The paper presents the findings of the investigative study on the contact zone of the tractive and carrying belts of the intermediate belt conveyor drive in cross section using thermal filming. The description of the test bench, conditions and sequence of the study is provided. The regularities of belt interaction are identified; particularly the irregularity of their adhesion in width in the contact zone, resulting in a number of primary longitudinally oriented areas. The location of the areas in cross section corresponds to the contact points of the belt sections with the roller ribs of supporting roller carriages. On the basis of the investigative study, the design procedure of the reduced factor of belt adhesion is developed. The procedure takes into account lumpiness of the loads as well, particularly probable bearing of the load particle layer adjacent to the belt directly through the edges. The paper shows the limitations within the context of the proposed procedure depending on the types of transported materials. The example of traction coefficient calculation is shown.
