The protective canopy survey consisted of visits to 10 coal mines and to manufacturing of coal mining equipment. Mines with mining heights of 60 inches and higher were visited to evaluate protective canopy experience, operator acceptance, and to identify possible improvement areas. The report provides the results of the survey and evaluation of protective canopies-currently in use on coal mining machinery. It should prove valuable to coal mine operators and equipment manufacturers in providing guidance in complying with federal regulations regarding protective canopies in underground coal mines.
