Essentially a plough is a large mass of steel, usually of a more or less triangular shape when viewed from the coal face or goaf sides, fitted with large "picks" (more like small agricultural plough blade tips) angled from the steel body towards the coal face.

Feb 7, 2025 · The coal plough does not have any rotating parts, it simply consists of a series of picks that are pulled along the coal face and scrape the coal of it. It is most suitable for coal seams that are realtively soft. A typical plough installation can be seen in the picture.

Feb 7, 2025 · Currently there are two types of longwall cutting machines: The plough, used mainly in Europe and to a lesser extent in the USA. The coal shearer is a more complex machine in comparison to the plough which is nothing more than a …

May 26, 2017 · Essentially a plough is a large mass of steel, usually of a more or less triangular shape when viewed from the coal face or goaf sides, fitted with large "picks" (more like small agricultural plough blade tips) angled from the steel body towards the coal face.

Plow systems extract segments of coal across the face of a coal seam during longwall mining procedures. They are used in lieu of a shearer on coal seam thickness less than 1.8 meters in height, and excavate coal in low and medium height coal seams.

What is Coal Plough:- A coal plough, also known as a coal cutter or shearer, is a mechanical mining device used in underground coal mining operations. It is designed to extract coal from a coal seam or face in a continuous process.

Sep 28, 2024 · Plough feeders are an integral part of coal handling plants, playing a crucial role in the initial stages of coal-based thermal power generation. These feeders are specifically designed for the extraction of loose materials, such as coal, from stockpiles, silos, and bottom discharge wagon systems.

The ploughing technology is what is known internationally as longwall mining, an extraction process for thin, seam-like (that is relatively thin and wide-area) deposits as found in Ibbenbüren. Main components are shield supports, armoured face conveyor as well as the extraction machine, the coal plough, which cuts the seam.

The coal plough cuts thin slices of coal from 100mm to 200mm and loads it onto an armored chain conveyor. It is used on longwall mining faces without props in seams from 0.6m to 2m thick. The plough has 4 or more teeth fixed to a base plate mounted on the conveyor chain.

This document summarizes different types of cutting machines used in underground coal mining. It focuses on coal ploughs and shearers. Coal ploughs cut a narrow strip of coal from the face using fixed picks, while shearers cut the full web width using rotating drums equipped with picks.
