Iziphumo ezithojwe ukuvimbela ukuxhumana kwezinsimbi zibalulekile ezindaweni zokukhiqiza ikhatshana, zenzelwe ukuvimbela ukuphahlazeka okukhulu ngenxa yezigameko ezinhlelayo. Le ndatshana ihlola imibono yokwakha, izingxenye, kanye nemisebenzi yeziphumo ezithojwe ukuvimbela, eziqondiswe ngok khusus ezindaweni zokukhiqiza ikhatshana.
Amamitha wama-coal abalulekile ekukhiqizeni amandla ezikhumulweni zamandla ezisebenzisa amakholi. Nokho, azibangalela izingozi ezinkulu ngenxa yokwenzeka kokuxubha okungaba khona phakathi kw dust ne air. Izivalo ezivikelekile emandleni okushaya zenzelwe ukunciphisa lezi zingozi ngokulawula nokuphendula amandla aphakathi okukhukhuleka.
Ukuklama kwemigomo yokuvikela ukuvutha kuma-mills wamalahle kukhuthazwa yizimiso eziningi ezibalulekile:
Ithuluzi lokuvikela ukuvulwa kutholakala ngezinto eziningi ezibalulekile:
Ngesikhathi sokusebenza okujwayelekile, ivali le-explosion proof lihlala livaliwe, ligcina ukuvimbela kwe-air-tight ukuvimbela ukuphuma kokungcebeleka kwekhola. Uhlelo lokuvikela lwevali luqinisekisa ukuthi umshini usebenza kahle ngaphandle kokulahlekelwa kwemathirial.
Uma kwenzeka ukush explosiv, uhlelo lokusebenza lwe-valve luthola ukwanda okusheshayo kwengcindezi. Ukuvuleka kwengcindezi kubangelwa, kuholela ekutheni i-valve ivuleke ngokushesha. Le nhloso ivumela ukuba amagesi aphumile kahle, unciphisa ingozi yokulimala kwemishini nendawo ezungezile.
Kunezici eziningi okufanele zicatshangelwe uma kukhulunywa ngokuqamba ama-valve angavuleki ezikhukhulweni zokushisa zamalahle:
Ukuhlinzekwa kahle nokugcinwa njalo kubalulekile ukuze izivala zokukhukhuleka zisebenze kahle.
– Qinisekisa ukuhlinzekwa okufanele kanye nezinhlelo zomshini.
– Qinisekisa ukuhlela kokuhlola ukuze kutholakale ingcindezi enembile.
– Hlola umzimba we-valve ngezimpawu zokugqoka noma damage.
– Bheka umsebenzi wesistimu yokuvula njalo.
– Shintsha amasango nezinye izingxenye njengoba kudingeka ukuze kugcinwe ubuqotho obungangeni bumnene.
Amavaluva aphephile ekuqhumeni abalulekile emashalofini wamakoloni, aklanyelwe ukuvikela ngaphambi kwezingozi zokuhlangana komoya nedust eshisa. Ngokuqonda ukuklama kwabo, ukusebenza, nezidingo zokugcinwa, abasebenzi bangaqinisekisa ukusebenza okuphephile nokusebenza kahle kwemashalofu. Amavaluva aphephile ekuqhumeni aklanyisiwe kahle futhi agcinwe ngokufanele anciphisa kakhulu ingozi yokwehluleka okubuhlungu, evikela futhi abantu nabathengi.
