摘要
在大量实验室试验的基础上，总结、分析了煤岩组合模型的冲击倾向性，并与单一煤模型的冲击倾向性进行了对比分析。研究结果表明，采用煤岩组合模型测得的冲击倾向性指标均高于单一煤模型；同时考虑到实际煤岩层结构特点与覆存特性，建议采用组合模型来评价煤岩冲击倾向性。
The evaluation method of bursting liability of coal or rock with composite model is summarized and analyzed on the basis of a great deal of experiments in the laboratory. The achieved results show that indexes on bursting liability examined with composite model of coal and rock are larger as compared with single model of coal. According to the results, the composite model is advised to evaluate the bursting liability of coal or rock, considering the characters of frame and cover in point of the layer of coal and rock.
