摘　　要：为了安全有效地防治回采工作面上隅角瓦斯超限,根据多年实践经验,对几种常用的防治回采工作面上隅角瓦斯超限方法的原理及具体实施过程的进行了详细介绍,阐述了使用这些方法应注意的问题。实践表明:每一种方法都有其特定的使用条件,不同矿井回采工作面上隅角瓦斯超限又有各自的具体特点,必须具体问题具体分析。In order to effectively prevent gas overrun at upper comer of mining face, according to practical experience of recent years,the principles of preventing gas overrun methods at upper corner of mining face and the specific implementation process are introduced in detail, and the problems of using these methods should be noted are described. Practice shows that each method has its own specific conditions, and the gas overrun at upper corners of mining faces in different mines has their own specific characteristics, specific issues nmst be analyzed specifically.
