The determination of the type of support under complex seam condition

This paper take the mine 1351 working surfaces as an example, according to this working surface's geological condition, had determined the reasonable support working resistance and the corresponding supports and protections parameter. Through initially supports the strength and the working resistance statistical analysis to the working surface support, the results show that under complicated seam's geological condition, the choice support controlled the fault cutting destruction roof in the use process, support's load bearing performance also obtained the full display, the stress good shape, and the working surface is safe in production. This research results have the important reference value under similar complex geology's other coal mine.
