Abstract: This invention relates to a composite type mine support pack and a component for building the pack. The pack components are identical with each including an elongated timber element, a first brick which is attached to the element adjacent its one end and a second brick which is attached to the element on the same side of the element and in alignment with the first brick in the axial direction of the element with the second brick being spaced from the other end of the element by a distance equal to twice the dimension of the first brick when measured in the axial direction of the timber element plus the distance by which the first brick is spaced from its end of the timber element. Preferably the bricks are made from timber. The pack consists of superimposed layers of the components with the bricks on each component resting on those of the components above and below it.
