Ukukhethwa kobubanzi bombhobho wokungena umoya womgodi wasekhaya (1)

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 ukumba i-shafts, ukwenzela ukuhlanjululwa kunye nokukhupha uthuli lwe-ore oluveliswe ngexesha lenkqubo yokwemba kunye nomoya ongcolileyo onjengomsi wompu owenziwe emva kokuqhuma, ukudala iimeko ezintle zemozulu zemigodi, kunye nokuqinisekisa ukhuseleko kunye nempilo yabasebenzi, umoya oqhubekayo wendawo wokuqhuba ubuso obufunekayo. 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 yangaphandle, isitshixo kukuba ingaba i-diameter ye-ventilation duct efanelekileyo isetyenziswa kwindawo yokungena komoya yendawo, kwaye isitshixo sokuba i-diameter ye-ventilation duct efanelekileyo ingasetyenziselwa kuxhomekeke kubukhulu becandelo lendlela 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 womgodi yi-400-500mm; I-1000m, ububanzi bombhobho wokungena umoya womgodi kufuneka ube yi-600-800mm. 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 yendlela inkulu, kwaye ububanzi bemibhobho ye-ventilation yendawo yemigodi idla ngokuba nkulu, ezinye zifikelela kwi-1500 mm, kunye nobubanzi bemibhobho ye-ventilation yesebe ngokubanzi ngaphezu kwe-600 mm.

Kweli phepha, ifomyula yokubala yobubanzi bombhobho wokungenisa umoya womgodi wezoqoqosho iphononongwa phantsi kweemeko zoqoqosho ezincinci zeendleko zokuthengwa kwemibhobho yokuvula imigodi, ukusetyenziswa kombane wokungena komoya wendawo ngokusebenzisa umbhobho wokuvula imigodi, kunye nokufakelwa kwansuku zonke kunye nokugcinwa kwemigodi yemigodi yemigodi. Ukungena komoya wendawo kunye nedayamitha yokungenisa umoya enoqoqosho inokufikelela kwisiphumo esingcono sokungenisa umoya.

Iza kuqhubeka…
