摘要
基于煤与瓦斯突出流变—突变机理,探讨了金佳矿7#煤层掘进工作面采用放炮后落煤瓦斯涌出量动态指标预测突出危险性,确定了指标临界值,并介绍了初步试验效果。
Based on rheologic and mutative mechanism of coal and gas outburst,this article discusses the forecast of outburst danger of in 7# coal heading face of Jinjia mine by adopting coal and gas outburst volume dynamic index after blowing out..It determines the index critical value,and also presents the tentative testing result.
