Abstract : We study here numerically the average angle of repose θr and the packing fraction ρr of a random two dimensional heap of hard discs falling under gravity ballistically on a sticky base line, where the first layer of discs gets quenched in random positions. We find $\theta { m r}\cong52^\circ$ and $ho { m r}\cong0.80$ for such heaps. We also study the pressure or load distribution on the base line of such a random heap.
