Tackling Siab -Stress Rock Bursts: Strategic Bolting Patterns for Challenging Land
Hauv kev sib sib zog nqus- theem mining, qhov tob dua peb mus, qhov av hnyav dua. Ib qho xwm txheej txaus ntshai tshaj plaws mining engineers ntsej muag yogPob zeb tawg-tam sim ntawd, tsausmuag tso tawm ntawm lub zog strained hauv pob zeb loj.
Thaum koj lub mine ua haujlwm nyob rau hauv siab geostress, tsoos "static" kev txhawb nqa tsis txaus. Koj xav tau ib txoj hauv kev dynamic, lub tswv yim rau kev txhawb nqa hauv av. Phau ntawv qhia no tshawb txog yuav ua li cas optimize kojbolting qauvthiab txhawb cov txheej txheem los txo cov kev pheej hmoo ntawm siab -kev nyuaj siab geological tej yam kev mob.
Lub pob zeb tawg tshwm sim thaum lub pob zeb loj tsis tuaj yeem khaws cov kev ntxhov siab tectonic ntxiv lawm, ua rau tsis ua haujlwm tam sim ntawd. Hauv cov xwm txheej no, tus qauv bolts tsis yog tuav qhov hnyav xwb; lawv yuav tsum nqus kinetic zog. Yog tias koj qhov kev txhawb nqa dhau lawm "stiff," nws yuav nrawm nrawm nrawm. Yog tias nws "tsis muaj zog," nws tsuas yog raug thawb tawm ntawm lub qhov.
2. Kev daws: Yielding Support Systems
Hauv siab - thaj tsam kev ntxhov siab, peb txav los ntawm kev txhawb nqa nruj mus rauYielding Support. Lub hom phiaj yog tso cai rau lub pob zeb kom deform nyob rau hauv kev tswj hwm yam tsis muaj kev sib tsoo.
Dynamic Anchoring:Kev sivCable Anchorsnrog tshwj xeeb debonding lub tes tsho tso cai rau lub thauj tog rau nkoj "stretch" nyob rau hauv kev ntxhov siab es tsis txhob snapping tam sim ntawd.
Zog-Nqus Mesh:TxujMining Hlau Meshtuaj yeem tawg tau yooj yim hauv pob zeb tawg. Nyob rau hauv siab - thaj chaw muaj kev pheej hmoo, peb pom zoo kom siab - tensile, galvanized mesh uas muab cov nyhuv "cradle", muaj cov khib nyiab txawm tias thaum muaj kev kub ntxhov.
Qhov layout ntawm koj bolts-theBolting Qauv- yog thawj kab kev tiv thaiv. Hauv qhov siab -kev nyuaj siab, qhov sib txawv "tus qauv" feem ntau tsis txaus.
Nce ntom ntom:Txo qhov sib nrug ntawm cov bolts (piv txwv li, los ntawm 1.2m mus rau 0.8m) tsim kom muaj kev sib xyaw ua ke ntau dua "beam" ntawm pob zeb, ua rau tag nrho cov qauv nruj ntawm lub ru tsev.
Installation ntawm qhov chaw:Ib tug staggered qauv xyuas kom meej tias tsis muaj "cov kab tsis muaj zog" nyob rau hauv txoj kev, tiv thaiv shear tsis ua hauj lwm raws lub ru tsev.
Peb -Txoj Kev Tiv Thaiv:
Primary Bolt:Siab -lub zogSab laug / sab xis- Tes Xov Boltsrau kev txhawb nqa tam sim ntawd.
Surface Control:Hnyav-dutyDomal Phajua ke nrog siab - tensile mesh los tswj cov pob zeb tawg tawg.
Sib sib zog nqus Reinforcement:Ntev - ntau yamCable Anchorsuas ncav mus rau hauv qhov ruaj khov, tsis yog -txoj kev nyuaj siab pob zeb strata dhau ntawm qhov tawg- thaj chaw uas nyob ib puag ncig.
4. Qhov tseem ceeb ntawm "System Integrity"
Lub pob zeb tawg yog qhov ua tsis tiav. Yog tias koj lub bolt tuav, tab sis kojAnchor Phajbuckles, tag nrho cov system ua tsis tau. Yog tias koj lub mesh unzips, lub phaj tsis muaj dab tsi los tawm tsam.
NtawmZhongfu Mining, peb haisKev them nyiaj yug Integrated. Peb cov tshuab yog tsim los kom cov ntsia liaj qhov rooj, lub phaj, thiab cov mesh yog structurally calibrated los ua ib tug. Thaum lub hauv paus hloov, peb daim hlau yog tsim los tiv thaiv lub zog, thiab peb cov mesh yog woven los tuav nws cov qauv ciam teb, muab cov mine cov neeg ua hauj lwm tseem ceeb ntxiv vib nas this ntawm kev nyab xeeb.
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 tsoo 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 casing thiab tiv thaiv borehole vau, 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.
Xaus: Kev Nyab Xeeb Los Ntawm Engineering
High -kev nyuaj siab mining tsis tas yuav txhais tau tias siab -frequency xwm txheej. Los ntawm kev txav mus rau dynamic, yielding kev txhawb nqa systems thiab lub tswv yim densifying koj bolting qauv, koj muaj peev xwm tswj tau zoo cov kev pheej hmoo ntawm pob zeb tawg.
NtawmZhongfu Mining, peb muab ntau tshaj li cov hlau xwb -peb muab kev thaj yeeb ntawm lub siab uas tuaj nrog engineering- qib kev txhawb nqa. Txawm hais tias koj xav tau kev cai cable ntev los yog cov mesh reinforced, peb pab neeg yog npaj los pab koj txhim kho koj lub mine tiv thaiv qhov nyuaj geological tej yam kev mob.
