摘要：
According to the influence of the combination of short-distance coal seam groupon mining roadway, using numerical simulation software FLACto draw the abutmentpressure distribution ahead the working face and the area of influence in fully-mechanizedmining conditions, the variation rules of surrounding rock supporting pressure of floorroadway and the deformation rules were summarized.GYS-300 anchor dynamometer wasused to measure the roadway surface displacement, and the conclusions of numericalsimulation were verified.
