JSC Pokrovsky Rudnik yog lub lag luam kub loj hauv Far East. Thawj qhov kub tau tsim los ntawm lub mine hauv xyoo 1999. Lub ore processing cog tau tsim nyob rau hauv 2001. Lub mine yog nyob rau hauv lub Magdagachinsky koog tsev kawm ntawv ntawm lub Amur cheeb tsam, nyob ze lub zos ntawm Tygda. Los ntawm qhov chaw nruab nrab hauv cheeb tsam, lub nroog Blagoveshchensk, ntawm qhov deb li ntawm 600 mais.

Resource base

Pokrovskoye deposit (mine) nyob rau sab qab teb ciam teb ntawm Mongolian-Okhotsk geological fold system. Nyob rau hauv cov chaw no muaj ib tug dav mineralized cheeb tsam, uas yog txuam nrog kev sib cuag ntawm tectonic daim hlau. Qhov tso nyiaj yog ib txheej ntawm tsib loj, feem ntau kab rov tav, ore lub cev. Mineralization ntawm kub ore yog nyob rau hauv quartz leeg, ntawm granitoids thiab volcanic pob zeb tsim nyob rau hauv Mesozoic geological era.

Kub los ntawm kuv
Kub los ntawm kuv

Gold mineralization nce mus txog qhov tob ntawm yuav luag 240 meters. Ntawm Pokrovsky mine, muaj 2 lub ntsiabzones:

  • Pokrovka-1, qhov chaw tseem ceeb thiab lub ntsiab rau kev rho tawm cov ore kub;
  • Pokrovka-3, nyob ntawm qhov deb li ntawm 400 meters ntawm thawj cheeb tsam.

Lub ntsiab tso nyiaj ntawm kuv yog Pokrovka-1. Cov no yog plaub lub cev ore, uas hu ua Lake, New, Zeya thiab Main.

Tshawb nrhiav cov khoom muaj txiaj ntsig zoo thaum lub sijhawm lawv pib mining muaj li 56 tons ntawm kub thiab txog 100 tons ntawm nyiaj.

Lub koom haum, thev naus laus zis, kev tsim kho vaj tse

Pokrovsky Mine yog ib feem tseem ceeb ntawm Petropavlovsk Pawg Tuam Txhab (Petropavlovsk PLC). Lub npe qub ntawm cov qauv yog Peter Hambro Mining, uas tau tsim nyob rau hauv 1994. Nws tau tsim los ntawm pej xeem Lavxias P. Maslovsky thiab neeg Askiv neeg Askiv P. Hambro.

Pokrovsky mine tau dhau los ua thawj qhov kev lag luam mining thiab metallurgical hauv Russia tsim los ntawm kos.

Lub mining thiab hydrometallurgical cog kev ua haujlwm ntawm Pokrovskoye tso nyiaj yog ib lub lag luam loj thiab niaj hnub Lavxias teb sab nyob rau sab hnub tuaj. Tus nqi ntawm cov kub ua nyob rau hauv lub mine no yog ib tug ntawm cov qis tshaj nyob rau hauv lub ntiaj teb no. Qhov no yog vim lub fact tias nyob rau hauv ze ze muaj ib tug txhim khu kev qha infrastructure thiab muaj zog muaj peev xwm nyob rau hauv daim ntawv ntawm ib tug hydroelectric power station ntawm tus dej Zeya. Thiab tseem yog vim lub fact tias txoj kev loj hlob ntawm lub hauv paus kub deposit yog nqa tawm nyob rau hauv ib tug qhib txoj kev.

Tam sim no, yuav luag 2,800 tus neeg ua haujlwm ntawm lub mine (suav nrog kev sib hloov). Ua tsaug rau kev siv zog ntawm Petropavlovsk Pawg Tuam Txhab, ntawm noib tug niaj hnub infrastructure tau tsim, uas yog txawm peem rau nrog ib tug lub hwj chim mov system, dej mov, kev nkag mus rau hauv lub tsev. Lub tshuab cua sov thiab lub chaw pw hav zoov rau cov neeg ua haujlwm hloov chaw tau ua rau ntawm lub mine. Nws muaj nws qhov chaw kuaj geological niaj hnub, nrog rau kev lag luam thiab kev tswj hwm ntawm cov tsev thiab cov qauv.

Lub mine nyob rau hauv Amur Region, ntawm qhov deb ntawm 7 km ntawm lub zos Tygda.

chaw nyob: Amur cheeb tsam, Tygda zos, Magdagachinsky koog tsev kawm ntawv, Sovetskaya txoj kev, tsev 17.

keeb kwm keeb kwm

Keeb kwm ntawm kev khawb kub ntawm Pokrovsky mine pib xyoo 1999. Tom qab ntawd thawj cov hlau muaj txiaj ntsig tau txais ntawm no siv txoj kev heap leaching.

