Journal of Sustainable Mining
Methane plays a significant role in intensifying the greenhouse effect, possessing a global warming potential more than twenty times greater than that of CO2 when measured on a carbon-dioxide-equivalent basis. Hence, identifying efficient methods to mitigate methane emissions is crucial for safeguarding the environment, ensuring economic viability, and maintaining practicality. Globally, research initiatives are dedicated to crafting an effective catalyst system for methane oxidation, which involves developing catalysts, comprehending their characteristics, and determining the best way of bonding them to structural supports to enhance functionality. Notably, systems that incorporate metals from the non-noble d-block of the periodic table as …
Spatio-Temporal Changes In The Gravity And Post-Mining Seismic Activity In Abandoned Deep Coal Mine Kazimierz-Juliusz During Flooding, Andrzej Kotyrba, Łukasz Kortas, Sławomir Siwek
Spatio-Temporal Changes In The Gravity And Post-Mining Seismic Activity In Abandoned Deep Coal Mine Kazimierz-Juliusz During Flooding, Andrzej Kotyrba, Łukasz Kortas, Sławomir Siwek
Journal of Sustainable Mining
The flooding of an underground hard coal mine, resulting in the filling of post-mining voids (workings and goafs) and the repeated saturation of pore and interstitial spaces of the adjacent rock with water, change the mass and its distribution in the near-surface part of the earth’s crust. This process is slow and lasts many years. As a result, the local gravity field undergoes dynamic changes. It depends on the surface morphology and the density of geological strata, which is related to their water content. Changes in the local gravity field can be monitored by periodic gravity surveys performed in the …
Accident Analysis Of Mining Industry In The United States – A Retrospective Study For 36 Years, Elham Rahimi, Younes Shekarian, Naser Shekarian, Pedram Roghanchi
Accident Analysis Of Mining Industry In The United States – A Retrospective Study For 36 Years, Elham Rahimi, Younes Shekarian, Naser Shekarian, Pedram Roghanchi
Journal of Sustainable Mining
A retrospective study on accident analysis of the United States mines for 36 years was achieved using statistical analysis on the MSHA's accident databases between 1983 and 2018. A regression model of generalized estimation equation (GEE) was used for unbalanced panel data that provided 95,812 observations for 19,924 mine-ID-year in aggregate, coal, metal, and non-metal mines. The contributions of various parameters, including mine type, injured body part, days lost, age, and experience on the rate of accidents and injuries were investigated across the commodity types. The results showed coal miners in the East region are at a higher risk of …
Mine Warfare In The Russian And Soviet Navies, Jeffrey K. Bray
Mine Warfare In The Russian And Soviet Navies, Jeffrey K. Bray
Graduate Program in International Studies Theses & Dissertations
This thesis examines the development of technology, tactics, strategy, and organization of mine warfare in the Russian and Soviet navies from 1807 to the present. The author reviews the trials and tribulations of the development of naval mines and their employment within these two navies. This development has been primarily driven by the needs of war and advances of technology. In spite of occasional setbacks, the Russian and Soviet mine warfare forces continued to provide support to the overall naval and central policies of their respective governments. This support has often been during times of high tension and limited resources. …
