Morphology

heading = head (opaque) = head + ing

Although it is formally built from head + -ing, the mining sense is a specialized technical term that ordinary learners are unlikely to infer from the base word alone.

Etymology

Heading comes from the common word head, which means 'front' or 'top'. In mining a heading is the front passage miners dig, so it is the 'head' of the tunnel.
