摘要
Analytial samples collected in solid mineral resources geological explorations must exhibit the represent activeness of material fabrics of rocks and ores.Representativeness of samplings is decided by the uniformities of material components,and section specifications and layouts of samples.The more uniform is the distribution of material components of rocks and ores,and the bigger is the size of sections of sample cells and the larger is the volume of samples,the better is the representativeness of samplings.Some disadvantageous factors,such as too little size of sections of sample cells,irrational layout and exceeding limit of sample weight error,will affect the reliability of geological prospecting work quality,technical and economic evaluation of deposits.Based on the uniformities of material components of rocks and ores,and the degrees of explorations, this paper makes a comprehensive discussion on the selection of trench samplings in solid mineral resources geological explorations,which has an important guiding significance for planning and implementation of working schemes of mineral resources geological explorations.
