Classification of Surrounding Rock of Bolt Supported in Coal Mine Roadway

Abstract:

Classification of Surrounding rock of roadway of Coal mine bolt supporting is the basis of bolting design, To scientifically design coal roadway bolting, classification of surrounding rock of coal roadway bolting must first be carry out. in this paper, the comprehensive application of knowledge engineering, rock mechanics, we developed the surrounding rock classification system for the bolt support of coal mine roadway engineering, the surrounding rock classification system is practical easy to use, the bolt supporting of roadway surrounding rock classification results to the coal mine roadway bolt support has important significance and practical value.
