瓦斯含量法预测突出危险性的试验研究

Experimental Study of Using Gas Content Technique to Predict Outburst Hazard

介绍了瓦斯含量法预测突出危险性的基本原理和煤层瓦斯含量快速测定方法,研究了基于瓦斯含量法煤与瓦斯突出预测敏感性,探讨了突出预测临界初值。实现了煤层瓦斯含量直接快速测定,瓦斯含量测定时间一般不超过8h;瓦斯含量法预测突出具有良好的敏感性,技术上可行。

This paper described the basic principle of predicting outburst hazard with gas content and the quick measuring method of gas content in coal seam, made study on the sensitivity of coal and gas outburst prediction based on gas content measuring method, and probed into the initial critical value of outburst prediction. The direct and quick measurement of gas content was thus realized. The measuring time of gas content was not excess of 8 hours generally; applying gas content method to predict outburst has better sensitivity and it is feasible technically.
