《体积模型法计算煤层碳、灰、水含量问题的讨论》一文,着重分析了三元体积模型法用于密度和声速两种物理量时对测量精度的要求问题。总的来说,三元体积模型法对物理量的测量精度要求高,而影响仪器测量精度的因素又较多,要使解释结果达到实用价值,当前是困难的。另外,使用两种参数方法对煤层进行测 “Volumetric Model Method for Calculating Carbon, Ash, Water Content in Coal Seam”, a paper focuses on the analysis of the requirements for the measurement accuracy when the ternary volumetric model is applied to two physical quantities, density and sonic velocity. In general, the ternary volumetric model requires high precision in measuring physical quantities, and there are many factors that affect the measurement accuracy of the instruments. To make the interpretation of the results practical, it is currently difficult. In addition, two parameters are used to measure the coal seam
