Kwinkqubo yokwakhiwa kweziseko ezingundoqo kunye nokumbiwa kwemigodi ephantsi komhlaba, kuyimfuneko ukugrumba amaqula amaninzi kunye neendlela zokwenza inkqubo yophuhliso kunye nokuqhuba imigodi, ukusika, kunye nokubuyisela.Xa kugrunjwa imingxuma, ukwenzela ukungxengxeza nokukhupha uthuli lwentsimbi ekrwada oluveliswe ngexesha lenkqubo yokugrumba kunye nomoya ongcolisekileyo onjengomsi wompu oveliswe emva koqhushumbo, ukudala iimeko ezintle zemozulu yasemgodini, kunye nokuqinisekisa ukhuseleko kunye nempilo yabasebenzi, umoya oqhubekayo wendawo. ubuso bokuqhuba bufuneka.Ukusetyenziswa komoya wendawo ekuphuculeni umgangatho womoya wobuso obusebenzayo kuxhaphake kakhulu.Ngokuqhelekileyo imeko yokuphuma komoya yendlela enentloko enye imbi kakhulu, kwaye ingxaki yokuphuma komoya ayisonjululwanga kakuhle.Ngokwamava ahambele phambili emigodini, isitshixo sesokuba ingaba i-diameter ye-ventilation duct efanelekileyo isetyenziswa kwindawo yokungena komoya yendawo, kwaye isitshixo sokuba i-diameter ye-ventilation duct efanelekileyo ingasetyenziswa ixhomekeke kubukhulu becandelo lendlela enentloko enye. .Kweli phepha, i-formula yokubala yobubanzi bombhobho wokungenisa umoya wezoqoqosho ifunyenwe ngophando.Umzekelo, ubuso obuninzi bokusebenza kumgodi we-Fankou lead-zinc zisebenzisa oomatshini bedizili kunye nezixhobo ezinkulu, kwaye indawo enqamlezileyo yendlela inkulu.
Ngokweencwadi ezifanelekileyo malunga nokungena komoya osemgodini, imigaqo jikelele yokukhetha ububanzi bemibhobho yokungenisa umoya yasekhaya yile: Xa umgama wonikezelo komoya ungaphakathi kwe-200m kwaye umthamo wonikezelo komoya ungekho ngaphezulu kwe-2-3m.3/s, ububanzi bombhobho wokungenisa umoya osemgodini kufuneka bube yi-300-400mm; Xa umgama wonikezelo komoya uyi-200-500m, ububanzi bombhobho wokungenisa umoya osemgodini yi-400-500mm; Xa umgama wobonelelo lomoya uyi-500-1000m, Idayamitha yombhobho wokungenisa umoya osemgodini yi-500-600mm;Ngaphezu koko, uninzi lwabavelisi bemibhobho yokungenisa umoya emigodini bachaza iimveliso zabo kolu luhlu.Ke ngoko, i-diameter ye-mining ventilation ducting esetyenziswa kwimigodi yesinyithi kunye ne-non-metal engaphantsi komhlaba e-China ngokusisiseko ibikuluhlu lwe-300-600mm ixesha elide.Nangona kunjalo, kwimigodi yangaphandle, ngenxa yokusetyenziswa kwezixhobo ezinkulu, indawo enqamlezileyo yendlela inkulu, kwaye ububanzi bemibhobho ye-ventilation yendawo yemigodi idla ngokuba nkulu, enye ifikelela kwi-1500 mm, kunye nobubanzi bombhobho. Imibhobho yokuphefumla yomgodi wesebe ingaphezulu kwe-600 mm.
Kweli phepha, ifomyula yokubala yobubanzi bombhobho wokungenisa umoya womgodi wezoqoqosho iphononongwa phantsi kwezona meko zincinci zoqoqosho zeendleko zokuthengwa kwemibhobho yokuvula imigodi yemigodi, ukusetyenziswa kombane wokungena komoya wendawo ngombhobho wemigodi yemigodi, kunye nofakelo lwemihla ngemihla. kunye nokugcinwa kwemibhobho yemigodi yemigodi.Ukungena komoya wendawo kunye nedayamitha yokungenisa umoya enoqoqosho inokufikelela kwisiphumo esingcono sokungenisa umoya.
Iza kuqhubeka…
