Marketing of coal mining equipment. Evaluation of present techniques: suggestions to aid commercialization. Final report

Description: This report is an examination of the equipment preferences and decision-making methodology of the coal industry. The prime purpose is to indicate directions in which equipment research might proceed and also to indicate methods by which investment in new, more productive mining equipment could be encouraged. In addition to this, an investigation of the research and development decisions of major mining equipment manufacturers was conducted. The findings can best be condensed into three categori… more

Radon-222 emissions in ventilation air exhausted from underground uranium mines

Description: The /sup 222/Rn concentration in exhaust air is being measured at underground uranium mines in the Grants, New Mexico area. The objectives of the work are to determine relationships between U/sub 3/O/sub 8/ production and the mine characteristics and practices relative to /sup 222/Rn emission. Concentrations in the vent air from two mines ranged from 80 nCi/m/sup 3/ to 3800 nCi/m/sup 3/ during a month of observations. Diurnal radon emission patterns were seen for each mine which were inversely … more

Flexible roof drill for low coal. Volume 2. Phase III and Phase IV

Description: Design specifications were developed for a flexible drilling and bolting system. The system configuration is based on the use of the Galis dual-boom roof drill as a vehicle for the drilling/bolting system. The WSU Flex-drill drivehead is mounted on the Galis drill boom and the Galis parts are modified to accommodate the revised system. The flexible drillhead supports a bolt bender/inserter designed by Bendix Corporation and is integrated into the system operation. A supplemental bolt thruster w… more

Toxic Hazards of Underground Excavation

Description: Inadvertent intrusion into natural or man-made toxic or hazardous material deposits as a consequence of activities such as mining, excavation or tunnelling has resulted in numerous deaths and injuries in this country. This study is a preliminary investigation to identify and document instances of such fatal or injurious intrusion. An objective is to provide useful insights and information related to potential hazards due to future intrusion into underground radioactive-waste-disposal facilities… more

Descriptions of reference LWR facilities for analysis of nuclear fuel cycles

Description: To contribute to the Department of Energy's identification of needs for improved environmental controls in nuclear fuel cycles, a study was made of a light water reactor system. A reference LWR fuel cycle was defined, and each step in this cycle was characterized by facility description and mainline and effluent treatment process performance. The reference fuel cycle uses fresh uranium in light water reactors. Final treatment and ultimate disposition of waste from the fuel cycle steps were not … more

High-volume, high-value usage of flue gas desulfurization (FGD) by- products in underground mines: Phase 1, Laboratory investigations. Quarterly report, April--June 1995

Description: The kinetics study which is investigating hydration reactions of the ADM by-product (Subtask 2.2) was continued this quarter. This study further aided in gaining information on mineral precipitation and dissolution reactions during hydration of the ADM materials. The information is of importance for a comprehensive understanding of the factors that control strength and long-term stability during aging of FGD materials. The decision was made by Addington, Inc., DOE, and the University of Kentuck… more
