国外煤矿煤和瓦斯突出概况和预测方法

煤和瓦斯突出是世界各地煤矿地下开采的主要灾害,随着开采深度的增加和掘进速度的提高,更为常见。近一、二十年许多国家对煤和瓦斯突出的预测和预防做了大量工作,并且取得了一定的成效。为了在我们的煤和瓦斯突出的预测工作中取得更大进展,保证煤矿安全生产,本文论述了世界主要产煤国煤矿煤和瓦斯突出的概况、地质因素和预测方法,以及当前在应用研究和理论研究方面的情况和发展趋势。至于煤和瓦斯突出的预防工作以后将另文介绍。

A Survey and Prediction Methods of Coal and Gas in Foreign Coal Mines

The outbursts of coal and gas are major hazard to under- ground coal mining in many parts of the world,and have become increasingly common as both mining depts and rates of advance increase.In the last ten to twenty years many countries made a lot of research on prediction and prevention of the outbarst and obtained some success.In order to gain still greater success in our out- burst prediction and to ensure the safety in production of coal mine, this paper discussed the survey and the geological facfors as well as the prediction methods of outburst of coal and gas in these countries,and its situations and developing trends in applied re- search and pure research nowaday.As for the outburst prevention will be introduced later.
