- Abstract
layered rock mass is a common geological structure in the underground engineering construction, and the Protodyakonov's theory is widely used in the calculation of underground caving arch, however, the actual occurrence state of engineering surrounding rock is much more complex than homogeneous rock mass of the Protodyakonov's theory. Firstly, researching the influence of span and rock hardness coefficient of the arch line equation under the Protodyakonov's theory on the shape of pressure-arch respectively, then dividing the horizontally-layered strata into two strata which are upper-hard lower-soft ground and upper-soft lower-hard ground, researching the forms of the pressure-arches for two strata based on the Protodyakonov's theory. The purpose is to provide the scientific guidance for roadway support of the 11912 working face of the Xingtai mining area.
