Carbonizing Properties: Pocahontas Number 6, Davy Sewell, and Fire Creek Coals from West Virginia and Upper and Lower Kittanning and Upper and Lower Freeport Coals from Pennsylvania

From Forward: "The value of this survey of the carbonizing properties of American coals by a standard method lies in the comparability of the results on different coals. It must recognized that no standard laboratory method of carbonization, even on a large unit, can yield results that exactly duplicate those obtained in ovens and retorts. The commercial results vary with the type of oven or retort. Allowance must be made for such differences in interpreting the BM-AGA test results in terms of commercial plants."

Analyses of Coals in the United States with Descriptions of Mine and Field Samples Collected between July 1, 1904 and June 30, 1910 Part 2. Descriptions of Samples (open access)

Analyses of Coals in the United States with Descriptions of Mine and Field Samples Collected between July 1, 1904 and June 30, 1910 Part 2. Descriptions of Samples

From Introduction: "This volume contains the descriptions of the samples whose analyses are published in the preceding volume, Part I of this bulletin. The descriptions have been compiled from the notebooks of the persons who collected the samples, have been condensed from accounts given in published reports of the United States Geological Survey, or have furnished by the collection themselves. Inasmuch as the descriptions represent the work of many persons during a period of six years, and inasmuch as they were recorded under widely differing conditions, they necessarily vary in fullness detail."

Briquetting Tests of Lignite at Pittsburgh, Pennsylvania, 1908-9 : With a Chapter on Sulphite-Pitch Binder (open access)

Briquetting Tests of Lignite at Pittsburgh, Pennsylvania, 1908-9 : With a Chapter on Sulphite-Pitch Binder

From Results of Briquetting Tests: "The results of the briquetting investigations conducted by the Government are expected to prove of considerable value, not only to the Government itself as the owner of extensive lignite deposits and largest single purchaser of fuel, but also to the people living in the the regions where lignite is found. The problem assumes still larger proportions when one realizes that the development of manufacturing industries in those regions depends upon the ability to obtain a cheap and satisfactory fuel. Although the results presented in this bulletin are not conclusive, they warrant the continuation of the investigators as soon as funds can be available for the purpose."

Mine Flood Prevention and Control: Anthracite Region of Pennsylvania, Final Report of the Anthracite Flood-Prevention Project Engineers

Summary: "The engineering survey, summarized in this report, consisted of studies on acid mine water, underground-water pools, the "buried valley" of the Susquehanna River, inundated anthracite reserves, mine pumping plants, surface-water pools, seepage of surface water into mines, barrier pillars between mines, and geologic features of the region that included core drilling along alinement of the proposed Conowingo tunnel and to some extent along the proposed Marcus Hook alternate tunnel route. A comprehensive study was conducted to determine corrosion and erosion resistance of selected metals and alloys and to ascertain their suitability for components of pumps to be used in handling acid mine water."
