I currently have over 600,000 mining accident records (fatal and nonfatal) covering most of the United States. However, about 283,000 of the mine accident records are the state of Pennsylvania. The mining accident records are from the late 1800s through the early 1900s. I have knowledge of all major mine disasters in the U.S. I can also provide advice on finding U.S. mine fatalities from the late 1960s and later. The best way to contact me is to leave a message for me through my website http://miningaccidents.weebly.com/ which has a state listing of all my mining accident records, “Mining Accidents U.S., Canada, Australia & New Zealand” , click CONTACT at the top of the web site or email me through this web site.
