I found the following information in my search of my Wyoming mining accident database:

Date of Accident / Name of Victim / Age / Mine or Location / F=fatal or N=nonfatal / Reference Source / Page / Report Year


1923AUG BELL, C H SUPERIOR N 73 28 1923
1923DEC BELL, JAMES SWEETWATER N 73 24 1923
1960FEB BELL, ROGER ELMO FREMONT CANYON N 74 57
1970AUG BELL, S S RIVERTON N 74 71 1970
1939SEP BELL, W E DINES N 73 62 1939

If any of the above are of interest to you, get back with me. I do have a little more information about these specific accidents.
