Research on the relationship between coal burst tendency and rockburst risk of coal seam

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2020
The burst tendency and the risk of rock burst are of great significance in the research of coal mine, which is the basis for the prediction and prevention of rock burst.

Extending Present Coal Reserves with Self-Bursting Coal Pellets: ABSTRACT

AAPG Bulletin, 1983
A new scheme is proposed which would extend our present reserves of coal by making use of what is now a waste product. End_Page 519------------------------------ Studies show that up to 25% of the volume of coal is lost as fine coal particles in the coal mining and handling process.

Coal mass rating with regards to outburst and coal burst

Outbursts and coal bursts pose significant risks to underground coal mine workers. The burst propensity of a coal seam is represented by the three factors of the burst triangle: coal, energy, and isotropic mass. The most critical factor was determined to be isotropic mass controlling the storage potential and release rate of burst energy.

Determination of the possibility of rock burst in a coal seam

Journal of Applied and Industrial Mathematics, 2017
Summary: The article presents an algorithm for computing a quantity that serves as a criterion for the possibility of rock burst in a coal seam. We propose to study this quantity in two steps: in the first step, an inverse problem is solved to find the necessary quantities; while in the second step, we solve a boundary value problem for a biharmonic ...

Determination of coal burst risk zones using CT scanning of coal microstructure

The Australian Coal Association Research Program (ACARP) sponsored a research project (C28012 Extension) investigating the role of microfracture propagation contributing to the mechanism of gas related coal bursts. The research project used Computed Tomography (CT) scanning to identify microfracture networks and the spatial and statistic relationship ...
