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。
Based on the theory of fuzzy pattern recognition, the comprehensive quantitative evaluation method for the stability of different types of coal seams is studied. Based on the analysis of the key factors affecting the stability of the coal seam, the characteristic factors of the coal seam stability assessment were determined. The fuzzy evaluation language model and its membership functions of different types of coal seams were constructed. The fuzzy pattern recognition evaluation method of coal seam stability was proposed. The feasibility of this method is verified by example evaluation. The results show that this method can realize the quantitative classification and attribution judgment of the stable type of coal seam, which can be provided for the analysis of coal mining admissibility, mining safety evaluation and the selection of coal mining methods in accordance with.
