Coal Stockpile Height

Coal Stockpile Height

Jun 02, 2015 I am working on a project in Indonesia for a coal export terminal. The volatile material content in coal is 39 . I read somewhere that this is considered as high volatile and the stockpile height should be restricted to 4 m. In that case I will have to have very long stockpile. I have designed the system with 15 m heigh pile. Open to forum for guiding on best solution.
