In this paper, the research and development of the distribution of air-holes in the groove of
air-cushion belt conveyor were introduced. The expressions of air-cushion pressure were given and
the graph of it was shown as well. The air flow model nearby groove-holes and air outflow model on
cross section were given too. In the same time, the distributing mode of equidistant air-holes with
unequal diameter was studied and analyzed. In order to make up the shortage of the study on air-hole
distributing mode of equidistant air-holes with unequal diameter on the air-cushion belt conveyor, an
instance of the air-cushion flow field was numerically simulated based on the CFD software ,Fluent
software. Several groups of data of different air-hole distributions, (for example, the center distances
of air-holes in the groove of air-cushion belt conveyor are the same as each other and their diameters
are different), were selected to compare with each other , and then, the results were compared with
existing theory. According to the different results of the numerical simulation on the distributing
mode of equidistant air-holes with unequal diameter, the optimal parameters of air-hole distributing
mode were obtained, and the effect of prevent offset that comes the balance groove-hole on
air-cushion belt conveyor. Moreover, the verification to prove the agreement between the results of
numerically simulated and basic theory was carried out by the comparison analyses. The theoretical
feasibility of air-hole distributing mode of equidistant air-holes with unequal diameter was analyzed.
