摘要
对井下发生煤与突出后巷道断面变化及瓦斯涌出突然增大给瓦斯涌出量计算带来的影响进行了研究,结合采煤工作面发生煤与瓦斯突出后现场情况的调查,提出了利用瓦斯监控系统瓦斯浓度实时数据和峰值移动时间,采用定积分近似计算对数据进行处理,得出了准确定量分析井下煤与瓦斯突出后瓦斯涌出量变化的方法。
The influence of the change of roadway section and sudden increase of gas emission after occurrence of underground coal and gas outburst on the calculation of gas emission is studied.Combining with the site investigation of coal mining face after coal and gas outburst,it is proposed to process the data by using definite integral approximate calculation based on the analysis on the real-time data of gas concentration and peak moving time of gas monitoring system,by which the method of accurate quantitative analysis of the change of the amount of gas emission after underground coal and gas outburst.
