Features And Preparation Of Tungsten Carbide Mining Tool

Tungsten Carbide Mining Tool Features 1.1 Wear resistance of WC alloy . The shearer of the shearer is in direct contact with the coal seam during the working process. The abrasive wear characteristics of the shearer are closely related to the coal seam structure and hardness. The hardness of the coal is low, generally 100 to 420 HV, but the coal often contains different hardness. Impurities

Coal mining Wikipedia

Coal mining is the process of extracting coal from the ground. Continuous mining utilizes a Continuous Miner Machine with a large rotating steel drum equipped with tungsten carbide picks that scrape coal from the seam. Operating in a "room and pillar" (also known as "bord and pillar") system—where the mine is divided into a series of 20-to-30-foot (5–10 m) "rooms" or work areas cut
