Abstract: In order to obtain the mine strata pressure law during the high cutting coal mining face passing through a fault,based on No.22526 high cutting coal mining f ace in Halagou Mine of Shendong Mining Area as a case,a site observation and theoretical analysis method were applied to analyze the fault passing process and the mine strata pressure behavior law was obtained during the 5 m high cutting coal mining face passing through the fault. The results showed that due to the existed fault reduced t he strength of the rock in the area and destroyed the completed strata,thus the periodical roof weighting strength was reduced and step distance was reduced. The working resistance curve of the powered support along the coal mining face during the periodic roof weighting in the fault area was in two humped camel type ,the resistance peak w as at the two sides of the fault. The working resistance curve of the powered support during the non periodic roof weighting was in single humped camel and the working re sistance of the powered support at the fault was relatively high. The spalling and rock leakage at the fault area was depend on the periodic roof weighting status and he sur round rock condition.
