Alarming outburst of gas at Denaby Main colliery.
A serious outburst of gas took place at the Denaby Main Colliery, on Monday afternoon, which fortunately was not attended with fatal results.
The outburst took place in the North East part of the workings, and was so dense as to extinguish the safety lamps for a considerable distance, but luckily they were all in good condition or otherwise a very serious calamity might have occurred, there being upwards of 400 men and boys in the mine at the time.
The men naturally became alarmed at once rushed to the bottom, some of them being almost naked, and were drawn to the surface.
A man and a boy who missed their way were afterwards discovered by the manager and other officials, who at once descended the shaft and they were soon brought to the top.
Great excitement prevailed and became known what had occurred but this was removed when it was known that all the men had were safe .
