14/9/2012Many of our longwall moves are simple walk-across moves. Sometimes, we have to set 100 to 150 shields. If a face has 240 shields, only setting 100 or 150 shields makes the move easier." They move the longwall with diesel-powered equipment. "It eliminates
22/8/2013Over the past several decades, coal companies have installed newly designed longwall equipment and increased longwall face productivity at coal mining operations. With the newly designed equipment, most major coal companies have strategically increased the width and length of longwall panels to reduce the amount of continuous miner development required to keep pace with the increased longwall
If you operate a longwall mining operation in Kentucky, Southern Indiana, West ia or Southeastern Ohio, Boyd is your one-stop heavy equipment headquarters. Our extensive underground mining equipment inventory includes a complete selection of longwall machinery from .
Workshop space and resources for equipment overhaul and repair must also be available to ensure the equipment can be turned around and sent back without delaying recommencement of the longwall. In most cases, equipment has to be recovered and re-installed in a particular order which places additional constraints on the process.

26/5/2017Longwall mining systems are capable of producing significant outputs from a single longwall face – 8 million tones per annum or more. There is a high capital cost for equipment, though probably not as high as first appears when compared to the number of
How mining companies can reduce the cost of purchasing equipment and improve the quality at the same time Theo Brechmann has 35 years of management experience; experience as a Design Engineer, Service Manager, Sales Director and CEO; and 20 years experience as a Sales Director for CIS countries at Eickhoff Bergbautechnik (until January 2018).
Because of these few pieces of earth moving equipment, the longwall mining system and the few support items required, this proposed demonstration projects inital capital cost are modest. The advancing trench that moves with the operating face

Two Distinct Set of Factors Drive Mining Cash Costs: The first set of factors relates to the actual costs of inputs: Skilled labor, mining materials, equipment, reagents, structural steel, and everything else that goes into running a mine. The second set of factors
150,000 tons per month by the installation of new mining equipment. His results are summarized in Table I. This analysis showed that the conventional drill and blast mining system was the least expensive (from an operating point of view) while longwall was the
17/2/2021Mastermyne maintains margins with new equipment and cost discipline INVESTMENT in operating equipment and a focus on cost management has helped underground contractor Mastermyne secure a 9% margin for the six months to December 2020 despite falling revenues due to reduced coal mining activity.
4/12/2018There are currently five active longwall operations in Turkey, four of which use longwall equipment. A Productive Alternative Longwall Top-Coal Caving isn't just an alternative mining technique; it can be the difference between a productive, profitable mine and an unsustainable operation.

Because of the high cost of longwall equipment in India, and the comparatively poor production results, Coal India has opted for a Risk-Gain type arrangement with its equipment suppliers. Under this arrangement, the equipment supplier has to give minimum production guarantees per face and operates the face for five years.
In high-performance longwall mining, the conveyor system must adjust quickly to carry huge loads and respond to load changes. CST drive systems provide intelligent features like no-load motor startup, AFC soft start and synchronized heavy-load startup to allow accurate load-sharing between up to three drive motors with excellent, extremely fast overload protection.
For many mining operations, renting offers the most convenient and cost-effective equipment acquisition solution. Renting provides a host of benefits, such as making the ideal match between machine and application to increase productivity and efficiency, reducing maintenance and repair costs, using the most up-to-date technology and gaining more financial flexibility.
Longwall mining range from hydraulic roof supports and automated plow systems to shearers, face conveyors and roof support carriers. CB MINING: High Production Demands A wide range of underground loaders and trucks to suit high production demands and lower cost per ton.
Longwall mining is one of the most efficient methods of coal extraction. It is also one of the most demanding. Gates combines world-class material science and expert engineering to manufacture products for the longwall mining industry that can take on the challenges of your longwall mining processes.
Longwall mining has traditionally been a manual process in which alignment of the face equipment was done with string lines. Technologies have been developed which automates several aspects of the longwall mining operation, including a system that aligns the face of the retreating longwall panel perpendicularly to the gate-roads.

LONGWALL MINING Overview In the method of secondary extraction known as longwall mining a relatively long mining face (typically in the range 100 to 300m but may be longer) is created by driving a roadway at right angles between two roadways that form the sides of the longwall block, with one rib of this new roadway forming the longwall face.
