Tsoelo-pele ho Theknoloji ea ho Drilling ea Hydraulic le Metsi a DTH.

1. Melemo ea Hydraulic Rock Drills

① Khatello e Phahameng ea Hydraulic: Ka tloaelo ho tloha ho 10 ho isa ho 25 MPa, ka mokhoa o lebisang meeling e phahameng. Sena se phahame makhetlo a 'maloa ho isa ho a mangata ho feta khatello ea moea.

② Matla a Phahamiso a Phahameng: Ka kakaretso lipakeng tsa 5 ho isa ho 20 kW. Mefuta e meng, joalo ka COP4050 ea ATLAS le HL2000 ea TAMROCK, e fihla ho 40 kW, ha HL4000 e fihlella ho fihla ho 70 kW.

③ Lebelo la ho Cheka ka Potlako: Hangata ho finyella tekanyo ea ho phunya ea 1-3 m / min.

④ Ts'ebetso e Phahameng: Ho sebetsa hantle ha li-drill tsa majoe a hydraulic ka botsona ho ka fihla ho 50%, 'me lipompo tsa hydraulic li sebetsa hantle ho feta li-compressor tsa moea. Ka lebaka leo, tšebeliso ea matla ka kakaretso e phahame haholo ho feta ea lisebelisoa tsa ho phunya mafika a pneumatic.

2. Mathata a Hydraulic Rock Drills

① Tahlehelo ea Phetiso ea Matla: Kaha mochini oa ho phunya lefika o kaholimo ho molamu oa ho cheka, tahlehelo ea phetisetso ea matla e eketseha ka botebo bo boholo ba lesoba, e leng se bakang ho fokotseha ha lebelo la ho cheka.

② High Drill Rod Wear: Ha matla a li-drill rock a ntse a eketseha, khatello ea molamu oa boro le eona ea eketseha, e lebisang ho sekhahla se phahameng sa tšenyo. Leha mahlale a kang ho cheka casing ea Atlas Copco a thusa ho fokotsa khatello ea maikutlo, a eketsa litšenyehelo mme a hloleha ho rarolla bothata ka botlalo, ka hona a fokotsa matla a tsoang ho boro. Mohlala, ha matla a COP4050 a lekantsoe ho 40 kW, ke 30 kW feela e sebelisoang bakeng sa ho cheka mekoti e tebileng ho fokotsa khatello ea lisebelisoa.

③ Phapang ea Borehole: Lithupa tsa ho cheka li mamella matla le torque, tse lebisang ho kobeheng le ho kheloha, e leng ho fokotsang ho nepahala ha metsi.

3. Melemo eaDown-the-Hole (DTH)Diboro

① Ha ho Tahlehelo ea Phetiso ea Matla: Hamore e ama ka kotlolohocheka hanyane, ho felisa tlhokahalo ea phetisetso ea matla a matla ka molamu oa ho phunya, ho netefatsa lebelo le tsitsitseng la ho phunya ho sa tsotellehe botebo.

② Li-Boreholes tse otlolohileng: Molamu oa ho phunya o na le botsitso bo phahameng, ha o tlas'a tšusumetso ea matla, 'me o fetisetsa torque feela ka khatello e fokolang ea axial. Sena se thibela ho kobeha le ho senyeha, ho etsa bonnete ba hore ho na le likoti tse otlolohileng le tse boreleli. Li-drill tsa DTH li sebetsa betere ho sebopeho se robehileng, strata e sekametseng, kapa ho thatafala ha mafika.

③ Ho Tlosa Litšila ka Sebetsa: Mochini oa motlakase o sebetsa habeli joalo ka mochini o phopholetsang metsi, o hloekisa sekoti hantle le ho qoba ho cheka ho feta tekano.

④ Lerata le tlase: Kaha ts'usumetso e etsahala tlase ho borehole, lerata le tlase haholo ho fetalibono tsa hamore tse holimo.

⑤ Ts'ebeliso e Atolohileng: Ntle le libopeho tse bonolo haholo, liboro tsa DTH li sebetsa hantle mefuteng eohle ea majoe, ho feta lithupelo tsa majoe a holimo-limo ka bophara le botebo bo ka fihlellehang.

Ka lebaka la melemo ena, ho cheka ha DTH ho nkoa e le khetho e ntle ka ho fetisisa, 'me 90% ea likori tsa Brithani li sebelisa mokhoa ona.

