Iyo Yekupedzisira Nhungamiro Yekusarudza Yekurudyi Yekuchera Turusi: Tricone Bits vs. DTH Sando

Atrione zvishomachibooreso chinotenderera chinowanzoshandiswa pakuchera matombo. Iwo akagadzirwa aine misoro mitatu yakakoniwa inotenderera nekukuya padombo, ichiita kuti ive yakanaka kune yakaoma maumbirwo akadai seraimu, shale, uye granite. Tricone drill bits inouya mumhando dzakasiyana dzemagadzirirwo, anosanganisira akavharirwa uye akavhurika mabhero, uye anoshandiswa mukuchera oiri negasi pamwe nekuchera matsime emvura.

Asando yepasi-paburi, nerumwe rutivi, mudziyo wokuboora unoshandiswa ne-down-the-hole drill bit kuchera makomba pasi. Sando dzepasi-paburi dzinoshanda nekushandisa high air pressure kudhiraivha bhiti mudombo, zvichiita kuti rive rakanakira matombo akaoma uye anopwanya. Kune marudzi maviri makuru e-down-the-hole impactors: echinyakare pasi-the-gomba impactors, inoshandiswa kune yakaderera mhepo, uye high-pressure.down-the-hole impactors, inoshandiswa kumanikidziro emhepo yakakwirira yekukurumidza, kuchera zvakanyanya.

Saka, iwe unosarudza sei pakati petricone drill bit uye pasi-the-gomba impactor yepurojekiti yako yekuchera? Sarudzo inozoenderana neiyo chaiyo geology yenzvimbo yekuchera uye inodiwa yekudhirowa kumhanya uye kugona. Tri-cone drill bits anonyatsokodzera kuchera mumatombo akaomarara, nepo DTH sando dzichinyanya kushanda muabrasive uye akatsemuka matombo maumbirwo.

Kana iwe uchitsvaga kuita kwakasiyana-siyana uye kugona kuchera makomba mumhando dzakasiyana dzematombo, chibooreso chetricone chingave sarudzo yako yakanaka. Zvisinei, kana iwe uchida kuboora nekukasira uye nemazvo mumaumbirwo akaoma uye abrasive, high-pressure down-the-hole sando uye drill bit musanganiswa ingava sarudzo iri nani.

Muchidimbu,tri-cone drill bitsuye down-the-hole impactors vane zvawo zvakanakira uye mashandisirwo muindasitiri yekuchera. Nekunzwisisa mutsauko uripo pakati pezvishandiso zviviri izvi uye uchifunga nezve chaiyo geology yenzvimbo yako yekuchera, unogona kuita sarudzo ine ruzivo nezve chishandiso chakanakira purojekiti yako. Kunyangwe ukasarudza tri-cone drill bit kana down-the-hole sando, kuva nematurusi ekuchera akakodzera kunogona kuita kuti chirongwa chako chekuchera chibudirire.