Nws nyob ntawm kuv qhov no tias txoj kev no tau pib siv txhua xyoo, hauv cov huab cua nyuaj heev. Cov kev daws teeb meem tshwj xeeb siv los ntawm no tau raug patented.

Tsis tas li, kev khawb kub yog ua los ntawm kev txhawb nqa. Rau lub hom phiaj no, lub mining thiab hydrometallurgical cog tau tsim ntawm lub mine.

Production

Cov nroj tsuag hydrometallurgical niaj hnub tau muab tso rau hauv kev ua haujlwm hauv xyoo 2002, thiab tib lub xyoo nws pib "muab" thawj kub. Los ntawm lub caij nplooj zeeg xyoo 2004, nws lub peev xwm tau nce ntau, vim tias nws tau pib ua tiav yuav luag ib thiab ib nrab lab tons ntawm ore hauv ib xyoos.

Kev ua haujlwm ntawm lub mine yog ua los ntawm cov khoom siv niaj hnub thiab cov tshuab, uas yog cov cuab yeej ntawm Petropavlovsk Pawg Tuam Txhab. Lub nkoj muaj xws li Caterpillar bulldozers, excavators xws liEKG-5, nrog rau Belarusian BelAZ pob tseg tsheb thauj khoom nrog lub peev xwm nqa ntawm 45 tons.

Txog tsis ntev los no, lub tuam txhab tau tswj hwm kom ruaj khov ntim ntawm cov mining kub. Cov pob zeb kub tau raug khawb hauv qhov qhib hauv ob qhov chaw, uas yog, hauv Pioneersky thiab Molodezhny quarries. Tsis ntev los no, JSC "Pokrovsky Mine" pib qhia cov thev naus laus zis tshiab. Txij li thaum cov hlab ntsha uas muaj cov kab mob kub tau xyaum tas li, qhov teeb meem ntawm kev rho nyiaj thiab kub los ntawm cov khoom pov tseg tsim los ntev yog nyob rau hauv cov txheej txheem.

Cov ntaub ntawv rau kev tsim kub ntawm Pokrovsky mine hauv Amur Thaj av tau sau tseg hauv 2009. Tom qab ntawd tsim 199,600 troy ounces. Nyob rau hauv lub xyoo tom ntej, kub ntau lawm tau khaws cia nyob rau theem ntawm 135,000-145,000 ounces ib xyoos twg. Txawm li cas los xij, txij li xyoo 2012, vim yog cov hlab ntsha kub tas li, cov khoom kub tau maj mam poob qis.

Prospects

Tam sim no, Petropavlovsk pawg tuam txhab ua haujlwm tshawb nrhiav geological thiab tshawb fawb raws thaj tsam ntawm Pokrovskoye teb. Cov txiaj ntsig tau ua rau peb hais tias lub neej ntawm kuv yuav txuas ntxiv mus.

Tshaj tag nrho cov keeb kwm ntawm Pokrovsky mine, nws tau tsim yuav luag 1,850,000 ooj kub. Tam sim no nws yog nyob rau theem kawg ntawm depletion ntawm lub ntsiab Pokrovka-1 teb. Raws li qhov tshwm sim, suav nrog rau kev txuas ntxiv ntawm kev siv cov khoom tsim thiab kev tsim kho vaj tse, cov phiaj xwm pib ua tiav: lub mine yuav hloov mus rau hauv kev lag luam,uas yuav ua cov refractory ores siv txoj kev tshiab.

Tib lub sijhawm, Petropavlovsk pawg tuam txhab lag luam tsom tig Pokrovsky Mine OJSC mus rau hauv qhov chaw mining kub. Nws siv cov thev naus laus zis niaj hnub flotation-autoclave rau kev rho tawm kub, uas yuav ua rau kom tau txais cov hlau zoo nkauj uas tsis tuaj yeem tau los ntawm kev ua ib txwm ua.

Pib hloov pauv

Tam sim no, kev ua haujlwm tab tom pib ntawm Pokrovsky Mine txhawm rau tso lub HUB no. Txog qhov kawg no, kev tshawb fawb loj tau ua tiav ntawm lub Hoobkas hauv nroog Blagoveshchensk (cov qauv kuaj). Nyob ntawd, cov qauv raug kawm thiab cov neeg ua haujlwm raug cob qhia rau cov kev hloov pauv tom ntej.

Nws xav tias tom qab lub community launch ntawm Pokrovsky AGK, nws yuav tig mus rau hauv lub zog tshaj plaws thiab technologically advanced autoclave kub mining complex nyob rau hauv Lavxias teb sab Federation, yoog mus ua hauj lwm nrog ntau yam ores uas muaj ntau yam ntxwv.

Rau lub hom phiaj no, LLC Pokrovsky AGK (Pokrovsky Autoclave Hydrometallurgical Plant) tau tsim nyob rau xyoo 2016.
