About this document
Drill Hole Spacing Analysis in Coal Estimation by Hardiyanto Hardiyanto is a document available to read on EtoBox.
This document discusses using drill hole spacing analysis (DHSA) to assess confidence in coal resource estimates. DHSA involves calculating the estimation variance for different block sizes using variogram models, then scaling up to the global estimation variance for the study area. Case studies show DHSA provides a quantitative way to determine resource classification distances based on variability, continuity and study area size. While geostatistics provides the most objective assessment, other factors li
