I was wondering if miners who worked for companies during the Gold Rush used some sort of safety features in case of an emergeny. Also do miners receive compensation if they receive an injury from a mining accident?
The hallmark of the California Gold Rush was that small groups of men (and sometimes women) worked as teams at placer mining. They did not work for corporations. When the term "company" was applied, it referred to the small company of miners. Since they were partners - and sometimes friends - there was a tendency for them to care for another when injured or ill. Your question seems to focus on the corporate, hydraulic or hard-rock mining that followed the classic California Gold Rush.
