Most research on Neandertal teeth has focused on shovel shaped incisors and/or taurodont molars. In the past 15 years there has been a renewed interested in Neandertal dental morphology, especially with regard to how they compare to recent and fossil modern humans. However, no complete description of Neandertal dental morphology has been published since the mid-1950s. Many more Neandertals and ...

The article describes the main types of technological schemes for working out flooded strata sand deposits using hydraulic shovel excavators. analysis scientific and technical literature describing experience excavators in open-pit mining, including pits extraction construction sand, has been carried out. proposed scheme is that development reserves without preliminary water reduction by a exca...

Abstract The current cultivated land quality (CLQ) evaluation method fails to consider the determination of soil nutrients, resulting in low efficiency nutrient message extraction. In an effort effectively solve above problems, combined with spatial variation nutrients (SVSN) at field scale, a CLQ is proposed. were determined according analysis, and color was standardized. characteristic bands ...

In-pit crushing and conveying (IPCC) systems have drawn attention to the modern mining industry due numerous benefits than conventional truck-and-shovel systems. However, implementation of IPCC system can reduce flexibility introduce additional sequence requirements. This paper investigates long-term production scheduling crusher relocation plan open-pit mines using a semi-mobile high-angle con...
