Another key clue connecting the rock waste layers to mining is industrial archaeology. When we carefully examine the layers at the Blast Beach, we find direct signs of mining activity. For example, one piece of evidence might be pit props. These wooden props were used to support the roof sections of tunnels and shafts under the sea.
We can also see conveyor belts made of rubber, which were used to transport coal to the surface. Sometimes, you might even spot miner’s boots or parts of old railway tracks. In the past, these railways were used together with pit ponies to transport coal. Historical photos show miners and their pit ponies moving coal along these early railway lines. All these findings help us understand the history of mining in this area.
