| 摘 要： | 为了研究电磁辐射技术在三软煤层中预测煤与瓦斯突出的可行性,以煤岩流变破坏电磁辐射试验研究为基础,采用KBD5监测仪在所选矿井进行了动态跟踪监测,然后将测试结果与常规预测指标对比分析.煤岩蠕变破坏试验表明,接近煤岩破坏阶段,电磁辐射信号明显增强.从三软煤层煤与瓦斯突出现场测试结果得出,电磁辐射强度与所选矿井采用的钻孔瓦斯涌出初速度q和R值指标具有较好的正相关对应关系,即电磁辐射指标和煤与瓦斯突出危险性常规预测指标之间具有较好的对应关系.可以应用电磁辐射技术预测三软煤层采掘工作面的煤与瓦斯突出危险性.

| Abstract: | In order to study the feasibility of the electromagnetic emission technology applied to predict coal and gas outburst occurred in the seam with soft roof,soft coal and soft floor,basing on the experiment studying the electromagnetic emission from the coal and rock the- ology failure,a KBD5 monitoring and measuring instrument was applied to make the dynamic tracing monitoring and measuring in the mine.Then there was a comparison and analysis between the measured results and the conventional predicted index.T... |
