ABSTRACT The following work of investigation refers to different tests of soils in laboratory and field they were realized with the aim to look for the utilization of the sediment generated in the Acid Water Treatment Plant of Minner La Zanja mixed with slimy sand and clay to achieve useful soil of low permeability in the closing of the Warehouse of Inadequate Material. The study has focused in the technical specifications given by Knight Piésold, who indicates values for granulometric spindle, consistency limits minimum of 15, percentage of compaction of 95 %, range of dampness after the compaction-2 to +3 and coefficient of permeability not major to 1x10-6 cm/s, as determinant factors to obtain a soil of low permeability. The investigation initiated in laboratory, testing every type of soil (sediment, slimy sand and clay) in an individual way then they were mixed to different proportions, in agreement to the results, the following proportion was obtained: 20 % of sediment, 40 % of slimy sand, 40 % of clay. The mixture obtained in laboratory was removed to field and it was extended in an area of 15 x 10 m2 in the Warehouse of Inadequate Material (DMI) with a compaction to 95 % of the maximum dry density; to a thickness of 200 mm, in which it was possible to determine the Density of Field and Permeability of the soil. The laboratory test programs and field were realized according to procedures of the international procedure ASTM (American Society for Testing Materials). The obtained results are: index of plasticity (IP) 23, determined according to ASTM D4318; coefficient of permeability 7.8×10-6 cm/s, determined according to Drainage manual USBR; compaction to 97.5 % of the maximum dry density, determined according to ASTM D698; ideal content of dampness in laboratory was 32.1 %, in field 34.05 % being inside the range-2 to +3 % indicated in the technical specifications. Hereby we determine the viability of our hypothesis that looks for the utilization of the sediment from the Acid Water Treatment Plant mixed with slimy sand and clay to obtain a useful soil of low permeability in the closing mine.
