COAL RESERVES IN ARMSTRONG COUNTY, PENNSYLVANIS
° BY
Introduction,
In connection with the "Introduction to the Bituminous Coal
Pields of Pennsylvania" now being prepzred for publication by the
Pennsylvania Geclogical Survey, coal reserves of the bituminous
Tieids are being computed by Mr. John ¥. Recse. In order to render
this information available at once without waiting for the uncertain
Gate of printing the report, an abstract of Mr. Reese's figures for
Armstrong County is given herewith. All of the information readily
‘available at this time has been used in the computation, which
| followed the methods used by the Land Classification Boare of the
: United States Geological Survey in its valuation of the public coal
. Jands, The resuits are given by beds for each township. sor some
beds and for some areas the data are abundant and the results entire-
ly reliable. For other beds and areas the data are meager and the
results subject to revision as additional data are obtained. All the
data used and the computation sheets are permoently filed so that
modifications of the original figures can be made readily when re-
quired by additional information.
The figures presented are preliminary and subject to correction
for any srea when that area shall be studied in detail. In the mean-
time critical exsmination of the figures is invited in order that thc
results may be made as accurate as possible. To that end the Survey
Will welcome Every bit of information not now in its possession.
Records of drillings and other data will be kept strictly confiden-
tial if so desired, although the Bureau miturally prefers to be able
to use data freely,
George H. Ashley.

COAL PLD Ss
Armstrong County has six cosl beds that are now of economic
interest. In order of present importance as shipping cosls they are °
the Upper Freeport, Lower Kittanning, Upper Kittanning, Lower Freeport,
Pittsburgh, and Brookville.
Upper Freeport coal. The extensive development and outcrop of
this bed throughout the county have furnished many measurements of its
thickness, making possible en accurate estimete of quantity.
The percentage of this bed that can be recovered is governed by
the sequence in which the Upper and Lower Freeport coals are mined.
If the Lower Freeport bed is worked first and pillars are drawn, the
Overlying rocks will cave and break the Upper Freeport bed, thereby
Causing 2 partial smd in mony places complete loss of that "coal.
The Upper Freeport bed contains tlhe second greatest reserve with-
in the county, and is the largest producer, yielding more thon
3,500 ,000 +ons ejinuailly.
Lower Ai btannins ze conl. Ghroughout the townships in the northern
half of the cov Ricna this coal ouverops a fair amount of informa-
Gion 2s to its thickness and rersistency is availeble. For the town-
Ships in the southern half, datn are meager, and 2 general average
&sec on trickneuses in surround ing sreas was adopted, snd a low pter-
eenti7ea of recovery allovied because the extent and thickness of this
bed are not known.
This bed contains the greatest conl reserve within the county,
and renks second in production with a total of over 1,500,0CO tons
nanually.
Uprer Kittanning coal. Little information 2s to the extent and
thickness of this bed is available, except from its recognized out-
crop end development in a few localities, This bed is extremely
variable as to section and thickness, attaining srest heiekt in local
troughs or channels 200 to 500 yerds in width, and thinning 10) 2
inches or less at trough limits It is known as the "Pot Vein"
beceuse of this peculiarity, The Upper Kittenning bed in these troughs
is a cannel coal, with 24 inches and les3 of bituminous coal under the
cannel. Where available measurements shor sufficient thickness for
mining, the writer assumed the presence of smell workable areas con~
tiguous to the place of messurement. The ovantity of coral was com-
puted from the 2verrge thickness of the ‘hed in thet vicinity. A low
percentage of recovery has been adopted, owin2 to the extreme varia-
bility of this bed, and lack of knowleage as to its persistency and
extent.
The Upper Kittsenning cool as computed in this report is fifth in
size of reserve in the county, anc ranks third in production with 4
total of over 300,000 tons annually,
Lower thd as coal. A feir number of measurements of the
thickness of this coal sre available from its outcrop and development,
making possible a fash iy accurate computation of quantity.

Having calculated the quantity of cosl originally contained
Within the area of any bed and subtracted the quantity already mined
out, the writer dotermined from engineering experience the probable
percenta ee of each bed which could be recovercd in Gifferent locali-
ties. This varies from 60 to 90 per cent, depending on the thickness
and-character of the bed. The quantity of coal computed to be in any
bed, multiplied by the assumed percentage of recovery, less 15 per
cent for loss in mining, gives the estimated recoverable tonnage.
Coal Reserves.
The area of Armstrong County is 682.2 square miles,
The result of computing the conl reserves in Armstrong County
based on the latest maps, engineering data, and methods is shown in
the accompanying tabless.
-One table gives the estimated recoverable tonnage by beds end
townships. The tizurcs have been given 2s computed, It should
however be distinctly understood that wnile the acreage of énch ot
the beds has been : seourstely computea, the reliability of the avernge
thickness of the coals used in the computstion of tonnage decreases
for the beds in th order Following: Pittsburgh, Upper Freeport,
Lower Kittanning, lower Freeport, Upper xittanning, end Brookville.
Thus, while the figures for the Pittsburgh bed are conservative and
probably reliable, the figures for the Brookville coal may be much
too small or many "times too large.
