In materials such as rock or concrete, there is a need to protect the cone of potential F.2.1.11 failure around each anchor device. This cone is usually considered to have a maximum radius equal to the depth of the installed anchor, including any structural anchor, and thus affects the minimum spacing between the anchor devices: see Figure F.2. Attention is drawn to the need to take account of the effect of increased Y angles if the spacing between anchor devices is wide: see Part 2, 2.11.2 and Part 2, Figure 2.4.F.2.1.12Other factors that need to be addressed when deciding upon the spacings include:a)the strength and nature of the base material;b)the ability to share the load equally between the anchors.
