I can only see a preview, however there seems to be a more detailed report in the Wigan Observer 27 July 1867.
From what I can see:
... on the body of John Ralph, oilman in the employ of Ince Hall Coal and Cannel Company, who was injured in the yard mine on the 6th inst. The deceased was engaged with another man in erecting cabin, when a fill roof took place, and he was caught. His companion escaped. Ralph died on Friday morning the 19th instant. A verdict Accidental Death was returned."
