Hauv kev siv tswv yim, mining machinery qhov chaw ua rau muaj teeb meem hauv qab no:
(1) Hnav thiab tsim kua muag: Vim muaj kev sib txhuam ntev nrog cov ore, qhov chaw ntawm crushing thiab tshuaj ntsuam xyuas qhov chaw raug cuam tshuam rau kev hnav, ua rau kev ua haujlwm tsis zoo.
(2) Fracture: Vim muaj kev cuam tshuam cov khoom thauj lossis cov khoom siv qaug zog, qee qhov chaw yuav ua rau tawg lossis tawg.
(3) Corrosion: Nyob rau hauv cov av noo los yog tshuaj lom neeg corrosive ib puag ncig, hlau qhov chaw yog nquag xeb thiab corrosion.
(4) Lub foob tsis ua haujlwm: Kev laus cov ntsaws ruaj ruaj hauv cov khoom siv hydraulic tuaj yeem ua rau cov roj xau, cuam tshuam rau kev ua haujlwm ntawm cov khoom siv.
