Determination of Coal Seams Depth of Erosion with Respect to the Remnants of a Key Bed in Kerman Coal Field, Iran

As a tool for exploration of concealed coal seams by modern techniques, determination of the depth of erosion of coal seams with reference to the surface of angular unconformity underlying the remnants of a key bed is conducted for the first time in coal mines of Kerman region. The angular unconformity surface (the initial surface exposure of coal seams) separates the coal seams of Jurassic age...

NUCLEAR BOREHOLE LOGGING TECHNIQUES DEVELOPED BY CSIRO-EXPLORATION AND MINING FOR IN SITU EVALUATION OF COAL AND MINERAL DEPOSITS M. BORSARU and J. CHARBUCINSKI

A range of nuclear spectrometric techniques for quantitative borehole logging and surface quantitative analysis for the coal and metalliferous mining industries. The paper reviews the latest developments of this technology.

Determination of a suitable extraction equipment in mechanized longwall mining in steeply inclined coal seams using fuzzy analytical hierarchy method (Case study: Hamkar coal mine, Iran)

The longwall mining method is one of the most applied methods in extracting low-inclined to high-inclined coal seams. Selection of the most suitable extraction equipment is very important in the economical, safety, and productivity aspects of mining operations. There are a lot of parameters affecting the selection of an extraction equipment in mechanized longwall mining in steeply inclined coal...

Fundamentals of 3D modelling and resource estimation in coal mining

The prerequisite of maintaining an efficient and safe mining operation is the proper design of a mine by considering all aspects. The first step in a coal mine design is a realistic geometrical modelling of the coal seam(s). The structural features such as faults and folding must be reliably implemented in 3D seam models. Upon having a consistent seam model, the attributes such as calorific val...
