It combines operator assistance tools, automated sequences, advanced diagnostics, machine performance monitoring and more to help you optimize your longwall mining. Data is integrated and shared between the shearer and the roof supports, resulting in consistent and efficient cycle times and minimizing ...
A mining machine for mining along a mining face includes a longwall shearer, a product removal system for removing product cut by the longwall shearer, and a drive system for moving the longwall shearer along a rack extending along the mining face. The drive system including a housing coupled ...

Automation of longwall mining system Shearer-initiated shield advance (SISA) introduced in the 1980s was the first attempt in longwall system automation. A control computer, usually located at the headgate, communicated with the shearer and the electrohydraulic controls for the shields (Nelson, 2021...
we would be pulling belts or moving a shearer, miners would attempt to communicate with each other with their cap lamps. Today, the operator has hand-held radio and he’s driving a machine with the very best diesel engine. They say pull forward 10 ft and he can pull forward 10 ft.”...
In accordance with the coal mining process of the fully mechanized coal face, once the hydraulic support plate is not in place or not fully recovered during the working process, it may cause the movement interference between hydraulic support and shearer. Hence, it is necessary to find the ...
