A pan (10) and a pan system (100) for surface control of wall and/or roof material in a subterranean tunnel or room, the oval pan (10) having a convex central portion (20) held at an angle above a horizontal plane and an outermost edge angling downwards and meeting a planar pan edge portion (14) lying in the horizontal plane, both edges meeting at a transition point (16). The central portion includes a plurality of parallel concave rib members (18) arranged to span the shortest width of the pan. In use as a system (100), a bolt (40) drilled though a support plate (3) and the pan secures the pan system to the wall or roof. The force exerted onto the bolt transfers to the pan results in a dimpling of the central portion, allowing for a tighter application of the pan to the wall or roof.
