摘　　要：钻孔瓦斯涌出初速度(q值)是预测煤与瓦斯突出的重要指标之一,因此降低钻孔瓦斯涌出初速度可以有效的解决瓦斯突出危险。通过对七台河新兴矿41061工作面进行深钻孔注纯水以及表面活性剂试验,得出:煤层注水中添加表面活性剂能够有效的抑制煤体中瓦斯的解吸速度,为解决新兴矿井的瓦斯突出问题做出了贡献。Initial velocity of gas emission from borehole is one of the most important indexes for the coal and gas outburst prediction,so it can solve the risk of gas outburst effectively to reduce the initial rate of gas emission in drill hole. The results were applied to 41061 workface of Xinxing Mine in Qitaihe and the results showed that： it can inhibit the velocity of gas desorption to add surfactants into the seam water,which make a contribution to outburst of Xinxing mine.
