ACREAGE MINED.—During the year there were<br />
excavated 3,967.9 acres of coal.<br />
In the past eight years the mines of the state<br />
have depleted the coal deposits by 22,316.2 acres<br />
as shown below:<br />
Total acreage for the eight years from 1897 is<br />
as follows:<br />
1897 1,733.9 Acres.<br />
1898 2,184.5<br />
1899 2,361.2<br />
1900 2,638.8<br />
1901 2,854.6<br />
1902 3,353<br />
1903 3,222.3<br />
1904 3,967.9<br />
Total 22,316.2 Acres.<br />
ACCIDENTS IN MINES.—During the year there<br />
have been no great disasters at the mines in the<br />
state, a statement which it is a great pleasure<br />
to be able to make. There were, however, a number<br />
of accidents, which are always incident to<br />
the operation of coal mines. A very large percentage<br />
of the accidents were due directly to<br />
carelessness on the part of the persons injured<br />
or killed. A personal investigation into a number<br />
of fatal accidents would almost lead to the<br />
belief that they were deliberate suicides. By<br />
causes the fatalities were: by falls of roof, 95;<br />
explosions of gas, 3; mine cars, 22; and by all<br />
other causes, 20; a total of 140 fatalities.<br />
Of the 140 fatal accidents, 123 occurred within<br />
and 17 without the mines, and of 211 non-fatalities,<br />
191 were inside and 20 outside of the mines.<br />
For each 295 persons employed within the<br />
mines of the state in 1904, one employe lost his<br />
life by accident, or for each 1,000 employes inside<br />
3.38 persons were killed by accident, this being<br />
1.44 less than in 1903.<br />

The greatest number of accidents are caused<br />
by falls of roof within the mines, and until<br />
greater care is exercised within the mines there<br />
will be no abatement in the number of fatalities<br />
from this cause.
