Impact of setting load on bearing capacity of props in a powered support unit
Journal Title: Mining – Informatics, Automation and Electrical Engineering - Year 2016, Vol 528, Issue 4
Abstract
Experience acquired for a number of years proves that the fluidity of production processes in longwalls depends on proper support of the excavation roof. A properly matched power support unit is not enough to guarantee good support of the excavation roof, particularly in its face part. Irregularities in the maintenance of the longwall roof may be related to some errors in the control of the power support unit, mainly in setting the unit with too low initial pressure. With respect to the above issues, the article features an analysis of the setting load impact on the bearing capacity of props in a power support unit.
