Coal Burst (8 Reports)

Advances in Acoustic Logs to Predict the Stress Redistribution in Coal Strata as a Result of Degassing/Dewatering

C2702701/05/2021
Author: Hamid Roshan and Hossein Masoumi | University of New South Wales and Monash University

The aim of this project is to study the effect of fluid withdrawal on stress distribution in coal. Recent advances in acoustic log analysis and analytical models as well as field and laboratory data are used to evaluate the stress redistribution caused by fluid drainage from a borehole.

Coal Burst Monitoring Technology using Microseismicity – Microseismic Data Capturing and Documentation

Get Report
C2600601/03/2020
Author: Xun Luo, Joey Duan, Matt van de Werken | CSIRO

Coal burst is a violent collapse of the coal wall or roof in development, roadways and at the longwall face in underground coal mines. Because it occurs suddenly, with no or very little warning, coal burst is particularly dangerous to nearby mine personnel, mining equipment and infrastructure. ....  read more

 

Mechanics of Gas Related Coal Bursts in Mining

C2606003/02/2021
Author: Winton Gale | SCT Operations

Rock and coal fracturing is common about roadways, particularly under the influence of elevated stresses, either tectonic or related to mining abutment stress. Shear fracture is very common, however, it is very uncommon that the coal is propelled from the face or ribs as a result of fracture ....  read more

 

Modelling Of Dynamic Fracture Mechanisms For Improved Strata Control Design and Coal Burst Assessment

C2605401/01/2019
Author: Jan Nemcik, Gaetano Venticinque, Shivakuma Karekal | The University of Wollongong

The success of mining operations is heavily dependent upon controlling the fractured ground especially in coal mines where complex sedimentary strata exist. In nature, mechanisms of rock fracture are a dynamic phenomenon that up to now has not been fully understood nor computationally modelled ....  read more

 

Monitoring Stability of Roadway and the Longwall Face for Coal Burst Risk Management Using Distributed Fiber Optic Sensing Techniques

Get Report
C2704801/08/2020
Author: Xun Luo, Joey Duan, Ludovic Ricard, Matt van de Werken | CSIRO

In this project, the feasibility of using distributed optic fiber sensing (DOFS) technique was investigated for microseismic monitoring in coal mining. The investigation involved in theory study, laboratory tests and a mine site experiment.

Results from the laboratory experiments have ....  read more

 

New Outburst Risk Determination Measures Along With Data Gathering and Analysis for Coal Burst Assessment

Get Report
C2606224/05/2021
Author: Ian Gray, Jeff Wood, Tim Gibbons, Xiaoli Zhao | Sigra

Bursts are events that expel material at velocity at the time of ejection. This is usually coal but is sometimes rock. Unlike falls where the velocity is gained through gravitational acceleration, the sources of energy that drive the material outwards are either strain energy of the rock or ....  read more

 

Predict Stress State and Geotechnical Conditions Near Major Geological Structures Using Microseismic Technology and Distinct Element Modelling

C2605301/09/2019
Author: Baotang Shen, Bongani Dlamini, Lu Chen, Yi Duan, Xun Luo,Matt Van de Werken, Onur Vardar, Ismet Canbulat | CSIRO, The University of New South Wales

Stress state and geotechnical conditions often change significantly near major geological structures which is the cause of most major mine instabilities and/or safety hazards including coal burst, roof falls, water inrush, gas outburst etc. This project aimed to develop an integrated method of ....  read more

 

The Young’s Moduli, Poisson’s Ratios and Poroelastic Coefficients of Coals

C2606125/02/2019
Author: Ian Gray | Sigra

This report describes the measurement of coal (and rock) properties using core in laboratory tests where the axial and radial (confining) stresses and the fluid pressures are varied. The results derived from this work show quite different material behaviour to those generally considered to ....  read more
