Model Mine at Exposition

More attention to the details OF mining will be shown at the Pan
ama-Paci6c exposition at San Francisco in 1915 than at any exposition
ever held in the United States before. This, of course. will be due to the
great interest of the western states in the mining industry. 1t will be
a novel feature of the exposition-if not the most novd-and will no
doubt attract unusual attention from eastern visitors. The description
of the expoitions model mine, prepared by a technical expert, will be
found interesting. 1t runs as follows:
Beneath the floor of the palace of mines and metallurgy, there will
be constructed a model mine. From either side of two main parallel
drifts there will be, on one side, model coal-mining rooms, and on the
other side, model metal mining slopes, each of such dimensions IS may
be appropriate to the mine represented. The mine drifts and working
places will be outlined in metal lah, plastered with cement plaster, and
in this will be embedded the appropriate re and wall-rock, or coal, or
slate, as it occurs i'll the several mines represented. The mine is. to be
truly cooperative, each exhibitor bearing his portion of the expenses.
There will be reproduced metal mine slopes illustrating mines in
such characteristic districts as the Mother Lode, California Comstock
or Godfeld, Nevada; Occur dAene, Idaho; Anaconda, Montana
Mesabi, Minnesota; Gogebc, Michigan; Joplin, Missouri; Bisbee, Ai-
IONA and Franklin, New Jersey; and typical coal mines from various
parts of the country.
These will be provided by the nine owner or groups of owners
concerned in such a manner as to reproduce a accurately as possible
the interior appearance of such working places as they occur in their
mine. The makers Of mining machinery Or appliances in use in each
particular mine are to place in the model mine such machinery as they
sell to the mining company concerned. The cost to each party invov d
will be mconsiderable. 1t is estimated at a minimum OF about $500. The
manufacturers will place in the various mine slopes o rooms the mining
machines or appliances which they sell.
The bureau Of mines will, through its engineers and other per-
manent employees, transaet. the business connected with constructing and
operating the cooperative mine, furnish the necessary engineering
superintendent during construction and operation, and will, if desired,
supervise the placing of the materials and tinbering, or the mining
machinery, in the several mining rooms or slopes.
The entrance to the mine will be through the bureau of mines
space in the mines and metarurgy buildings. Visitors will be given
portable mine lamps, and will be lowered in a mine cage which will move
very slowly to the level of the mine floor beneath the building floor. a
panoramic effect Of the strata and lining OF a mine shaft will move by
them rapidly 50 Is to produce the illusion of descending a considerable
depth. Passing into the main drift they will come to the various mines,
the names and locations of which will be displayed, and they will SCI the
mining machinery and appliances in place a S shown or demonstrated by
the makers.
The only concern the bureau of mines has i'll this, and the chief
concern which nine owners o machinery makers can have in it, is q
public spirited and cooperative interest in the welfare of the mining in
dustry as a whole, and an unusual opportunity to illustrate to a vast
audience the extent, diversity, completely and expense of conducting
mining operations throughout the United States.
