一、煤与沼气突出概述煤与沼气(二氧化碳)突出(简称突出)是煤矿采掘过程中发生的一种复杂的动力现象,是指在很短的时间内(几秒钟)煤与沼气自煤体中突然向采掘空间抛出,抛出煤炭可达万吨以上,喷出瓦斯达数百万米~3。抛出的煤炭,瞬间即可堵塞巷道,破坏通风系统,瓦斯并可逆风流扩散数千米,甚至可 I. Outburst Overview of Coal and Biogas The highlight of coal and biogas (carbon dioxide) is a complex dynamic phenomenon that occurs during the coal mining process. It refers to the coal and biogas generated from coal in a very short period of time (a few seconds) The body suddenly thrown into the extractive space, throwing coal up to more than 10,000 tons, emitting hundreds of millions of meters of gas ~ 3. Thrown out of coal can instantly block the roadway, destruction of ventilation systems, gas and wind flow can reverse the proliferation of thousands of kilometers, or even
