Ọganihu dị na Teknụzụ Drilling DTH na mmiri na-akwado Hydraulic.

1. Uru nke Hydraulic Rock Drills

① Nrụgide hydraulic dị elu: Ọ na-esite na 10 ruo 25 MPa, na-enwe omume na oke oke. Nke a dị ọtụtụ ruo ọtụtụ ugboro dị elu karịa nrụgide pneumatic.

② Ike mmepụta dị elu: N'ozuzu n'etiti 5 ruo 20 kW. Ụdị ụfọdụ, dị ka COP4050 nke ATLAS na HL2000 nke TAMROCK, ruru 40 kW, ebe HL4000 na-enweta ihe ruru 70 kW.

③ Ọsọ ịkwọ ụgbọ mmiri: Ọ na-enwetakarị ọ̀tụ̀tụ̀ mgbọ ala nke 1–3 m/min.

④ Ịrụ ọrụ dị elu: Ịrụ ọrụ nke nkume nkume hydraulic onwe ha nwere ike iru 50%, na nfuli hydraulic na-arụ ọrụ nke ọma karịa ikuku compressors. N'ihi ya, ojiji ike n'ozuzu ya dị elu nke ukwuu karịa nke sistemụ egwu pneumatic rock.

2. Ọdịmma nke Hydraulic Rock Drills

① Ike nnyefe ike: Ebe ọ bụ na nkume a na-egwupụta ihe dị n'elu mkpanaka mgbanaka ahụ, mfu nnyefe ume na-abawanye na omimi oghere dị ukwuu, na-eme ka ọsọ ọsọ na-ebelata.

② Igwe eji egwu egwu dị elu: Ka ike nke hydraulic rock drills na-abawanye, nrụgide dị na mkpanaka ọkpọ ahụ na-abawanye, na-eduga na ọnụego mmebi dị elu. Ọ bụ ezie na teknụzụ dị ka ịgbapu casing nke Atlas Copco na-enyere aka ibelata nchekasị, ha na-abawanye ọnụ ahịa ma ghara idozi nsogbu ahụ kpamkpam, si otú ahụ na-amachi ike mmepụta ihe. Dịka ọmụmaatụ, ebe a na-enye ike COP4050 na 40 kW, naanị 30 kW na-eji olulu miri emi mee ihe iji belata nrụgide na akụrụngwa.

③Mwepu nke ime oghere: Ogwe osisi na-atachi obi ma ike mmetụta na ike, na-eduga n'ihulata na nrụrụ, nke na-ebelata izi ezi nke olulu mmiri.

3. Uru nkeOghere ala (DTH)Ọkpụkpụ

① Enweghị mfu nnyefe ike: hama na-emetụta ya ozugboogwugwu bit, na-ekpochapụ mkpa maka mmetụta nyefe ike site na mkpịrị osisi, na-ahụ na-agba ọsọ na-agbanwe agbanwe n'agbanyeghị omimi.

② olulu mmiri kwụ ọtọ: mkpanaka mkpọ ahụ nwere nnukwu nkwụsi ike, anaghị etinye aka na ike mmetụta, ma na-ebufe naanị torque na obere nrụgide axial. Nke a na-egbochi ịgbagọ na nrụrụ, na-eme ka olulu mmiri kwụ ọtọ ma dị larịị. Ihe omume DTH na-arụ ọrụ nke ọma n'ụdị gbajiri agbaji, strata nwere mmasị, ma ọ bụ isi ike nkume na-agbanwe agbanwe.

③ Mwepụ mkporisị nke ọma: Igwe ọkụ na-agbakọ okpukpu abụọ dị ka ihe na-agbapụta mmiri, na-ehicha oghere nke ọma ma na-ezere ịkwọ ụgbọ mmiri.

④ mkpọtụ dị ala: Ebe ọ bụ na mmetụta na-eme na olulu mmiri, mkpọtụ dị ala karịaelu-hama akpu.

⑤ Ngwa ngwa ngwa: Ewezuga usoro dị nro, DTH na-arụ ọrụ nke ọma n'ụdị okwute niile, na-akarị elu-hammer rock drills na dayameta olulu mmiri na omimi.

N'inye uru ndị a, a na-ahụta mkpọpu DTH dị ka nhọrọ kacha mma, ebe 90% nke ebe a na-egwu mmiri Britain na-agbaso usoro a.

4. Ọdịmma nke Pneumatic DTH Drills

① Nrụgide dị ala na ike: Ihe ndọghachi azụ nke mbụ nke pneumatic DTH drills bụ ikuku ikuku ha dị ala na ike mmepụta, na-eduga n'ịgba ngwa ngwa ngwa ngwa. Ọ bụ ezie na ọganihu ebuliwo elu ikuku ruo 2.5 MPa, nke a ka dị n'okpuru nrụgide hydraulic nke nkume egwu. Ọzọkwa, ikuku compressors dị elu dị oke ọnụ, chọrọ draịva ike dị elu, na-emepụta mkpọtụ karịa, ma na-efunahụ arụmọrụ nke ukwuu na mpaghara elu dị elu.

② Ịrụ ọrụ ike dị ala: Pneumatic DTH drills na-eri ike ugboro atọ karịa otu mita a gbapụrụ karịa ihe ọkpụkpụ hydraulic rock.

5. Ngwa nke hydraulicDTH Hammers

Iji chịkọta uru nke igwe okwute hydraulic rock (nnukwu nrụgide na arụmọrụ) na DTH drill (olulu mmiri kwụ ọtọ), Germany's Hausherr mepụtara “Rapid Hydraulic DTH Drill” na mbido 1990s. Ma usoro ntụgharị ya na usoro mmetụta ya bụ hydraulically na-ebugharị. Hama nwere ahịrị mmanụ abụọ maka ọkọnọ na nloghachi. Ngwunye ngwa ngwa dị na dayameta atọ: 90 mm, 115 mm, na 150 mm, dabara maka olulu mmiri nwere dayameta nke 100-125 mm, 127-156 mm, na 168-230 mm, n'otu n'otu.

Nnwale atụnyere n'etiti Rapid na Hausherr's HBM80S pneumatic DTH drill gosiri na, maka otu dayameta olulu mmiri (125 mm) na omimi (36 m), ngwa ngwa gosipụtara uru akụ na ụba dị ịrịba ama na ike engine dị ala, oriri mmanụ, na mmanụ mmanụ mmanụ nke 0.46, 0.46, na nkwanye ùgwù 0.46, na nkwanye ùgwù 0.46.

6. Ngwa nke hydraulic Water-Powered Hammers

LKAB nke Sweden na onye enyemaka ya G-Drill mepụtara “Wassara Water-Powered DTH Hammer” na ngwụcha 1980s. N'iji mmiri m chara acha dị ka onye na-ahụ maka ihe, ọ na-arụ ọrụ na nrụgide nke 18-20 MPa na ọnụego 200-300 L / min. Na nkezi nke mkpọpu mmiri nke 850 mm / min, ọ na-eme ka hama pneumatic (ọ na-abụkarị 320 mm / min).

Hama Wassara egosipụtala arụmọrụ pụrụ iche, dị ka ibelata mgbanaka olulu mmiri site na ọkara yana ịbawanye nrụpụta site na 86% na ogbunigwe LKAB. Ngwa gụnyere grouting ụzọ ụgbọ oloko na New York na mkpọ ala geothermal na Switzerland, ebe ọ rụchara olulu mmiri 599.8 m n'ime ụbọchị 5, ma e jiri ya tụnyere izu atọ na mgbagharị rotary ọdịnala.
