From Introduction: "This compilation is the fourth and final in a series revising and expanding U.S. Bureau of Mines (USBM) Bulletin 605, "Thermodynamic Properties of 65 Elements-Their Oxides, Halides, Carbides, and Nitrides," by C. E. Wicks and F. E. Block (532)."

From Abstract: "During the next 5 years investigators examined a number of factors that have a bearing upon miners' ability to put on and use the apparatus in an emergency: the procedure being taught; availability and utilization of training models; opportunities to practice; hygiene; and on-the-job-training. This report presents an overview of that research."

Report issued by the Bureau of Mines over studies conducted on hazard control in talc mines. Methods of testing, and results of the study are discussed. This report includes tables, maps, illustrations, and photographs.

Report issued by the U.S. Bureau of Mines discussing mining accidents during equipment maintenance. As stated in the abstract, "this U.S. Bureau of Mines report identifies potential causes of slip-and-fall accidents occurring during surface mine equipment maintenance and describes the relative roles of direct worker behavior and machine design" (p. 1). This report includes tables, and illustrations.

From Abstract: "This bulletin describes the research and presents analytical results and evaluations over 5-3/4-year period from January 1981 to September 1986. Results show that iron casting compositions are charging with respect to a few tramp elements such as arsenic, cobalt, chromium, tin, zinc over the period. The data presented in this bulletin provide a means to ascertain whether the quality ferrous scrap is affecting casting quality."
