摘要
运用相似材料模型试验，提出了顶煤冒放的桥拱式、半拱式和柱式３种结构特征；分析了影响顶煤冒放性的主要因素；运用数值方法得出了各因素的影响规律、主次排序和权重；基于模糊数学理论，提出了预测顶煤冒放性的分类方案．并运用全国２９个主采煤层的分类结果验证了分类方案的正确性和实用性．
Based on the similar simulation model experiment, the three forms of the bridge arch, semi_arch and pillar on the top coal caving and drawing characteristics are put forward. The main factors to affect the top coal caving and drawing characteristics are analyzed. By numerical method, the influence laws of the factors and their primary and secondary as well as weight are obtained. On the basis of fuzzy theory, the classification program to forecast the top coal caving and drawing characteristics is provided. The correctness and practicability of the classificated results have been confirmed by the 29 main coal seams in China.
