A miner can be seen drilllng a hole for the charges. He is using a hand ratchet drill, the improvised platform he is standing on looks perilously shaky. David Richardson tells us: ”Image from Eston Mine, a miner drilling a shot hole in the thick seam district (with an average height of 16ft) using a hand rotary drill (likely a Blackett Hutton). Taken around 1925.” Craig Hornby now confirms the date and the reason for the image with: ”Eston 1920 for ‘Iron & Steel Trades Review’”.
