瓦斯解吸量在突出预测中的可靠性研究

Reliability Study on Gas Desorption Volume in Outburst Prediction

采用现场测定和实验室实验的方法,研究得出了瓦斯解吸量作为突出预测指标是敏感可靠的。突出煤体的瓦斯解吸量大,瓦斯解吸速率快,瓦斯解吸量和瓦斯压力之间有着密切的关系,本文提出通过研究解吸时间、瓦斯压力、瓦斯解吸量等之间的关系,来确定瓦斯解吸量的临界值的方法。

With the methods of scene testing and laboratory tion amount as the outburst prediction indicator is sensitive and experiment, the research obtains that the gas desorp- reliable. The gas desorption quantity of outburst coal is large, gas desorption rate is fast, the gas desorption quantity and the gas pressure has a close relationship. In this paper puts forward that through studying the relationship between desorption time, gas pressure, gas desorption quantity and etc. , determines the critical value method of gas desorption quantity.
