摘　　要：针对工作面煤与瓦斯突出预测方法的研究现状,介绍了接触性预测和非接触性预测2类方法。通过对2类方法的原理以及实际应用的效果进行论述与分析,总结了各自的优势与不足:接触性预测方法测量方法简单,但工作量大、准确性较低;非接触性预测实现了连续动态监测、预测准确性较高,但部分理论不够完善、设备不能满足现场需求,仍需继续深入研究。结合了2类方法的优点及技术现状,提出了工作面煤与瓦斯突出预测方法的未来发展的趋势。Aiming at the current research status of coal and gas outburst prediction methods in workface,introduces two main methods:contact prediction method and non-contact prediction method.Discusses and analyzes the principles and the effects of practical applications of the two types of methods,and summarizes the advantages and disadvantages of them:contact prediction method is simple,but the workload is large and accuracy is low;non-contact prediction achieve a continuous dynamic monitoring and its accuracy is high.However,some of the theories are not perfect enough and the equipment cannot meet the needs of the site,and further research is still needed.The author combines the advantages and technical status of the two types of methods,and proposes the future development trend of coal and gas outburst prediction methods in workface.
