Coal-spoil and ground-water chemical data from two coal mines; Hanna Basin and Powder River basin, Wyoming

Abstract

Coal-spoil data and water-quality data for samples collected from two Wyoming coal-mining areas are presented in six tables. The Medicine Bow and Seminoe Number 1 Mines in the Hanna basin comprise one site, and the Cordero Mine in the Powder River basin is the other site. The data consist of X-ray diffraction analysis of spoil samples, analysis of the saturated paste extract of spoil samples, sulfur-forms analysis of spoil samples, analysis of water samples obtained from batch-mixing experiments, and analysis of ground-water samples collected from wells in the spoil and coal aquifers. The data were collected as part of a regional study which will evaluate methods used to predict post-mining ground-water quality of aquifers affected by the strip mining of coal in the West.

Geochemistry of batch-extract waters derived from spoil material collected at the Cordero coal mine, Powder River basin, Wyoming

“…Thus a total of 12 spoil samples were collected at the Cordero Mine. All spoil and water-quality data collected at the Cordero Mine were tabulated by Larson (1988).…”

“…Solid-phase and water-quality Wyoming, Montana, Colorado, Oklahoma, This report is the second of a [series of reports describing data collected from selected surface coal mines in Wyoming. The first report in this series (Larson, 1988) is a data report containing solid-phase and waterquality data collected from two nines.…”
