Abstract: In order to solve the problems of soft and hard rock laminated roof separation failure and poor stability, this paper
analyzed its unique characteristics, designed reasonable roadways according to the mathematical formula, defined the parameters
and layout modes of bolts and anchor cables, effectively controled the roof separation in the actual project, and ensured that the
roadway surrounding rock was in a stable support state, which provides a favorable basis for similar projects.

Key words: soft and hard rock laminated roof; separation failure; support parameters; layout mode
