Packing fractions and average contact numbers of random packings of circles have been calculated with the Monte-Carlo method simulation by a computer.<BR>Circles were put into a rectangular container in order. The bottom of the container was taken as x axis and circles were put into the container alongy axis. The circles were assumed to be under a static force field along y axis and directed towards the bottom, and to roll down to dynamically stable positions and settle there.<BR>Obtained results were compared with three dimensional packings of spheres and it was considered that our results on two dimensional packings correspond to those on observed packings of steel balls.<BR>Calculations on the random packings of mixtures of circles of two different sizes and of those with normal size distributions of various standard deviations were performed.
