CH4-2主动抑爆系统在掘进工作面应用

摘要

掘进工作面出煤期间，落煤期间瓦斯从煤体中快速释放，容易导致工作面瓦斯积聚，因此掘进工作面能否有效抑爆显得十分重要。该文介绍了防止煤矿掘进工作面瓦斯、煤尘爆炸事故扩大的隔（抑）爆系统的组成、工作原理以及在潞安矿区的N1102胶带顺槽实验的模拟效果。%During the process of driving, the gas is quickly released from coal during coal falling, and it is easy to cause the gas accumulation in the heading. Therefore, it is very important to effectively suppress the explosion. The components and the working principle of the gas and coal dust suppression explosion (explosive-proof) system to prevent the accident expansion in the heading, the experimental simulation results in Lu'an mining area N1102 convey entry were introduced.
