摘要

由于生产成本低，煤炭仍然是全球最重要的电力生产来源。煤炭的这一重要地位也使得煤炭资源的评估变得重要。评估中最重要的属性之一是估算矿床的热值分布。在地质统计学估计中，目前克里格及其变体得到了广泛的应用。或者，正在开发新技术，其中之一是基于径向函数的方法。在本研究中，条件径向基函数（CRBF）用于估计煤层的热值分布，同时也使用普通克里格法（OK）进行估计。将两种估算方法的结果与综合热值进行比较。结果表明，CRBF产生了比OK更高的估计范围，平均值更接近复合值。但是，与OK一样，结果仍然比合成值更平滑。

Comparison of Conditioned Radial Bases Function Approach and Kriging: Estimation of Calorific Value in a Coal Field

Due to low production cost, coal is still the most important source of electricity production worldwide. This important position of coal also makes the evaluation of coal resources important. One of the most important attributes to be assessed in this evaluation is estimating the calorific value distribution of deposit. In geostatistical estimation currently Kriging and its variants are being used widely. Alternatively new techniques are being developed and one of them is the Radial Based Functions based method. In this study, Conditioned Radial Basis Function (CRBF) is used to estimate the calorific value distribution of a coal deposit while estimations are also performed with Ordinary Kriging (OK). Results of both estimation methods are compared with respect to composite calorific values. Results show that CRBF produced a higher estimation range than OK with closer mean to composite. However, like OK, results are still smoother than the composite values.

期刊介绍： Scientific Mining Journal, which is published i n open access electronic environment and i n printed, is a periodical scientific journal of Union of Chambers of Turkish Engineers and Architects Chamber of Mining Engineers. The name of the journal was "Mining" until June 2016 and it has been changed to "Scientific Mining Journal" since September 2016 because it can be confused with popular journals with similar names and the ISSN number has been updated from 0024-9416 to 2564-7024. Scientific Mining Journal, published four times a year (March-June-September-December), aims to disseminate original scientific studies which are conducted according to the scientific norms and publication ethics at national and international scale, to scientists, mining engineers, the public; and thus to share scientific knowledge with society. The journal is in both Turkish and English. The journal covers theoretical, experimental, and applied research articles, which reflects the findings and results of an original research i n the field of mining engineering; review articles, which assess, evaluates, and interprets the findings of a comprehensive review of sufficient number of scientific articles and summarize them at present information and technology level; technical notes, which may be defined as a short article that describes a novel methodology o r technique; a case studies, which are based on the theoretical o r real professional practice and involves systematic data collection and analysis.
