Ndechipi chiri nani, chakatwasuka kana chidimbu chemuchinjikwa?
Zita rekuti "chibhorani chakaita muchinjiko" rinobva pakuti chibhorani chakaomeswa chakaita semuchinjiko chinonamatwa kusvika pamusoro pechibhorani. Iyo inozivikanwawo semuchinjika-yakaita bhatani bhatani bhiti, muchinjika-wakaita chibooreso chemuviri wakagadzirwa ne50Cr simbi uye inogadzirwa nekupisa extrusion, ine blade yepamusoro yakagadzirwa neyakaoma uye isingapfekere alloy. Kana kuri kuruka, vamwe vane shinda, asi vamwe havana; avo vasina shinda vanobatanidzwa zvakananga kune drill rod. Saizi dzakajairwa dzemabhiti ekubooresa akaumbwa anosanganisira φ28, φ32, φ34, φ36, φ38, uye φ40, ine saizi ye40 ndiyo inonyanya kushandiswa. Zviboorero zvakaumbwa nemuchinjikwa zvinonyanya kushandiswa mumigodhi, kuchera tunnel, uye mapurojekiti ekuvaka, zvichibvumira kuchera mumatombo kana marasha maumbirwo pasina kudzikisira kudhirowa kwakanaka kunyangwe uchigadzira machipisi mahombe. Kutsvaga kweYimei Machinery Manufacturing Co., Ltd. kunopa rumwe ruzivo.
Mamiriro ezviboorero ane chimiro chakachinjika anosanganisira nzira dzakareruka dzekugadzira, kushandiswa kuri nyore, mitengo yakaderera, uye kuchinjika kwakasimba kumamiriro ematombo. Nemaitiro akareruka ekugadzira, kugaya zviri nyore, uye kushanda kwakavimbika, mabhiti ekubooresa anochinjika zvakanyanya kune akasiyana dombo mamiriro. Iyo inowanzoshandiswa nechiedza chemukati chekupisa, magetsi, pneumatic, uye hydraulic rock drills kuchera makomba ane madhayamita ari pasi peD50mm mumhando dzakasiyana-siyana dzematombo. Nekuda kwekudhura kwadzo uye humwe hunhu, zvibooreso zvine muchinjika zvichiri kushandiswa zvakanyanya muindasitiri yezvicherwa yekuChina pakuchera makomba madiki nepakati nepakati.
