MINE TIMBERING.
The square system of timbering, in use in most of our large mines on
the Pacific coast, was first introduced in Australia by Mr. W.H.
Patton, who adopted it in the Broken Hill Proprietary mines, although
it does not seem to be so satisfactory to the people there as to our
miners, who are more familiar with it. The accompanying description
and plans were furnished by Mr. Patton to the report of the Secretary
of Mines for Victoria:
"The idea is supposed to have originated in the German mines,
but in a crude form. It was introduced among the mines of the
Pacific coast of America some 20 years ago, by a gentleman
named Diedesheimer. Its use there is universal, and experience
has evolved it from the embryo state to its present
perfection. The old system and its accompanying disadvantages
are well known. A drive would be put in for a certain
distance, when it had to be abandoned until it could be filled
up with waste material and made secure.
