Kwinkqubo yokuveliswa kwemigodi yamalahle, kukho izinto eziqhumayo ezifana negesi kunye nothuli lwamalahle. Ukuze kuqinisekiswe imveliso ekhuselekileyo kunye nokuthintela iingozi zokuqhuma okubangelwa yigesi kunye nothuli lwamalahle, kwelinye icala, umxholo wegesi kunye nothuli lwamalahle emoyeni ophantsi komhlaba kufuneka ulawulwe; kwelinye icala, yonke imithombo yokutshisa kunye nemithombo yobushushu obuphezulu obunokuthi ivuthe igesi kunye nothuli lwamalahle emigodini kufuneka ipheliswe.
Izixhobo zombane zasemgodini zohlulwe zibe ziindidi ezimbini, ezizezi, izixhobo zombane jikelele zasemgodini kunye nezixhobo zombane ezingenoqhushumba.
Umgodi wezixhobo zombane jikelele sisixhobo sombane esingagqabhuki sisetyenziswa kwimigodi yamalahle. Ingasetyenziswa kuphela kwiindawo apho kungekho ngozi yokuqhuma kwerhasi nothuli lwamalahle phantsi komhlaba. Iimfuno ezisisiseko kulo: igobolondo yomelele kwaye ivaliwe, enokuthintela ukudibanisa ngokuthe ngqo kunye neendawo eziphilayo ezivela ngaphandle; ine-drip elungileyo, i-splash kunye nokusebenza kobungqina bokufuma; kukho isixhobo sokungena kwekhebula, kwaye inokuthintela intambo ukuba ingajiki, ikhuphe kwaye yonakalise; kukho isixhobo sokutshixa phakathi kwesibambo sokutshintsha kunye nesivalo socango, njl.
- . Iindidi zezixhobo zombane ezingaqhumiyo emigodini
Ngokweemfuno ezahlukeneyo zobungqina bokudubula, izixhobo zombane ezinobungqina bokudubula kwimigodi yahlulwe ikakhulu ngohlobo lobungqina bokudubula kwemigodi, uhlobo lokhuseleko olwandisiweyo lwemigodi, uhlobo lokhuseleko lwangaphakathi lwemigodi, uhlobo loxinzelelo olulungileyo lwemigodi, uhlobo oluzaliswe yintlabathi yokumbiwa kwemigodi. , uhlobo lwe-cast-in-place uhlobo lwemigodi kunye ne-gas-tight-tight for mining.
- Izixhobo zombane ezingaqhushumbayo emigodini
Into ebizwa ngokuba yi-explosion-proof ithetha ukubeka iindawo eziphilayo zesixhobo sombane kwiqokobhe elikhethekileyo. Iqokobhe linomsebenzi wokwahlula iintlantsi kunye nee-arcs ezenziwe ngamalungu ombane kwiqokobhe ukusuka kumxube oqhushumbayo ngaphandle kweqokobhe, kwaye inokumelana noxinzelelo logqabhuko-dubulo oluveliswa xa umxube oqhushumbayo ungena kwiqokobhe uqhunyiswa ziintlantsi kunye neearcs zeqokobhe. izixhobo zombane kwiqokobhe, ngelixa iqokobhe ingatshatyalaliswa, kwaye kwangaxeshanye, inokuthintela iimveliso eziqhumayo kwiqokobhe ukuba zisasazeke kumxube oqhumayo ngaphandle kweqokobhe. Eli qokobhe likhethekileyo libizwa ngokuba liqokobhe elingatshiyo. Isixhobo sombane esineqokobhe elingatshiyo sibizwa ngokuba sisixhobo sombane esingatshiyo.
