煤层稳定性模糊模式识别评价方法

 基于模糊模式识别理论,研究了不同类型煤层稳定性的综合量化评价方法。在分析煤层稳定性关键影响因素的基础上,确定了煤层稳定性评价的特征因子,构建了不同类型煤层的模糊评价语言模式及其隶属函数,提出了煤层稳定性模糊模式识别评价方法。通过实例评价,验证了该方法的可行性,结果表明,该方法可实现对煤层稳定类型的定量划分和归属判定,可为煤层的可采性分析、开采安全性评价以及采煤方法的选择提供依据。

Evaluation of Coal Seam Stability Based on Fuzzy Pattern Recognition

The comprehensive quantitative evaluation methods for different kinds of coal seam stability based on the fuzzy pattern recognition theory are studied in this paper. The coal seam stability evaluation using the fuzzy pattern recognition method is proposed, with an analysis of the key factors affecting the coal seam stability, to determine the characteristics of the coal seam stability evaluation factors, and to build the fuzzy evaluation for different types of coal seam in language patterns and their membership functions. To verify the feasibility of the method, an example is taken for the evaluation. The results show that the method can realize the quantitative partition for the stability of the coal seam type and belonging, can provide the basis for the coal seam mineable analysis, the mining safety evaluation, and the mining method choice.
