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。
Coal and gas outburst are major disasters in underground mining in coal mines around the world and are more common as mining depth increases and tunneling speed increases. In the past one or two decades, many countries have done a great deal of work on the prediction and prevention of coal and gas outburst and have achieved some success. In order to make more progress in the prediction of our coal and gas outburst and to ensure the safe production of coal mines, this paper discusses the general situation, geological factors and prediction methods of coal and gas outburst in coal mines of the world’s major coal producing countries, Theoretical research and development trends. As for coal and gas outburst prevention work will be introduced later.
