In this thesis, Shanxi Luan Environmental Energy AG Wang zhuang Coal as the basis, with theoretical analysis, numerical simulation of an integrated approach designed to stay on the optimal size of coal pillars, supporting a systematic program of optimal design, Reduce the loss of coal mine and to ensure safety efficient production, Used in the process of deep mining remain narrow pillar gob technology, Proposed the scientific and reasonable determination of pillar size, to ensure stability along the roadway. And put forward along the roadway of the high strength bolting technology, It is shown by a small pillar to protect road and high strength bolting method in theory can effectively guarantee the stability of deep along the roadway.
