Based on the test principles of geological mechanics model and engineering geological and hydrogeological conditions of Nansi Lake, 12 geological mechanics model are established. By simulating the coal mining under the l...

BACKGROUND: Suicide is a public health problem worldwide. Estimates have indicated that over 1 million people commit suicide every year all over the world. Brazil has a moderate suicide death rate (4.1 per 100,000 inhabi...

This article looks at the politics of coal mining in East Kalimantan in Indonesia and La Guajira in Colombia. The focus is on government power and business interests. In a Marxian theoretical framework, the study questio...

Abstract Land subsidence induced by underground coal mining consistently leads to persistent ponding in coal-grain overlapping areas (COAs), substantially impairing agricultural productivity. However, amid stringent farm...

ObjectiveCurrently, the insufficient full-element digitization and the prevalence of “data silos” in fully mechanized mining faces (FMMF) result in poor cutting precision and operational instability of shearers under...

Coal mining community deputy Ivan Zoschenko remembers the injury that ended his football career, prepares for a former teammate's release from prison, and confronts a secret that has troubled his conscience.

This book seeks to offer a general approaching to breaches to human rights and the adverse effects on the environment resulting from the open economic policies implemented by the last Colombian Governments between 2002 a...

The coal mining areas spanning the Inner Mongolia-Shaanxi border represent both a quintessential ecologically vulnerable zone and a critically important coal production base in China. However, large-scale, high-intensity...

ObjectiveLimestone water hazards in coal seam floors represent one of the two primary categories of mine water hazards in China. Limestone aquifers are generally characterized by abundant static water reserves and consid...

Chattanooga has undergone a remarkable transformation from a heavily industrialized rail depot and one of the nation’s most polluted cities to the first designated National Park City in the United States of America...

Abstract With the intensifying depletion of coal resources, water hazard prevention and control for confined coal seam mining—characterized by ultra-thin aquicludes in both roof and floor adjacent to dual confined aqui...

During this time, the determination of the mine coordinates location done by the fieldman of PT. Kalimantan Earth Results was using a GPS locator. Found 27 points of coal mines and 18 coal ports spread across the souther...

Abstract Occupational Health and Safety (OHS), which holds substantial importance due to its profound human implications and far-reaching economic consequences, requires effective management to minimize workplace acciden...

Abstract In Australian open cut coal mines, floor disruption blasting is emerging as a promising technique for mitigating low wall failures by disturbing the continuity of shear planes within weak geological layers. Howe...

Abstract The uncontrolled floor heave in gob-side entry retaining is the serious problem of underground coal mining. This phenomenon has gravely restricted the application of pillarless mining that has been increasingly ...

This article first presents the theoretical and empirical foundations of “Station 2” of a didactic setting in which learners deal with sourcing operations and apply them to a text corpus on a topic created for this d...

Abstract Thick-hard roof fracturing presents a significant challenge for disaster prevention in longwall mining. This study investigates the 15,311 south working face and develops a mechanical model to analyze energy rel...
