打钻过程中瓦斯涌出的数值模拟研究

Research of Gas Emission during Boring Process by Using Numerical Simulation

为了解钻孔过程中瓦斯涌出的规律,利用ANSYS软件进行数值模拟,得到在打钻过程中瓦斯涌出速度和涌出量的规律及特点,并且分析可能产生这种规律的原因,通过研究其规律和原因,将有助于提高预测突出的准确率,避免在打钻过程中瓦斯突出等事故的发生以保证井下工作人员的生命安全。

For knowing the basic features of dynamic gasemission during boring process,using ANSYS software to simulate. The regularity and characteristics of gas emission rate and emission amount during boring process were obtined.By studying its regularity and reasons, the accuracy of outburst prediction will be favorably increased. avoiding the occurrence of gas outburst and other accidents during boring processto ensure the safety of the workers in the underground.
