摘　　要：新建矿井的煤与瓦斯突出危险性评估是矿井初步设计的重要依据,同时对于今后矿井建设期间井筒、井底车场揭煤具有重要的指导意义。文章以新建矿井信湖煤矿为研究实例,分析了井田地质构造、岩浆岩侵蚀、煤层顶底板岩性及瓦斯风化带对煤层突出危险性的控制影响,利用矿井勘探期间瓦斯数据及邻近矿井瓦斯赋存规律研究结果预测了新建矿井煤层瓦斯参数,并对新建矿井煤层突出危险性进行了评估。The coal-gas outburst dangerous pre-evaluation of a new mine is the basis of preliminary design.At the same time,it has an important guiding significance for the new coal mine construction during the wellhole,pit bottom uncovering coal in the future.Based on the newly-built Xinhu Coal Mine for an example,the effect of newly-built coal mine field geological structure,the invasion of magmatic rocks,the properties of rocks and gas weathering zone,on the outburst dangerous is analyzed.Using gas data during mine exploration and nearby mine storage rule forecasts coal seam gas parameters and makes coal-gas outburst dangerous analysis of new coal mine.
