This Bureau of Mines publication is designed primarily to provide mine engineers and production-level mine managers with the following: (1) information to assist them in making the decision to retreat mine and in selecting the best retreat mining technique for specific mining conditions. (2) Information on mine planning that will enable them to design mine layouts for safe and efficient retreat mining. (3) Information that will enable them to develop a section foreman's handbook. The manual has been organized to gradually increase in level of detail as the reader progresses from beginning to end. Individuals interested in an overview of retreat mining can confine themselves to the first few chapters. Those interested in mine planning should read the middle chapters as well. Those interested in the development of a foreman's handbook should read the entire manual.
