Mining av Stabilization nrog siab -Lub zog Geosynthetics
Weiwo muab engineeringed geosynthetic kev daws teeb meem rau mining, tackling nqes hav stability, subgrade reinforcement, yaig tswj, thiab kua. Peb cov khoom siv ruaj khov, tus nqi-cov tshuab ua haujlwm tau zoo ua kom lub sijhawm ntev- ua haujlwm tau zoo raws li qhov chaw hnyav.
Weiwo High-Density Polyethylene (HDPE) Geomembrane
Daim ntawv thov:Heap leaching hauv ob sab phlu, lub ntsiab impermeable txheej ntawm tailings dam, evaporation pas dej.
Siv cov-cov ntaub ntawv nkauj xwb zoo thiab yog tsim tshwj xeeb rau cov tshuaj lom neeg ib puag ncig thiab kev ntxhov siab ntawm lub cev ntawm cov chaw mining.
Environmental Stress Cracking Resistance (ESCR):> 500 teev (ASTM D5397), xyuas kom tsis txhob tawg tawg nyob rau hauv heap leaching loads.
Cov ntsiab lus carbon dub:2.0% - 3.0%, muab kev ua haujlwm ntev ntev - UV tiv thaiv, haum rau cov pas dej evaporation.
Tensile Properties:Extremely high yield strength and elongation at break (>700%), muaj peev xwm ua kom muaj kev sib haum xeeb tsis sib xws thaum lub sij hawm ntim khoom.
Thickness Ntau:1.0mm - 3.0mm xaiv tau, ua tau raws li ntau yam kev xav tau ntawm engineering los ntawm kev siv cov dej phwj tuaj mus rau qhov hnyav -cov dej tob tob.
Reinforced geosynthetic av nplaum liner (GCL)
Daim ntawv thov thaj chaw: Tailings dam thib ob seepage tiv thaiv, composite seepage tiv thaiv system, ib puag ncig tiv thaiv barrier.
GCL siv rab koob- txheej txheem xuas nrig ntaus los xauv ntuj sodium-raws li bentonite nruab nrab ntawm ob txheej ntawm geotextile, ua rau lub ntsej muag ntse uas "kho nws tus kheej thaum raug dej".
Bentonite expansion ntim:Ntau dua los yog sib npaug rau 24 mL / 2g, Xyuas kom muaj qhov tsis tshua muaj hydraulic permeability coefficient.
Permeability:Tsawg dua lossis sib npaug li 5 × 10-11m / s, Nws muab cov dej tsis zoo dua li cov av nplaum tuab, txawm tias nyias nyias.
Peel zog:Ntau dua lossis sib npaug li 66 N / 10cm (ASTM D6496), Cov koob - punched fibers yog nruj nreem kaw kom tiv thaiv interlayer slippage thaum lub sij hawm txoj kab nqes.
Tus kheej- kho cov khoom:Txhawm rau hais txog qhov muaj peev xwm rau cov pob zeb me me hauv kuv cov dej, bentonite nthuav dav thaum sib cuag nrog dej thiab tuaj yeem tuaj yeem sau qhov pores txog li 1 cm inch.
Siab-lub zog polyester (PET) warp-knitted geogrid
Daim ntawv thov:Reinforced av retaining phab ntsa, mine txoj kev reinforcement, tailings dam reinforcement.
Ua nrog siab -molecular- hnyav polyester fiber warp-knitted mesh, coated nrog ib tug tshwj xeeb polymer nplaum, tshwj xeeb yog tsim rau siab - load mining engineering.
Qhov kawg Tensile Strength:Bidirectional / unidirectional xaiv tau, mus txog 800 kN / m - 1200 kN / m.
Low Creep:Siab ntev heev -lub sij hawm tuav lub zog nyob rau hauv lub neej tsim (50-100 xyoo), ua kom muaj kev ruaj ntseg ntawm cov qauv rau kev ua haujlwm mining mus tas li.
Creep Shrinkage Coefficient:Tsim los rau hnyav geological tej yam kev mob nyob rau hauv mines, lub creep coefficient yog qis dua 1.45 (10,000-teev xeem).
Interface Efficiency:Siv cov cuab yeej warp knitting, lub siab ntawm lub zog tso cai rau kev sib cuam tshuam zoo heev nrog kev sib sau ua ke.
Drainage & Reinforcement Systems
Dhau li ntawm kev tiv thaiv seepage, kev ruaj ntseg ntawm mine lub geological qauv kuj tso siab rau kev kho dej kom zoo.
Geocomposites (composite drainage network)
Daim ntawv thov: hauv qab tso dej ntawm heap leaching teb, tailings dam drainage.
High conductivity: Tswj cov dej zoo tshaj plaws hauv kev ua haujlwm siab nyob rau hauv siab loads (siab rockfill siab), ceev tso tawm leachate.
Kev tiv thaiv-tsim thaiv kab mob: Cov txheej txheem geotextile lim sib xyaw tiv thaiv cov khoom tsis zoo los ntawm kev nkag mus rau hauv cov tub ntxhais dej, kom ntseeg tau tias lub kaw lus tseem tsis muaj kev cuam tshuam - pub dawb rau lub sijhawm ntev.
