摘要

摘要: 针对目前煤岩冲击倾向性评价方法存在的不足，基于海明距离法基本原理，建立了煤岩冲击倾向性综合评价模型。该模型选用动态破坏时间、冲击能量指数、弹性能量指数和煤岩单轴抗压强度作为综合评价指标，应用线性内插公式构造评价对象的隶属函数，采用海明距离法获得评价对象与评价标准的相似程度，并用最小海明距离进行类别评判，从而得出评价结果。实例分析结果表明，海明距离法的评价结果与煤样的实际现场冲击倾向性一致；对处于同一冲击倾向性级别的煤样的海明距离大小进行对比，结果认为海明距离法比模糊综合评判法和熵权-理想点法具有更高的分辨率。

Abstract: In allusion to shortcomings of current evaluation methods about rock burst tendency of coal seam, a model was built for comprehensively evaluating rock burst tendency of coal seam on basis of Hamming distance theory. Dynamic failure time, impact energy index, elastic energy index and uniaxial compressive strength are selected as comprehensive evaluation indexes in the model. Membership functions of evaluation objects are structured by use of linear interpolation formula. Then similar degree between the evaluation objects and standard objects is gotten respectively by Hamming distance method. Evaluation results are gotten through using the minimum Hamming distance to evaluate classification. The analysis result of actual example shows that the evaluation results of Hamming distance method are consistent with rock burst tendency of coal seam in actually field; by contrasting Hamming distances of coal samples which are at the same burst tendency level, it is found that Hamming distance method has a higher resolution ratio than fuzzy comprehensive evaluation method and entropy-ideal point method.
