Structural history of the southwestern corner of the Kaapvaal Craton and the adjacent Namaqua realm: new observations and a reappraisal [PDF]
, 1991 The rocks along the southwestern margin of the Kaapvaal Craton were deformed up to 7 times during the Early to Middle Proterozoic. The oldest deformation D1 is recorded in the N-S-trending Uitkoms cataclasite of pre-Makganyene age (>2.24 Ga) on the ...

VIBRATION EXPERIMENT OF COAL SHEARER CUTTING UNIT GEARBOX HOUSING IN OBLIQUE CUTTING
Jixie qiangdu, 2020 Oblique cutting is a working condition in fully mechanized mining whose main task is making it possible for long wall shearer to cut the coal seam,and it is a harsh working condition since the shearer is forced to be bent.

Research of Prediction of Gear Milling Force based on FEM Simulation of Oblique Cutting
Jixie chuandong, 2016 Considering the milling force calculated by using mechanical model or milling finite element simulation is time- consuming and tedious,a prediction method of milling force based on the finite element simulation of oblique cutting is proposed.
