Abstract Based on the technology of similar material test and numerical simulation，the stability of large space structure in fully mechanized mining coal face is studied，and the relationship between the mining height and the stability of space structure is discussed. As an example，the technological parameters of coal seam No.3 in Sihe colliery of Jincheng coal corporation are optimized.

Key words： space structure of coal face stability simulation optimizing of technology parameters
