Abstract: Directed against the unreasonable phenomena existing in the construction layout of coal industry square facilities, this paper, adopting the SLP method to have a correlation analysis of the logistics, flow and emergency department, drew the location diagram and area diagram for the facilities. Through evaluation of the construction layouts before and after optimization with weighting factor method, the applied effect of SLP in the layout was demonstrated. Meanwhile this paper provided a new construction mode of coal industry square facility layout for the coal mines with frequent disasters.

Key words: Coal industry square, emergency department, systematic planning layout, correlation table
