An approach to map geotechnical uncertainty in Longwall

Geotechnical uncertainty in an underground longwall coal mining project can have serious implications on coal reserves estimation and classification, and needs to be assessed during the process of...

The Application of Geostatistics to Coal Quality Control

A geostatistical approach toward the coal quality control problem is presented. Two models, the prediction model and the conditional simulation model, have been developed for coal quality data from two large export coal mines in central Queensland, Australia.

Introduction to Longwall Mining and Subsidence ver2

In longwall mining, a panel of coal, typically around 150 to 300 metres wide, 1000 to 3500 metres long and 2 to 5 metres thick, is totally removed by longwall shearing machinery, which travels back and forth across the coalface.

The Application of Geostatistics to Coal Quality Control

The competitive coal market has required coal producers to put more effort into coal quality control. Successful quality control requires a good estimation of the in situ coal quality as well as a good estimation of the probable fluctuation of the in situ coal quality during production. Geostatistics offers a very promising way to meet...

Evaluation of the rockburst potential in longwall coal

Mar 24, 2017 Rockburst is a typical dynamic disaster in underground coal mines which its occurrences relate to the mechanical quality of coal seam and surrounding rock mass and also the condition of stress distribution. The main aim of this paper is to study the potential of rockburst in a longwall coal mine by using of passive seismic velocity tomography and image subtraction technique.
