Abstract:

Article Preview

Based on bolt support project of the 107th working face in Huangling the 2nd mine, the lesion range of large-span rectangular coal roadway is defined by the equivalent ellipse method to determine the support parameters. Site monitoring results indicate good support effect and correct support parameters. This paper provides new effective approach to support scheme for large-span rectangular coal roadways.
