Hi Adrienne

Don't restrict your search to the IOM Times
Choose NW England - Laxey or Snaefell

The Manchester Evening News jas a Gunpowder Explosion Sept 1875 but with fatalities John & Robert Kelly (Laxey mine) no other injuries

The only other I can find with a Robert Kelly is the Snaefell Mining Disaster May 1897, in which it took amonth to retrieve the last body Robert Kelly

Good hunting
