摘　　要：总结分析了皖北前岭煤矿煤与瓦斯突出现象及基本特征，确定了同一井田在煤层瓦斯含量等相近的条件下，煤体结构的破碎是影响煤与瓦斯突出的主要因素。提出了在煤层滑褶构造区。Analysis is conducted of coal gas bursts in Qianling Coal Mine of Northern Anhui and their major characteristics. Conclusion is drawn that, factors such as gas content being similar within the same minefield, coal and gas bursts are chiefly due to coal-body structures broken. It is pointed out that strong bursts are likely to occur where residual stress builds up at the front of slide and seams are thickened.
