Picks undergo a high temperature variation during coal cutting by a continuous miner machine. Although it is difficult to measure the exact level of heat generated, an indication could be found in the course of this study. The melting and flowing of brazing (copperzinc based) over the CC part proves that the temperature might be raised to ...

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 ...
