Discrete Element Simulation of Conical Pick’s Coal Cutting

The shearer and conical pick, as the core device and main cutting tool, are widely used in mining engineering, and the basic physical phenomenon occurring during coal cutting process is fracturing and fragmentation of the coal under mechanical action of conical picks, of which the cutting parameters not only affect the cutting efficiency of

Investigation Into Coal Cutting Operation by Using Conical

During the cutting action of conical pick, it was found that as the depth of cut increases, specific energy decreases [8] The shape of conical pick remained sharp due to symmetrical wear during cutting [9] Conical tool bit provides better efficiency due to lowest specific energy for penetration [10]

Wear Assessment of Conical Pick used in Coal Cutting

Conical pick is a widely used tool for cutting coal in mines It has a cemented carbide tip inserted in a steel body Cemented carbide has been in use for many years for coal/rock cutting because it has the optimum combination of hardness, toughness and resistance against abrasive wear As coal/rock is a heterogeneous substance, the cutting tool has to undergo various obstructions at the time
