From Introduction and Summary: "Reports from operating companies showed that 25,715 men worked at coke ovens in 1951, about 6 percent more than were employed in 1950 and, except in 1943, the largest work force since 1930, when 28,139 men were employed. The work time for all employees was 70,190,493 man-hours. The returns indicated an average of 344 work days per man as compared with 341 days in the previous year. Accidents at the ovens resulted in the death of 10 and injury to 768 workers, both of these figures representing fewer injuries than in 1950."

From Introduction and Summary: "This report is essentially text on oil-reservoir mechanics and the problem of locating and drilling oil wells."

From Introduction: "The purpose of this report is to analyze the coal-mine bumps that have occurred on pillar lines during the past 25 years in the hope that the analyses and the conclusions drawn will aid mining engineers and other mine officials in improving layouts and face mining methods in mines where bumps reasonably may be expected to occur."

Introduction; "The purpose of this paper is to present in collected and sequential form such a list of the coals that have been studied in the carbonization-section labatories of the Bureau of Mines for their carbonizing properties and yields of coke and coal chemicals."

From Introduction: "This bulletin presents a general description of methods that have been proposed or tried for production of sponge iron and direct iron."

From Scope of Report: "The report covers the following: (a) A brief description of the proposed Conowingo tunnel system, which will drain the anthracite mines of Pennsylvania into the Susquehanna River at Conowingo. Md.; (b) economic development of the Northern field and the improvements desired; (c) geology and hydrology of the Northern field; (d) the basic problem, plans, and costs of Project No.1 (Lackawanna) ; (e) economic analysis and justification of the project; and (f) final recommendations, including financing and cooperation of local interests."

From Introduction: "Data on the injury experience at coal mines in the United States in this bulletin are presented in two section sections. General and detailed data on the 1950 safety record at bituminous-coal, lignite, and Pennsylvania anthracite mines, separately an combined are included in the first section. The second section contains certain historical injury statistics at all coal mines from the earliest available data through 1950."

From Introduction: "The present publication includes an appendix listening seven satisfactory fuels available for use in permissible flame safety lamps and shows where the fuels are available. This publication also includes an appendix listening manufactures of flame-resistant trailing cables, with the corresponding symbol that must be used by these manufactures in marketing trailing cables that have passed the test for flame resistance contained in Schedule 2E."

From Introduction: "This bulletin purposes to collect and compile, in readily usable form, heat and free-energy-of-formation data for inorganic oxides. Such data are used in evaluating heat balances in metallurgical processes, in appraising possible improvements in existing metal extractive methods, and as a guide in the search for better methods of producing metals of recent or possible future commercial interest."

Report displays a bibliography of numerous literature affirms air pollution has been a problem through the centuries.

From Introduction: "The purpose of this report is to furnish factual data on barrier pillars that enter into the water problem of the Wyoming Basin; these data will, in turn, be helpful in solving the anthracite-mine-water problem of the Northern field."

Scope of Report: "This report summarizes the engineering study conducted during 1953 by engineers of the Federal Bureau of Mines on seepage of surface water into mine workings underlying the Southern field drainage area."
