Vanoord's remark about being shot while trespassing would seem to be true. I wrote this for the WMS Autumn 2007 Newsletter ...
Stay Out - Stay Alive WebsiteThis U.S. Department of Labor Mine Safety and Health Administration website mentions the startling fact that "Every year, dozens of people are injured or killed in recreational accidents on [U.S.] mine property." However, the statistics do not look quite so alarming when the actual reports (available on the site) are examined. The majority of deaths appear to be drownings due to swimming, diving or recreational boating in flooded quarries. A second significant category includes ATV and SUV accidents. There are also incidents where the term 'recreational' seems to be somewhat stretched and which one might hope would not happen in Wales. These include a trespasser on a mine site being fatally shot by a mine security guard, a fugitive from a police car chase being found hanging by his "bare hands" above a "treacherous 300-foot drop" into a quarry and another fugitive from a police chase falling down a mine shaft. However, despite the bizarre nature of some of the incidents, the reports provide an interesting insight into some of the issues involved when the safety of disused mines is discussed. Also, considering that mention is made of the headline statistic in the report on Statutory Nuisance Mineshafts ... it highlights the problem of comparing raw accident statistics from different countries.
