Application of seismic monitoring in caving mines

, 2013
Comprehensive and reliable seismic analysis techniques can aid in achieving successful inference of rockmass behaviour in different stages of the caving process. This case study is based on field data from Telfer sublevel caving mine in Western Australia.

Measurement of the caved zone above a longwall panel, United Colliery

, 2022
This paper presents the results of a targeted goaf borehole program to define the edge of the Longwall 10 caved zone at United Colliery, Hunter Valley NSW. Longwall 10 is an isolated panel with a supercritical panel geometry.

Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

Journal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

Caving-induced subsidence behaviour of lift 1 at the Palabora Block Cave Mine

, 2016
The Palabora copper mine is a large, 32 000 t/d block cave operation located in the eastern half of Limpopo, South Africa’s northern-most province. Palabora Mining Company is currently developing a second lift (Lift 2) in addition to their existing block

Geochronological reconstruction of the Lateglacial deglaciation in the Arve Valley (Northern French Alps)

Journal of Quaternary Science, EarlyView.
ABSTRACT The timing and spatial patterns of glaciers retreat in the Northern French Alps during the Lateglacial (19.0–11.7 ka) remain debated, reflecting discrepancies among available chronological data sets. The complex interactions between major glaciers, such as the Rhône and Arve glaciers to the north and the Isère glacier to the south, represent a

Fracture Distribution Characteristics of Mining-induced Overburden in Thick Coal Seam and Pressure Relief Gas Extraction Technology

Meikuang Anquan, 2020
Aiming at the safety problem of high gas emission in 2303 fully mechanized caving face of Cuijiagou Coal Mine, the evolution law of “three zons” in goaf is studied by using physical similarity simulation and UDEC numerical simulation experiment on the ...

A GIS‐Based Approach to Modeling Carnivore Activity in the Pleistocene Site of Cova del Rinoceront (Iberian Peninsula)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT A significant methodological difficulty in the interpretation of Pleistocene zooarchaeological assemblages is the identification of taphonomic agents that modify and break bones. Carnivores, in particular, have been a main focus, as competition with carnivores may have affected carcass acquisition opportunities for humans in the past.

Study on overburden failure characteristics in deep thick loose seam and thick coal seam mining

Geomatics, Natural Hazards & Risk, 2020
In order to solve the related problems of roof collapse in deep thick loose seam, taking the actual geological conditions of 1302 working face of Zhaolou Coal Mine as the geological background. A mechanical calculation and analysis model for a deep thick

Rapid Prediction for Overburden Caving Zone of Underground Excavations

Geotechnics
Underground coal gasification (UCG) is an emerging energy technology that involves the in situ conversion of coal into syngas through controlled combustion within a subsurface excavation. The geomechanical processes associated with UCG can lead to significant overburden caving and surface subsidence, posing risks to surface infrastructure and ...

Balancing risk and reward—Perceptions of bats and their ecological role in Reunion island

People and Nature, EarlyView.
Abstract Context: Bats provide vital ecosystem services but can also generate disservices or sanitary concerns, particularly where human–bat interactions are frequent. Understanding public perceptions of bats is essential for effective conservation and risk communication.
