Mavhiri epasi pevhu ndiwo akasarudzika marudzi emavhiri akagadzirirwa kushandiswa mumigodhi yepasi pevhu uye tunneling mashandiro. Mavhiri aya akagadzirwa kuti akwanise kumira nemamiriro ezvinhu akaoma uye akaoma anowanikwa munzvimbo dzepasi pevhu, kusanganisira nzvimbo dzakashata, zvinhu zvinokuvadza, uye nzvimbo dzakavharirwa. Kune marudzi akasiyana-siyana emavhiri epasi pevhu, rimwe nerimwe richishandisa chinangwa chaicho mukuchera uye kuita tunneling. Mimwe mienzaniso yakajairika inosanganisira: 1. **Mining Truck Wheels**: Rori dzinochera pasi pevhu imotokari dzinorema dzinoshandiswa kutakura zvinhu nezvicherwa mumigodhi yepasi. Mavhiri emarori aya akagadzirwa kuti atakure mitoro inorema, kuti akwanise kutakura zvinhu zvisina kuenzana, uye kuramba kusakara nekubvaruka kubva kune zvinokuzvuka. 2. **Mine Cart Wheels**: Ngoro dzemigodhi ingoro duku, dzine mavhiri dzinoshandiswa kutakura zvinhu mukati memigero yemugodhi. Mavhiri engoro idzi akasimba uye akasimba, achiita kuti akwanise kufamba nenzira nhete uye dzisina kuenzana. 3. **Tunnel Boring Machine (TBM) Mavhiri**: Michina inoboora mugero michina mikuru inoshandiswa kuchera tunnel mumigodhi uye mapurojekiti ekuvaka. Mavhiri ari pamichina iyi akanyatsogadzirwa kuti akwanise kubata masimba makuru anosanganisirwa pakuita tunneling uye kuti arambe akasimba padombo nevhu zvaanosangana nazvo. 4. **Conveyor Belt Wheels**: Mukushanda kwemigodhi yepasi pevhu, mabhandi ekutakura anoshandiswa kutakura zvinhu pamadaro marefu. Mavhiri ari paconveyor masisitimu akagadzirwa kuti atsigire mitoro inorema uye anopa mafambiro akatsetseka achitevedza nzira dzekutakura. 5. **Locomotive Wheels**: Zvitima zvepasi pevhu zvinoshandiswa kutakura vashandi uye zvinhu mukati memugodhi. Mavhiri ari pazvitima izvi akagadzirwa kuti ashande panzira nhete munzvimbo dzakamanikana. Mavhiri epasi pevhu anowanzo gadzirwa kubva kune-yakakwirira-simba zvinhu, senge simbi kana alloy, kutsungirira mamiriro anodiwa pasi pevhu. Ivo vanogona zvakare kuve vakashongedzerwa nekuwedzera maficha senge akasimbiswa matreads, akakosha machira, kana kupisa kurapwa kuti vawedzere kusimba nekuita kwavo. Tichifunga nezvemamiriro ezvinhu akaoma uye kufunga nezvekuchengetedza mumigodhi yepasi pevhu uye tunneling, dhizaini uye kuvakwa kwemavhiri epasi pevhu kwakakosha kuti kuve nechokwadi chekushanda kwakanaka uye kwakachengeteka mumaindasitiri aya.
