine field; and initiation structures (24, 26, 34) for initiating the line charge (14). |
