A jigging machine, particularly a movable sieve jigging machine, for the preseparation of deads from valuable material comprises an oscillatory jig bed in the housing filled with separating fluid and comprises deads and valuable material discharge devices located therein, as well as an oscillatory drive for the jig bed. The jigging machine is suitable for underground mining operations in that the outer dimensions of the jigging machine, with respect to the height and width theeof, are designed smaller than the tunnel cross-section of an underground mining operation. A relatively low structure is achieved by designing the housing as a flat trough towards a deads discharge end with the deads discharge being provided as a rising conveyor parallel to the bottom of the trough. Advantageously it is achieved that the quantity of deads to be conveyed is reduced and a considerable saving is provided in terms of energy and expense.
