DTH rauj khawm khoom

Cov txheej txheem tho nrov tshaj plaws tam sim no yog DTH.

Ib qho kev xyaum hauv qab-qhov-qhov, raug hu ua DTH, feem ntau yog lub tshuab pneumatically tsav pob zeb lossis hauv av laum nyob rau hauv uas lub tshuab percussion tau muab tso rau tam sim tom qab lub laum me ntsis kom nws nqis mus rau hauv lub qhov xyaum nrog rauj me ntsis. Lub qhov me ntsis tau txais cov cua compressed nrog rau qhov yuav tsum tau pub kev nom kev tswv thiab kev sib hloov los ntawm cov kav dej laum.

Cov txiaj ntsig zoo xws li qhov zoo tshaj qhov ncaj, qhov zoo tshaj plaws ntxuav, du, txawm cov phab ntsa rau cov khoom tawg yooj yim, qhov tob qhov drilling peev xwm, thiab lub zog hloov pauv tau ua tiav cov txheej txheem drilling.

Nws yog qhov yooj yim los ua kom pom qhov loj tshaj plaws ntawm qhov chaw txua txiag zeb lossis qhib qhov mine siv cov txheej txheem DTH. Tsis tas li ntawd, DTH yog qhov zoo tshaj plaws rau kev siv ntau yam ntxiv, suav nrog kev drilling rau cov dej hauv dej, kev tshawb fawb, cov hauv paus, kev thauj mus los, thiab qhov chaw qhib hauv av.

Drilling cov cuab yeej rau hauv lub qhov, suav nrog laum yeeb nkab, ntsis, thiab rauj. Lub hauv paus rauj me ntsis yog ua los ntawm cov hlau thiab tungsten carbide nyees khawm, thiab nws nto yog compressed thaum lub sij hawm tshwj xeeb thermal txheej txheem kom nws toughness thiab hnav tsis kam.
