1The following abbreviations apply to sample type: SH-shale; SS-sandstone; CO-coal; and
2CL-clay.
Geologic strata includes: OVBWA-overburden materiel above Wedge coal seam;
IHBWA-in[erburden parting materiel between the upper and lower Wedge coal seam sections;
WADGE-Wedge coal seam; UNBWA-underburden material below Wedge coal seam in the Wedge coal
recovery area; LENNO%-Lennox coal seem; OVBWC-overburden material above the Wolf Creek
coal seam in the Wolf Creek coat recovery area; WC-Wolf Creek coal seam; and
3UNBWC-underburden material below Wolf Creek coal seam.
When the total percentages are equal to or greater than 20 percent for a particular site,
the strata percentage values contain an asterick and a discussion is included in the
Mixing and Mitf gation of Unsuitable Material sectf on. No percentage figures are included
for the underburden or the no-coal sites since an incomplete section was sampled. The
4N/A (not eppLicable) is used for coal seams that will be extracted or avoided.
Mitigative measures include: AM-amelioration; AV-avo idance; E%-extracted by mining;
LE-laboratory error; M-mixing; SC-sample contamination by drilling grease; and
SH-selective handling.
