Characterization of the spatial variability of mill tailings hydraulic properties: a statistical and geostatistical analysis.
MS Thesis New Mexico Inst Min and Technol Socorro New Mexico, 1987 Mar; :1-238
This paper describes a study of an abandoned lead-zinc tailings impoundment in west-central New Mexico. The method of tailings deposition at this site was an upstreaming peripheral discharge system. Generally, this type of system produces a sedimentary structure that coarsens vertically upward and fines laterally away from the emitters. The use of galvanized thin wall samples (shelby tubes) recovered with the aid of a drilling rig was the most advantageous method of sampling. The samples were obtained from a cross section made up of horizontal transects at two given depths and six vertical transects. Hydraulic parameters tested included saturated hydraulic conductivity, porosity, moisture content- pressure head relationships, and particle size, and in situ moisture content was measured with a neutron-probe moisture meter.