- Ukonyuka kwezixhobo zombane zokhuseleko kwimigodi
Umgaqo-ubungqina bokuqhuma kwezixhobo zombane ezikhuselekileyo ezikhuselekileyo kukuba: kwezo zixhobo zombane zemigodi ezingayi kuvelisa i-arcs, iintlantsi kunye namaqondo okushisa ayingozi phantsi kweemeko eziqhelekileyo zokusebenza, ukwenzela ukuba kuphuculwe ukhuseleko lwabo, uchungechunge lwamanyathelo athatyathwa kwisakhiwo, ukuvelisa. inkqubo kunye neemeko zobugcisa zezixhobo, ukwenzela ukuba kuthintelwe izixhobo ekuveliseni iintlantsi, ii-arcs kunye namaqondo obushushu ayingozi phantsi kokusebenza kunye neemeko zokugcwala, kunye nokufezekisa ubungqina bokuqhuma kombane. Ukonyuka kwezixhobo zombane ezikhuselekileyo kukuthatha amanyathelo athile okuphucula umgangatho wokhuseleko ngokubhekiselele kwiimeko zokuqala zobugcisa bezixhobo zombane, kodwa akuthethi ukuba olu hlobo lwezixhobo zombane lunomsebenzi ongcono wokuqhuma ukuqhuma kunezinye iintlobo zezixhobo zombane. Umgangatho wokusebenza kokhuseleko lwezixhobo zombane ezikhuselekileyo azixhomekanga kuphela kwifom yesakhiwo sezixhobo ngokwazo, kodwa kunye nokugcinwa kwendawo yokusetyenziswa kwesixhobo. Kuphela ezo zixhobo zombane ezingavelisi ii-arcs, iintlantsi kunye nokufudumala ngexesha lokusebenza okuqhelekileyo, njengeziguquli, ii-motor, izibane zokukhanyisa, njl., zingenziwa kwizixhobo zombane ezikhuselekileyo.
- Izixhobo zombane ezikhuselekile ngokwangaphakathi emigodini
Umgaqo wobungqina bokudubula kwezixhobo zombane ezikhuselekileyo kukuba: ngokunciphisa iiparitha ezahlukeneyo zesekethe yesixhobo sombane, okanye ukuthatha amanyathelo okukhusela ukunciphisa amandla okukhutshwa kwentlantsi kunye namandla obushushu esekethe, iintlantsi zombane kunye nefuthe lobushushu eliveliswe ekusebenzeni okuqhelekileyo kunye iimeko ezikhankanyiweyo zeziphene azinako ukuvutha umxube oqhumayo kwindawo engqongileyo, ngaloo ndlela kuzuzwe ukungabikho kokudubula kombane. Isekethe yolu hlobo lwezixhobo zombane ngokwayo inobungqina bokudubula, oko kukuthi, "ngokusisiseko" ikhuselekile, ke ibizwa ngokuba ikhuselekile ngokwangaphakathi (emva koku kubhekiselwa kuyo njengokhuseleko lwangaphakathi). Izixhobo zombane ezisebenzisa iisekethe ezikhuselekileyo zibizwa ngokuba zizixhobo zombane ezikhuselekileyo.
- Uxinzelelo oluhle izixhobo zombane
Umgaqo wobungqina bokuqhuma koxinzelelo olulungileyo lwezixhobo zombane: izixhobo zombane zibekwe kwigobolondo langaphandle, kwaye akukho mthombo wokukhutshwa kwegesi enokutsha kwiqokobhe; iqokobhe lizaliswe yigesi ekhuselayo, kwaye uxinzelelo lwegesi ekhuselayo kwiqokobhe luphezulu kunoxinzelelo lwemekobume engqongileyo eqhumayo, ukuze kuthintelwe umxube oqhumayo wangaphandle ukuba ungangeni kwiqokobhe kwaye uqonde ubungqina bokudubula kombane. izixhobo.
Isimboli yoxinzelelo olulungileyo lwesixhobo sombane ngu "p", kwaye igama elipheleleyo lesimboli ngu "Expl".
- Izixhobo zombane ezizaliswe yintlabathi emigodini
Umgaqo-ubungqina bokuqhuma kwesixhobo sombane esizaliswe yintlabathi: gcwalisa igobolondo langaphandle lesixhobo sombane ngesanti yequartz, ungcwabe iindawo zokuqhuba okanye iindawo eziphilileyo zezixhobo phantsi koqweqwe lwesanti ye-quartz yokuqhuma-ubungqina bokuzalisa, ukuze phantsi kweemeko ezichaziweyo. , i-arc eveliswe kwiqokobhe, idangatye elandiswayo, ubushushu obugqithisiweyo bodonga lweqokobhe langaphandle okanye umphezulu wesanti ye-quartz ayinakuvutha umxube oqhushumbayo ojikelezileyo. Izixhobo zombane ezizaliswe yintlabathi zisetyenziselwa izixhobo zombane ezine-voltage elinganisiweyo engadluli kwi-6kV, iindawo zayo ezihambayo aziqhagamshelani ngokuthe ngqo ne-filler xa zisetyenziswa.
