摘　　要：为了对煤与瓦斯突出进行实时监测,在研究中采用了数据来源丰富的瓦斯监控数据.在对新安煤田煤的瓦斯解吸特征实验室研究的基础上,采用新安煤田始突瓦斯含量和瓦斯涌出的分源预测技术,研究了煤层瓦斯含量和瓦斯涌出量之间的关系.研究结果表明:新安煤田的煤具有在短时间内快速解吸的特点且瓦斯解吸速度衰减的快,结合新安煤田的采掘工艺,当掘进巷道的瓦斯涌出量达1.03 m3/min时,非突出煤层即升级为突出.按新安煤田掘进的通常配风量,掘进巷道的瓦斯监控系统中的瓦斯体积分数达0.34%时,掘进巷道需进行连续的区域验证.In order to continuously monitoring coal and gas outburst,the data of gas monitoring is used in our study.Based on the characteristics of gas desorption of Xin＇an coal field,the original outburst gas content and predicted method by different gas source,the relation between gas content and gas emission rate is studied.The results show that the coal in Xin＇an coalfield has the characteristics of rapid desorption and its desorption rate is decayed rapidly.Considered the mining process,when the gas emission exceeded 1.03 m^3/min,the coal seam may be upgraded and become an outburst seam.Considering the wind,when the gas concentration reaches 0.34% in an active entry in gas monitoring,continuous regional validation must be used in this entry.
