摘要
对矿井煤与瓦斯突出预测方法的研究现状及发展趋势进行了论述。目前,我国大量使用的传统煤与瓦斯突出的预测方法,不仅花费了大量的人力、物力和财力,而且准确性较低。而声发射和弹性波探测技术等预测技术是很有前途的预测方法,这些方法实现了非接触连续预测,且预测准确度较传统方法较高。
Present situation of research and development trend of prediction methods for mine coal and gas were discussed. Currently, conventional prediction methods for mine coal and gas were widely used in China. It not only spent a great deal of labor power, material resources and financial resources, but also had low accuracy. Acoustic emission and elastic wave detection technologies were promising prediction methods. These methods realized non-contact continuous prediction and their prediction accuracy was higher than that of the conventional methods.
