A great resource for mining information, including accident reports, mine inspector reports, deaths and newspaper reports is Scottish Mining Website. This is a virtual treasure trove of information. You can search by surname, accident, year or parish.
Note that if your miner died as a result of a "roof fall" (the roof of the mine caving in) then it is unlikely that there will be a mine inspectors report. The reason being that roof falls were fairly commonplace and to inspect every accident would have been too time consuming for the limited number of inspectors. Two of my miners were killed together, father and son, in 1872 at Greenfield Colliery. At the time, I had been unable to locate the mine inspectors report, so contacted the website by e-mail. In return, I received not only the mine inspectors report but also newspaper articles relating to the accident. So, don't hesitate to ask for help if you are having difficulty finding information on your miner. Please note, however, that these wonderful volunteers are not able to do your research for you.
Happy Ancestor Hunting!
