Ukuqhubela phambili kwi-Hydraulic kunye ne-Manzi-Powered DTH Drilling Technology.

1. Izinto eziluncedo kwi-Hydraulic Rock Drills

① Uxinzelelo oluphezulu lweHydraulic: Ngokuqhelekileyo ukusuka kwi-10 ukuya kwi-25 MPa, kunye nentsingiselo ukuya kwimida ephezulu. Oku kuphindwe kaninzi ukuya kwishumi lamaxesha aphezulu kunoxinzelelo lwe-pneumatic.

② Amandla eZiphumo eziphezulu: Ngokubanzi phakathi kwe-5 ukuya kwi-20 kW. Ezinye iimodeli, ezifana ne-COP4050 nge-ATLAS kunye ne-HL2000 ye-TAMROCK, ifikelela kuma-40 kW, ngelixa i-HL4000 ifikelela kuma-70 kW.

③ Isantya sokuCima ngokukhawuleza: Ngokuqhelekileyo ukuphumeza umlinganiselo we-1-3 m / min.

④ Ukusebenza okuphezulu: Ukusebenza kakuhle kwe-hydraulic rock drills ngokwabo kunokufikelela kwi-50%, kwaye iimpompo ze-hydraulic zisebenza ngakumbi kune-air compressors. Ngenxa yoko, usetyenziso lwamandla lulonke luphezulu kakhulu kunolo lweenkqubo zokugrumba amatye emoyeni.

2. Izinto ezingeloncedo kwi-Hydraulic Rock Drills

① Ilahleko yoThutho lwaMandla: Ekubeni i-rock drill ibekwe phezulu kwintonga yokomba, ilahleko yokuhanjiswa kwamandla iyanda ngobunzulu obukhulu bomngxuma, okukhokelela kukuncipha kwesantya sokomba.

② I-High Drill Rod Wear: Njengoko amandla e-hydraulic rock drills enyuka, uxinzelelo kwi-drill rod nalo luyanda, olukhokelela kumazinga aphezulu omonakalo. Nangona itekhnoloji efana ne-Atlas Copco's casing drilling inceda ukunciphisa uxinzelelo, zonyusa iindleko kwaye ziyasilela ukuyicombulula ngokupheleleyo ingxaki, ngaloo ndlela zinciphisa amandla okuphuma kwe-drill. Umzekelo, ngelixa amandla e-COP4050 elinganiswe kwi-40 kW, yi-30 kW kuphela esetyenziselwa ukugrumba umngxuma onzulu ukunciphisa uxinzelelo kwisixhobo.

③Ukutenxa kumngxuma wamanzi: Iintonga zokomba zinyamezela zombini amandla empembelelo kunye netorque, ekhokelela ekugotyweni kunye nokuguqulwa, okunciphisa ukuchaneka kwequla.

3. Izinto ezilungileyo zePhantsi-kumngxuma (DTH)Iidrills

① Akukho Ilahleko yoThumelo lwaMandla: Ihamile ichaphazela ngokuthe ngqoi-drill bit, ukuphelisa imfuno yokudluliselwa kwamandla okuchaphazela nge-drill rod, ukuqinisekisa isantya sokomba esingaguqukiyo kungakhathaliseki ubunzulu.

② I-Boreholes eNgqongileyo: Intonga ye-drill inobukhuni obuphezulu, ayixhomekeke kwimpembelelo yempembelelo, kwaye ihambisa i-torque kuphela ngoxinzelelo oluncinci lwe-axial. Oku kuthintela ukugoba kunye nokuguqulwa, ukuqinisekisa amaqula athe ngqo kwaye agudileyo. Uqheliso lwe-DTH lusebenza ngcono kulwakhiwo oluqhekekileyo, istrata etyekeleyo, okanye ukuqina kwamatye okuguquguqukayo.

③ Ukususwa kobutyobo okuSebenzayo: Isiphakathi samandla siphinda kabini njengendawo yokugungxula, icoca ngokucokisekileyo iqula kwaye inqande ukugrunjwa kakhulu.

④ Ingxolo ePhantsi: Kuba impembelelo yenzeka kumazantsi equla, ingxolo isezantsi kakhuluizixhobo eziphezulu zesando.

⑤ Ukusebenziseka okuBanzi: Ngaphandle kolwakhiwo oluthambileyo kakhulu, uqheliso lwe-DTH lusebenza ngokugqibeleleyo kuzo zonke iindidi zamatye, ukodlula uqheliso lwamatye oluphezulu kwidayamitha nobunzulu obufikelelekayo.

Ukunikezelwa kwezi nzuzo, ukugrumba kwe-DTH kuthathwa ngokubanzi njengolona khetho lungcono, kunye ne-90% yeekwari zaseBritane zisebenzisa le ndlela.

