Heavy rockbursts due to longwall mining near protective pillars: A case study

International Journal of Mining Science and Technology, 2018
Rockburst represents a very dangerous phenomenon in deep underground mining in unfavourable conditions such as great depth, high horizontal stress, proximity of important tectonic structures, and unmined pillars. The case study describes a recorded heavy

Microplate Tectonics Through Earth History and Across Solid Multispheres

Geological Society of China Bulletin, EarlyView.
The evolution of tectonic microplates throughout Earth´s history as well as the transitions between microplates across different solid spheres offers a novel approach to expanding the traditional plate tectonics theory. ABSTRACT The evolution of tectonic microplates throughout Earth's history as well as the transitions between microplates across ...

Legitimacy in contested issue fields: How type‐based validity cues, cue congruence, and personal values shape propriety

European Management Review, EarlyView.
Abstract Contested business practices are often difficult to evaluate because they send multiple, often conflicting signals about their appropriateness. Some cues may suggest that a practice is useful, legal, or widely accepted, whereas others may suggest that it is risky, harmful, or socially opposed.

Contestation Between the State, Oil and Fishers in Trinidad and Tobago: (Re)producing ‘Edge’ Populations on the Post‐Plantation Extraction Frontier

Journal of Agrarian Change, EarlyView.
ABSTRACT Successive waves of extraction in the Caribbean—from plantation monocultures to oil and gas—have reshaped overlapping agrarian, coastal and marine environments, undermining the socio‐ecological foundations of small‐scale fisher livelihoods and generating ongoing conflict between the state, energy sector and fishing communities. Yet despite the

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

Seismicity induced by longwall coal mining at the Thoresby Colliery, Nottinghamshire, U.K. [PDF]

, 2017
The United Kingdom has a long history of deep coal mining, and numerous cases of mining-induced seismicity have been recorded over the past 50 yr. In this study, we examine seismicity induced by longwall mining at one of the United Kingdom’s last deep ...

The effect of selected rockburst prevention measures on seismic activity – Case study from the Rudna copper mine

Journal of Sustainable Mining, 2018
In order to face threats from mining tremors a number of organizational and technical prevention methods are applied in underground mines. Unfortunately, most of these methods are based on the experience of crew and there is uncertainty whether in ...

High Resolution Focal Mechanisms and Stress Field Orientation in Southern Italy From Short‐Term Dense Arrays

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Understanding fault geometry and mechanics is key to interpreting the seismotectonic setting of a region. We analyze data from a 1‐year dense seismic array deployment in Southern Italy to infer focal mechanisms and stress field from low‐magnitude earthquakes using machine‐learning techniques.

Seismicity induced by hard coal mining in the vicinity of faults

E3S Web of Conferences, 2018
An inherent feature of Polish collieries within the Upper Silesia Coal Basin is the high level of mining induced seismicity, resulting in elevated rockburst hazard levels.
