Mining Machines for Comprehensive Mechanized Mining of Bauxite

Abstract The mining machine for bauxite is the key equipment mechanized of underground ore. machines shearing and loading ore have been studied in this paper from three aspects: determination technical parameters, in-situ tests, optimization, improvement. Mechanical physical parameters ore, such as high tensile strength, no-cleavage, abrasion properties, a great impact on machine. conventional conical picks which are widely used drums soft rock, coal mines, not suitable other high-abrasion rocks. chisel pick theoretically better choice. main faults during tests closely related to especially walking actuator traction part. So second-generation should be optimized selection types, linear speed, cutting depth picks, selecting wear-resistance material part designing more structure research results important theoretical significance design bauxite.
