mortar.
MINER'S SPOON
The miner's spoon is used to lift material out of narrow
deep holes, in order to clear for further drilling or to
permit placing of explosive charges. The miner's spoon
is a slender metal rod with the ends forged into small
bowl-shaped projections at right angles to the rod.
BLOCKS
Blocks are used in combination with rope and wire to
hoist and move loads. The block consists of a metal
shell which supports both ends of a pin. The shell also
houses a grooved pulley that revolves on the pin.
Attached at one end of the first block is a freely revolving
hook. Blocks may be classified as single, double, triple,
etc. according to the number of pulleys housed in the
shell of the block. Depending on the various
combinations of blocks available to do the job, the
mechanical advantage can be increased indefinitely.
