Abstract
Prediction models were constructed for seam elevation, overburden, and sodium concentration for a lignite deposit in Ward County, North Dakota. These models were developed by mathematical-statistical techniques using surface coordinates as independent variables to permit interpolation between drill holes. The results suggest that sodium concentration in lignite may be predicted in advance of mining. This information is helpful to mine planning, specifically, in scheduling production to deliver a uniform product to existing powerplants.
