Matatu Matatu ERombo Drilling

Pane nzira nhatu dzekuchera matombo - Rotary drilling, DTH (pasi pegomba) kuchera uye Kuboora sando yepamusoro. Idzi nzira nhatu dzakakodzera kune akasiyana migodhi uye matsime ekuchera, uye sarudzo isiriyo inokonzeresa kurasikirwa kukuru.

Chokutanga pane zvose, tinofanira kuziva misimboti yekushanda kwavo.

Rotary drilling

Mukudhirowa kwekutenderera, rig inopa yakakwana shaft pressure uye rotary torque. Iyo bhiti inoboorera nekutenderera padombo panguva imwe chete, iyo inoshandisa zvese static uye dynamic impact pressure padombo. Mabhiti anotenderera uye achikuya pasi pegomba kuita kuti dombo rityoke. Mhepo yakadzvinyirirwa pasi peimwe dzvinyiriro uye mwero wekuyerera unopfapfaidzwa kubva pamuromo nemukati mepombi yekuboorera, kuita kuti slag irambe ichivhuvhuta kubva pasi pegomba pamwe nenzvimbo yeannular pakati pepombi yekuchera uye madziro ese kusvika kunze.

Pasi pegomba (DTH) kuchera

Kuboora pasi-paburi ndiko kutyaira sando iyo iri kuseri kwechibhorani nemhepo yakatsikirirwa kuburikidza nepombi yekuboorera. Iyo piston inorova bhiti yakananga, ukuwo sando yekunze silinda inopa yakatwasuka uye yakagadzikana kutungamira kwechibhorani. Izvi zvinoita kuti simba resimba rirege kurasika mumajoini uye richibvumira kudhirowa kwakadzika kwepercussion.

Uyezve, simba rinokonzera rinoshanda padombo riri pasi pegomba, iro rinonyanya kushanda, uye rakananga kupfuura dzimwe nzira dzekushanda kwekuchera.

Uye DTH inonyanya kuenderana negomba hombe rekuchera dombo rakaomarara, yakakosha pakuoma kwedombo pamusoro pe200Mpa. Zvisinei, kune dombo riri pasi pe200 MPa, haizongorambidzi simba chete, asiwo mukuchera kwakadzika, uye kupfeka kwakakomba kune chibooreso. Imhaka yekuti nepo piston yesando ichirova, dombo rakapfava harigone kutora mabatiro acho zvachose, izvo zvinoderedza zvakanyanya kushanda kwekuchera uye slagging.

Pamusoro Hammer Drilling

Simba rekurovera repamusoro nyundo yekuchera inogadzirwa nepiston yepombi mune hydraulic drilling rig, inotapurirwa kune dhill bit kuburikidza neshank adapta uye pombi yekuchera.

Uyu ndiwo mutsauko uripo pakati peDTH drilling. Zvichakadaro, iyo percussion system inotyaira iyo yekuchera system kutenderera. Kana iyo stress wave yasvika pa drill bit, simba racho rinoendeswa kudombo nenzira yekupinza zvishoma. Iko kusanganiswa kweaya mabasa kunogonesa kuchera maburi mudombo rakaoma, uye air compressor inongoita kubvisa guruva uye slagging mukuchera nyundo yepamusoro.

Impact simba rinowanziridzwa nekukanganisa frequency pamwe chete rinogadzira iyo percussive kubuda kweiyo drifter. Zvisinei, kazhinji, kuchera nyundo yepamusoro inoshandiswa pagomba dhayamita inokwana 127mm, uye kudzika kwegomba isingasviki 20M, iyo mukushanda kwepamusoro.
