New Technique of Coal Bunker Construction in Lower Section of Buertai Mine

In order to further guarantee the long-term stability in the production process of the large section coal bunker in Buertai Coal Mine, on the basis of summarizing the traditional construction technology of the coal mine, the construction technology of the coal bunker and the actual situation in the production of Buertai Mine are analyzed on the basis of the stability control theory and the rock mechanics theory of the mine. The new construction technology of large section coal bunker is discussed. The field construction results show that the new construction technology achieves good results and ensures the stability of the large section coal bunker.
