Dec 10, 2018· Traditionally a mechanical shearer cuts along the coal seam beneath a roof supported by hydraulic jacks, exposing miners to multiple risks on a daily basis. Increasing health, safety and productivity around the longwall mining process has been a long term industry goal.
Press releaseWhitehaven Coal's Narrabri North mine set new production records last year and subsequently ordered a second ® EL3000 Longwall Shearer and a second BSLPF6 Stage Loader for delivery in August this year.
Longwall system consists at least of armored face conveyor (AFC), a shearer, and roof support sections. The AFC is connected to outbound belt conveyor. The shearer cuts the product from coal seam face, in a series of passes along the AFC. The AFC delivers product to the belt conveyor connected.

Longwall coal mining is a full extraction underground mining method that involves the removal of coal in large blocks or panels using a mechanised shearer. The coal panel is typically 200350 m wide and can be up to five kilometres in length. The mechanical shearer is mounted on a shearer pan and rails
Mar 23, 2012· Purpose – Longwall mining is a special mining method with high productivity and smooth operation and the drum shearer is known as the most important component in longwall mines due to its direct role in the coal cutting and production process. Therefore, its reliability is important in keeping the mine production at a desired level.
