1.Abstract: The control of the coal and gas outburst in coal mine is a very comples systematic engineering,and the regularity of coal and gas outburst is explored successively from unknown to known.The artificial calculation could not be suitable for the need of processing and analyzing a lot of data.When the computer database and plotting function use to the control work of coal and gas outburst,they can better processing the outburst data,increasing the direction and accuracy of the outburst prediction,and better serving the safety mining.
文摘:煤矿防治煤和瓦斯突出是一项极其复杂的系统工程，人们逐步探索煤与瓦斯突出规律，人工计算已不能适应大量数据处理与分析之需要，将计算机数据库及计算机绘图功能运用于防突工作中，能较好地处理防突数据，提高防突预测预报的针对性和准确性，使之更好地为矿井安全生产服务。
2.and the decrease of the outburst coal permeability is most among the three, meanwhile that of the delay outburst coal permeability takes second place, and the non-outburst coal permeability is least in AEF.
交变电场作用使煤的渗透率增大 ,而且突出煤样的渗透率增大最多 ,延迟突出煤次之 ,非突出煤最少。
3.EG Cancri is a CVs that has large - amplitude outburst (7mag), slow decline from outburst, long intervals between outburst and short period. From above properties, we classify the CVs, EG Cancri, as a WZ Sge type DN is plausible.
由于EGCnc具有大变幅爆发（≈7mag），缓慢下降，爆发间隔长（19年），极短轨道周期和superhump等特征，我们认为这是一颗较少见的WZSge型矮新星。
4.Introduce the gas outburst prediction technique by using gas abnormal effusing when gas outburst is gestating.
摘要介绍了瓦斯突出孕育过程中瓦斯涌出异常特征，结合计算机软件进行瓦斯突出预报。
5.For the tectonic coal，the properties of higher porosity and lower permeability make it capable of keeping higher gas pressure；Both of the “isolating action” and “gas-cushion action” cut down the resistance against outburst；The specifity of high-defomed-extent makes desorption，escape and flowing quickly become possible；The existing of weak-seam or “thoroughfare-seam” create suitable conditions for the initial erupting and continued developing of coal and gas outburst.On the whole，it is the synhesis action of all factors，which leads to outbursts.The existing of tectonic coal with certain thickess is the essential condition of coal and gas outbursts，but not the sufficient condition.
高空隙率、低透气性使构造煤能够保持较高的瓦斯压力；破碎性、“隔离”作用及“气垫”作用，使构造煤抵御外力作用的能力大大降低；构造煤变形幅度大的特性，为瓦斯的迅速解吸、放散和快速流动创造了条件；构造煤薄弱分层或“通道层”的存在，则为煤与瓦斯突出的初始激发和持续发展奠定了基础；上述因素的共同作用，影响和制约了煤与瓦斯突出的强度和分布.尽管如此，一定厚度的构造煤的存在只是发生煤与瓦斯突出的必要条件和有利条件，而非充分条件.
6.The software realize the exceptional messages extract of gas concentration data, and display abnormal symptom of gas concentration change trend and scope by real-time graphics before gas outburst, can reflect the forepart signal of the gas outburst, give a significant guide for reduce the loss and ensure safe production of coal mine.
利用软件实现了叶瓦斯浓度数据中异常信息的提取，并通过图形形式实时显示突出前夕瓦斯浓度变化趋势、幅度等异常征兆，可直观、明了地反映突出早期信号，对防治突出，减少事故，确保煤矿安全生产有重要的指导意义。
7.The progress trend for predicting the coal and gas outburst is to locate the zone of intensive deformation and fracture with AE technology, non contact and continuous predicting the outburst with EMR technology, combined with dynamic emission of the gas attained by the environmental monitoring system.
未来煤与瓦斯突出预测的发展趋势是 ,利用声发射监测技术对变形破裂剧烈区域进行定位 ,利用电磁辐射监测技术工作面非接触连续预测 ,再结合现有的环境监测系统监测的瓦斯动态涌出对煤与瓦斯突出现象进行准确预测
