Open-Air Mining of Coal by Electric Shovels

Multi-attribute fuzzy methodology for the selection of mining shovels

Mining shovels or excavators are basic equipment designed to dig and load material in surface mines. They are often considered the major material-handling equipment for high-production, low-cost operations (HPLC). The selection of an appropriate shovel for any HPLC operation is of critical importance because the overall production of the mine is measured in terms of material handled by a princi...

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...

Clean Hydrogen Energy and Electric Power Production with CO2 Capturing by Using Coal Gasification

Clean hydrogen is the major energy carrier for power production. The conversion of CO to CO2 and zero emission during hydrogen energy production causes high capital cost. It is a matter of prestige to optimize the process in order to make zero emission and cost effective production of clean hydrogen energy and electric power. In this era, coal gasification is th...
