由残存瓦斯量确定煤层瓦斯压力及含量的方法
Determination of Gas Pressure and Gas Content Based on Residual Gas Quantity of Coal Sample
摘要
Abstract
In this paper, the residual gas content affected by coal size and gas pressure is investigated. Experiment results show that the coal size has a marked effect on residual gas content and a larger size has a large residual gas content. When the coal size is too large or too small,the residual gas content tends to a constant. The study also shows that the residual gas content has a power function relationship with gas content and gas pressure. Based on this law, after measuring the residual gas content, the gas content or gas pressure can be determined combining the known relationship between the residual gas content and the gas content or gas pressure. This provides a new convenient method for determining gas pressure and gas content, especially for the outburst coal seams. And its credibility has been validated in Qinan coal mine.关键词
