Sab laug- Tes vs. Txoj Cai- Tes Xov Pob Zeb Bolts: Cov Lus Qhia Tseem Ceeb rau Mining Engineers
Nyob rau hauv qhov xav tau ib puag ncig ntawm cov mining hauv av, kev ua tiav ntawm kev txhawb nqa hauv av feem ntau los rau cov ntsiab lus me tshaj plaws. Ib qho kev nthuav dav yog qhovxov directionntawm pob zeb bolt. Thaum ob leegSab laug- Tes (LH)thiabTxoj cai - Tes (RH)xov bolts yog siv thoob ntiaj teb, xaiv qhov tsis ncaj ncees lawm tuaj yeem ua rau kev teeb tsa ua tsis tiav thiab muaj kev nyab xeeb.
Phau ntawv qhia no tshawb txog engineering logic tom qab xov kev taw qhia thiab yuav ua li cas kom ntseeg tau tias koj xaiv phim koj qhov chaw xav tau.
Lub hauv paus tseem ceeb hauv kev xaiv xov kev taw qhia yog kev sib hloov ntawm kojbolting rig (Roof Bolter lossis Jumbo).
Mechanical Logic:Lub pob zeb ntsia liaj qhov rooj yuav tsum tau threaded kom lub rig tig thaum lub sij hawm kawg ntawm installationnrujlub txiv ntoo tawm tsam lub phaj.
Qhov Risk:Yog tias koj siv txoj cai - tes xov ntsia liaj qhov rooj ntawm lub rig uas tig lub txee -clockwise (CCW) thaum lub sij hawm tensioning, lub tshuab yuav unscrew lub txiv ntseej es kom nruj nws. Qhov no tawm ntawm lub bolt "passive," tsis muab lub zog clamping quab yuam uas yuav tsum tau ua kom ruaj khov pob zeb strata.
2. Kev tshawb fawb ntawm Resin Mixing
Feem ntau cov threaded bolts tau ruaj ntseg sivResin Capsules. Cov kev taw qhia xov yog qhov tseem ceeb rau cov txheej txheem tshuaj sib txuas.
Raws li lub bolt yog spun rau hauv lub qhov:
Cov nyhuv Auger:Cov xov ua raws li auger (ntsia hlau conveyor). Yog hais tias qhov kev sib hloov yog sib npaug ntawm cov xov kev taw qhia, cov resin raug yuam mus rau tom qab ntawm lub qhov. Qhov no ua kom cov resin sau tag nrho cov kab nrib pleb thiab fissures, tsim kom muaj 100% daim ntawv cog lus.
Ua tsis tiav Mixing:Yog tias qhov kev sib hloov tsis raug, cov resin tuaj yeem raug thawb mus rau ntawm lub qhov ncauj ntawm lub qhov, tsim "cua hnab ris" thiab ua rau tsis muaj zog anchorage uas yuav ua tsis tau ib qho kev rub tawm - tawm.
Thaum muaj kev zam, kev lag luam feem ntau ua raws li cov qauv no:
Sab laug- Tes Xov Bolts (CCW):Feem ntau tus qauv hauvCoal Mining(tshwj xeeb tshaj yog nyob rau hauv Australia, South Africa, thiab ib feem ntawm Tuam Tshoj). Qhov no yog vim muaj kev siv dav dav ntawm CCW-rotating bolting technology hauv cov cheeb tsam no.
Txoj cai - Tes Xov Bolts (CW):Ntau tshaj nyob rau hauvHard Rock Mining thiab Civil Tunneling, qhov twg tus qauv clockwise -rotating drilling khoom siv.
4. Vim li cas "System Integrity" tseem ceeb
Ib tug xov tsuas yog zoo li cov accessories uas phim nws. Thaum muab LH lossis RH bolts, tag nrho cov kab ke yuav tsum sib haum:
Txiv ntseej:Ib sab laug- tes txiv ntseej yuav tsis haum txoj cai- tes ntsia liaj qhov rooj.
Anchor phaj:Lub domal lossis tiaj phaj yuav tsum muaj peev xwm tiv taus qhov tshwj xeeb torque-tensioning ntawm cov xov xaiv.
Resin xaiv:Lub sij hawm teem caij ntawm cov resin yuav tsum tau calibrated rau lub rig qhov kev sib hloov ceev kom cov xov zoo sib tov cov khoom ua ntej hardening.
FAQ
Q: Cov qauv thoob ntiaj teb dab tsi ua koj tus kheej -drilling bolts ua raws li?
A: Peb lub tshuab SDA (xws li R- xov thiab T- xov) yog tsim los ntawm nruj raws li ISO 10208 thiab ASTM cov qauv. Peb siv siab - lub zog seamless steel tubing kom ntseeg tau tias muaj zog tensile zoo dua thiab muaj zog txaus rau kev thov cov mining thiab tunneling tej yaam num.
Q: Vim li cas SDA bolts ua haujlwm zoo dua li cov pob zeb pob zeb hauv av tawg?
A: Cov bolts ib txwm xav tau ua ntej -drilled qhov uas feem ntau tawg hauv av xoob. Lub SDA system sib txuas cov drilling, grouting, thiab anchoring rau hauv ib qho kev ua haujlwm. Qhov no tshem tawm qhov xav tau ntawm cov kav dej thiab tiv thaiv lub qhov borehole, txuag txog li 50% ntawm lub sijhawm installation.
Q: Koj cov txiv ntseej kheej kheej ua li cas tuav cov pob zeb tsis sib xws?
A: Peb precision-engineered spherical txiv ntseej (dome ceev), thaum ua ke nrog domed daim hlau, tso cai rau 7 mus rau 10 degrees ntawm angular them. Qhov no ua kom ntseeg tau tias lub ntsia liaj qhov rooj tswj xyuas qhov ruaj ntseg, qhov chaw thau khoom faib tawm txawm tias lub ntsej muag lub ntsej muag tsis sib xws lossis tsis sib xws.
Thaum lub pob zeb bolts yog "khob cij thiab butter" ntawm kev txhawb nqa hauv av,Cable Anchorsyog txoj cai pov hwm qhov kawg rau siab - kev pheej hmoo thiab siab - thaj chaw muaj kev ntxhov siab. Kev nkag siab thaum twg thiab yuav ua li cas los siv qhov sib sib zog nqus cable yog qhov tseem ceeb rau kev tiv thaiv lub ru tsev loj thiab ua kom qhov project ntev.
Nrhiav rau siab - muaj peev xwm txhawb kev daws teeb meem?
Zhongfu Mining muaj siab - tensileCable Anchors, Barrel thiab Wedge sets, thiab customizedAnchor phajkom haum rau koj qhov xav tau tshaj plaws hauv qhov sib sib zog nqus- cov haujlwm tsuas.
