NANAIMO – Workers check the progress of a concrete pumping operation to fill coal hole.

Workers, lower left, peer into a coal mine shaft Tuesday to check the progress of a concrete pumping operation to fill a portion of the void discovered under Pine Street several weeks ago.

A large lump of concrete, seen just to the left of a new water pipe at lower right, is evidence of a previous attempt to fill the shaft that was discovered during excavation work Monday.
