摘要
煤层稳定性分类的正确与否,不仅关系到勘探工程布设的合理性及勘探效果,同时,还关系到矿井建设中工作面的布置及开采方式的选择。本文分析了影响煤层稳定性的主要因素,并对现有煤层稳定性定量评价的数学方法进行分析,指出了它们的优缺点。提出了趋势面分析法和数理统计法相结合的数学模型——趋势变异法对煤层稳定性进行定量评价的新思路。该思路不仅考虑了不同煤层厚度变化的离散程度,而且还考虑了煤厚点的空间分布特征和变化规律。
The coal bed stability classification is correct or not,which relates to directly the geological exploration type of coal resources,the exploration effect,the mining face layout and the mining method choice in the mine construction.Based on the analysis of the main factors which affect the coal bed stability,the analysis of the mathematical methods as well as the advantage and disadvantage of mathematical methods applied to quantitative evaluation of the coal bed stability,this thesis has advanced a new idea that is a combination method of the trend surface analysis and the mathematical statistics（that is,the trend and variation method） to the quantitative evaluation of coal bed stability.This idea considers the discrete degree of the different coal bed thickness change and the spatial distribution and relativity of these coal thickness points value.
