Coal drill picks are specialized tools used in conjunction with coal mining shearers. Primarily manufactured from tungsten carbide or high manganese steel, they boast unique geometries and strength to effectively penetrate and break up coal seams.
Cylindrical Picks
Cylindrical coal drill picks, characterized by their straight bodies and rounded tips, commonly find usage in various types of coal mines. In those mines where the coal layer is relatively thin, the cylindrical picks are good enough because they can work without the need for other additional implements. Still, their efficiency may decrease in harder rock formations.
Tapered Picks
Tapered coal drill picks also have a similar shape to cylindrical coal drill picks, but they become narrower toward the end, which allows for better precision mining. These picks are well-suited in areas with thick coal seams and hard rock layers that need to be meticulously mined. Thanks to tapered design, coal miners can easily navigate the layers and selectively extract valuable coal while minimizing wastage.
Button Picks
Button coal drill picks feature a unique design with a rounded button-shaped tip. This type coal drill pick distributes the mining load evenly and enhances the resistance to wear and impact. Button picks are often utilized in conjunction with other pick types to improve the overall efficiency and effectiveness of the coal mining process.
