Blasting in Coal Mines •Modern mechanised coal mines use machines and longwall mining methods to cut solid coal and convey the broken coal out of underground workings. •Continuous mining equipment has escalated coal production and introduced more effective and efficient coal .
· Moving underground coal mining equipment from one section to another can be time consuming and costly. Traditionally, moving a large electrically powered piece of equipment, such as a continuous miner, feederbreaker or a roofbolter, required the power center to move along with the equipment.
The selection of the mobile equipment fleet for an underground mining operation is a vital part in determining the overall project net present value (NPV). As the underground mining industry is extremely capitalintensive, an analysis needs to be conducted on equipment fleet before any investments are made to ensure that the justifiion for purchase is quantified in advance.

Underground Longwall. Adapted to the mining challenges faced by our customers today, customized systems for longwall mining include hydraulic roof supports, highhorsepower shearers, automated plow systems and armored face conveyors with intelligent drive technology — controlled and supported by advanced longwall automation.
di erent equipment types have attributes that can interact in a complex way with respect to productivity. In surface mining appliions, the ESP addresses the selection of equipment to extract and haul mined material, including both waste and ore, over the lifetime of the mining pit.
methods of underground mining: roomandpillar and longwall mining. Selfadvancing, hydraulicallypowered supports temporarily hold up the roof while coal is extracted (Japan Coal Energy Center 2010). In this study, underground coal mining with the longwall shearer is examined. An overview of the coal mine is shown in Figure 1.

A feasibility prototype has been developed to provide support to decision makers in selecting mining equipment. The narrow domain of mobile underground coal mining equipment (for excavation and handling) was chosen for the study. The job of equipment selection is performed now by experts, who are both knowledgeable and experienced.

• Comprehensive core functionality for underground coal operations at both long and shortterm planning horizons: 3D mining reserve solids with integrated Gantt scheduling ... • Assess effect of equipment selection by defining multiple equipment types with different loss and dilution parameters.
EQUIPMENT SELECTION a) Armoured Face Conveyors (AFCs) Although frequently considered after supports and cutting machines, AFCs can be the ultimate limitation on face width. Given that geological, ventilation, financial and such issues would not limit a longwall width, it will almost certainly be the AFC which governs the final size.
