Mechanisms of Roadway Instability and Coupled Control Technology for Working Face Passing Through Fault Zones

Energy Science &Engineering, Volume 14, Issue 9, Page 4470-4485, September 2026.
This study mainly explores the instability characteristics of roadways near faults in the working face. Taking the 51104 transportation roadway of the 51104 working face in Shengxin Coal Mine as the main research object, through theoretical analysis, borehole inspection, numerical simulation and on‐site mine pressure observation, the instability ...

Influence of Surface Processes on Intrarift Fault Displacement: 1.38 Million Years of Fault Slip Behavior in the Lake Malawi (Nyasa) Rift

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Surface processes, including hydroclimate variations, affect crustal deformation and fault behavior. These controls are especially important for intrarift faults in continental rift systems, which accommodate substantial strain while experiencing large hydrological load variations beneath rift lakes.

BASIC STUDY ON THE FLOOR HEAVE AND ITS COUNTERMEASURES OF THE MOUNTAIN TUNNELS

Journal of Japan Society of Civil Engineers, Ser. F1 (Tunnel Engineering), 2015
Some mountain tunnels suffer from floor heave after completion, and some of them require countermeasures. This phenomenon occurs if there are no big deformation during construction, therefore, under existing circumstances, based on preliminary survey and condition of excavation, to predict the floor heave deformation after completion is difficult.

Anatomy of Interannual to Decadal Sea Level Changes in the GECCO3 Ocean Synthesis

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The GECCO3 synthesis is used to infer a dynamically consistent decomposition of sea level changes (variability and trends) on interannual to decadal time scales. Over most parts of the global ocean equatorward of 60° latitude, sea level variability and trends can be explained almost completely by the upper ocean (above 2,000 m) steric ...

Deformation and Failure Characteristics and Control Technology of Roadway Surrounding Rock in Deep Coal Mines

Geofluids, 2020
With the increase in mining depth, the problem of the floor heave of a roadway is becoming increasingly prominent. Solving this problem for a deep high-stress roadway is the key to ensure safe supply and utilization of coal resources in China. This study

‘The White Hordes From the West’: Race and Refuge in Australian Media Commentary About White Rhodesians During Zimbabwe's Decolonisation

Australian Journal of Politics &History, Volume 72, Issue 3, Page 449-462, September 2026.
ABSTRACT This article explores Australian media commentary on white Rhodesians migrating to Australia, focusing on the period of Malcolm Fraser's prime ministership (1975–1983). The main argument is that the Australian media debates about whether to classify white Rhodesians as ‘migrants’ or ‘refugees’ were not merely semantic but reflected a deeper ...

On 3‐MMC: A Cathinone I Have Come to Know and Love

Anthropology of Consciousness, Volume 37, Issue 2, Fall 2026.
ABSTRACT This article attempts to complicate the mythology of a compound in a state of becoming. I will trace lightly its origins as a cultural disruptor and how I am implicated in this imperative. Introducing you to 3‐MMC will require multiple modes of storytelling and taking of liberties, drawing on literature reviews, practice‐based research, prose,