4. Mathata a Pneumatic DTH Drills

① Khatello e tlase le Matla: Tšusumetso ea mantlha ea li-drill tsa DTH tsa moea ke khatello e tlase ea moea le matla a tsoang, a lebisang ho lebelo le liehang ho cheka. Leha tsoelo-pele e phahamisitse khatello ea moea ho 2.5 MPa, sena se ntse se le ka tlase ho khatello ea haeteroliki ea liboro tsa majoe. Ho feta moo, li-compressor tsa moea tse nang le khatello e phahameng li theko e boima, li hloka li-drive tse matla haholo, li hlahisa lerata le eketsehileng, 'me li lahleheloa ke ts'ebetso haholo libakeng tse phahameng.

② Tšebeliso e Ntle ea Matla a Matla: Li-drill tsa Pneumatic DTH li sebelisa matla a fetang a mararo ka mithara e 'ngoe ho feta li-drill tsa majoe a hydraulic.

5. Lisebelisoa tsa HydraulicDTH Lihamore

Ho kopanya melemo ea li-drill tsa majoe tsa haeteroliki (khatello e phahameng le katleho) le li-drill tsa DTH (boreholes tse otlolohileng), Hausherr oa Jeremane o ile a qapa "Rapid Hydraulic DTH Drill" mathoasong a bo-1990. Ka bobeli mokhoa oa eona oa ho potoloha le oa tšusumetso o tsamaisoa ka metsi. Hamore e na le mela e 'meli ea oli bakeng sa phepelo le ho khutlisa. Li-drill tse potlakileng li fumaneha ka li-diameter tse tharo: 90 mm, 115 mm, le 150 mm, tse loketseng likoti tse nang le bophara ba 100-125 mm, 127-156 mm, le 168-230 mm, ka ho latellana.

Teko ea papiso lipakeng tsa HBM80S pneumatic DTH drill ea Rapid le Hausherr e bonts'itse hore, bakeng sa bophara bo tšoanang ba borehole (125 mm) le botebo (36 m), Rapid e bonts'itse melemo e meholo ea moruo ka matla a tlase a enjene, tšebeliso ea mafura, le tšebeliso ea oli ea lubrication ea 0.46, 0.46, 0.46, le 0.46 ka tlhompho,

6. Likopo tsa lihamore tse tsamaisoang ke Metsi a Hydraulic

LKAB ea Sweden le setsi sa eona sa G-Drill ba ile ba qapa "Wassara Water-Powered DTH Hammer" mafelong a bo-1980. E sebelisa metsi a hloekisitsoeng a morafo e le sebaka se bohareng, e sebetsa ka khatello ea 18-20 MPa le litekanyetso tsa phallo ea 200-300 L / min. Ka lebelo le tloaelehileng la ho cheka la 850 mm/min, e feta lihamore tsa moea (hangata 320 mm/min).

Hamore ea Wassara e bonts'itse ts'ebetso e ikhethang, joalo ka ho fokotsa ho kheloha ha metsi ka halofo le ho eketsa tlhahiso ka 86% merafong ea LKAB. Likopo li kenyelletsa ho cheka ka tlas'a lefatše New York le ho chekoa ha mobu o chesang mobung oa Switzerland, moo ho ileng ha phethela borehole bo bolelele ba 599.8 m ka matsatsi a 5, ha ho bapisoa le libeke tse 3 tsa ho phunya rotary.

7. Papiso: Hydraulic Water-Powered vs. Hydraulic Fluid-Driven Hammers

Lihamore tse nang le Matla a Metsi: Sebelisa khatello ea metsi e tsitsitseng, ho finyella katleho e phahameng le lebelo la ho cheka, tse loketseng lits'ebetso tsa merafo.

Lihamore tse tsamaisoang ke Mokelikeli: Sebelisa khatello e matla ea metsi 'me ka kakaretso e lekanyelitsoe ho cheka jeoloji ka likhatello tse tlaase (0.5–4 MPa) le bokhoni (

8. Qetello

E tsamaisoa ka metsi le ka metsiDTH lihamorekopanya melemo ea li-drill hydraulic drill le lihamore tsa DTH tsa pneumatic, tse fanang ka tšebeliso e tlaase ea matla, lebelo la ho cheka ka potlako, le likoti tse otlolohileng. Mokhoa o kopaneng oa matla le ho phuphusela o etsa hore lihamore tse tsamaisoang ka metsi li be le tšepo bakeng sa nts'etsopele ea nako e tlang.
