Abstract: The problem of flexural deformation and failure of the roof of laneway is prominet when a laneway is excavated in horizontal layered rock mass. Customarily, the deformation of roof is so large that it failures first and thus leads to the whole structure collapse. According to its special characters of flexural deformation and failure mechanism, the authors write a program with Matlab based on cosserats’ theory. By using the program, the deformation character and influencing factors are studied. The result indicates that the cosserats’ theory is suitable to simulating the laneway excavating in layered rock mass; and it is simple and convenient.

Key words: layered rock mass, laneway, cosserats&rsquo, theory, numerical modeling