4. Izinto ezingeloncedo kwi-Pneumatic DTH Drills

① Uxinzelelo oluphantsi kunye namandla: I-drawback ephambili ye-pneumatic DTH drills luxinzelelo lwazo lomoya oluphantsi kunye namandla aphumayo, okukhokelela kwizantya zokomba ezicothayo. Ngelixa ukuqhubela phambili kunyuse uxinzelelo lomoya ukuya kwi-2.5 MPa, oku kusengaphantsi kakhulu koxinzelelo lwehydraulic yokwenziwa kwamatye. Ngaphezu koko, iicompressor zomoya zoxinzelelo oluphezulu ziyabiza, zifuna amandla aphezulu okuqhuba, zivelise ingxolo eyongezelelekileyo, kwaye ziphulukane nokusebenza kakuhle kwiindawo eziphakamileyo.

② Ukusetyenziswa kwamandla aphantsi ngokuSebenzayo: I-Pneumatic DTH drills idla ngokuphindwe kathathu amandla angaphezulu kwimitha egrunjiweyo kune-hydraulic rock drills.

5. Ukusetyenziswa kweHydraulicIzando ze-DTH

Ukudibanisa iingenelo ze-hydraulic rock drill (uxinzelelo oluphezulu kunye nokusebenza kakuhle) kunye ne-DTH drills (i-boreholes ethe tye), i-Hausherr yaseJamani iphuhlise i-"Rapid Hydraulic DTH Drill" ekuqaleni koo-1990. Zombini iindlela zayo zokujikeleza kunye neempembelelo ziqhutywa ngamanzi. Ihamile inemigca emibini yeoli yokubonelela kunye nokubuyisela. Iidrill ezikhawulezayo zifumaneka kwii-diameter ezintathu: 90 mm, 115 mm, kunye ne-150 mm, zilungele imigodi enobubanzi obuyi-100-125 mm, 127-156 mm, kunye ne-168-230 mm, ngokulandelanayo.

Uvavanyo lokuthelekisa phakathi kwe-HBM80S ye-HBM80S ye-pneumatic DTH drill ye-HBM80S ye-pneumatic efanayo ibonise ukuba, kwi-borehole elinganayo (125 mm) kunye nobunzulu (36 m), i-Rapid ibonise inzuzo ebalulekileyo yezoqoqosho ngamandla e-injini aphantsi, ukusetyenziswa kwe-fuel, kunye nomlinganiselo wokusetyenziswa kwe-oyile ye-0.46, 0.46, kunye ne-0.46, kunye ne-0.

6. Ukusetyenziswa kweeHammers ezinamanzi aHydraulic

I-LKAB yaseSweden kunye ne-G-Drill encedisayo iphuhlise i-“Wassara Water-Powered DTH Hammer” ekupheleni koo-1980. Ukusebenzisa amanzi omgodi ahluziweyo njengento ephakathi, isebenza ngoxinzelelo lwe-18-20 MPa kunye namazinga okuhamba kwe-200-300 L / min. Ngezantya zokomba eziqhelekileyo ezingama-850 mm/min, zigqwesa iihamile zepneumatic (ngokuqhelekileyo i-320 mm/min).

Ihamile yakwaWassara ibonise ukusebenza okugqwesileyo, okufana nokunciphisa ukunxaxha kwamaqula ngesiqingatha kunye nokwandisa imveliso ngama-86% kwimigodi yeLKAB. Izicelo ziquka ukugrunjwa kwendlela kaloliwe engaphantsi komhlaba eNew York kunye nokwembiwa kwe-geothermal e-Switzerland, apho igqibezele iqula elingama-599.8 m ngeentsuku ezi-5, xa kuthelekiswa neeveki ezi-3 zoqheliso olujikelezayo.

7. Uthelekiso: I-Hydraulic Water-Powered vs. Hydraulic Fluid-Driven Hammers

IiHammers ezinamanzi: Sebenzisa uxinzelelo lwamanzi olungatshintshiyo, ukufezekisa ukusebenza kakuhle okuphezulu kunye nesantya sokomba, ezifanelekileyo kwizicelo zemigodi.

Izando eziqhutywa ngolwelo: Sebenzisa uxinzelelo lwamanzi oluguquguqukayo kwaye ngokubanzi lukhawulelwe ekugrunjweni komhlaba ngoxinzelelo oluphantsi (0.5–4 MPa) kunye nokusebenza kakuhle (

8. Isiphelo

I-hydraulic kunye namanzi anamandlaIihamile ze-DTHukudibanisa iingenelo ze-top-hammer hydraulic drills kunye ne-pneumatic DTH hammers, enikezela ukusetyenziswa kwamandla aphantsi, isantya sokomba okukhawulezayo, kunye nemigodi ethe tye. Isixhobo esidityanisiweyo samandla kunye nokugungxulwa kwenza iihamile ezisebenza ngamanzi zithembise ngakumbi kuphuhliso lwexesha elizayo.
