Spatial sampling optimization is an important issue for both geo-chemists and geo-statisticians. Many spatial sampling optimization methods have been previously developed. In this paper, we present a spatial simulated annealing method is presented using hyperspectral data.This sampling method was applied in a project concerning environment assessment of the Dexing Copper Mine. Mine waste contai...

Natural analogues allow scientists to investigate biogeochemical processes relevant to radioactive waste disposal that occur on time scales longer than those that may be studied by time-limited laboratory experiments. The Palmottu U-Th deposit in Finland and the Bangombé natural nuclear reactor in Gabon involve the study of natural uranium, and are both considered natural analogues for subsurfa...

Abstract Blasting performance is influenced by mechanical and structural properties of the rock, on one side, blast design parameters other. This paper describes a new methodology to assess rock mass quality from drill-monitoring data guide blasting in open pit operations. Principal component analysis has been used combine measurement while drilling (MWD) information two drill rigs; corrections...

A primary objective of the Engineered Barrier Design Test (EBDT) at the Yucca Mountain Exploratory Shaft Test Site is to examine how the variably saturated, fractured rock mass surrounding the waste package will respond hydrothermally to heating, cooling, and infiltration. The EBDT will include several partialand/or full-scale electrical heaters to simulate the thermal load generated by the was...
