Ukuza kuthi ga ngo-2020.12.5, kubekho ukufa kwabantu abayi-122 kwimigodi yamalahle kulo lonke ilizwe kulo nyaka, okubulala okanye ukubamba abantu abayi-224. Kulo nyaka, iingozi ezinkulu zokhuseleko kwimigodi yamalahle (xa kuthelekiswa no-2019) zinyuke nge-1, kwaye inani lokufa linyuke ngabantu abayi-16, ukunyuka kwe-50% kunye ne-44% ngokulandelelana." Ingozi yomlilo yaseChongqing Songzao "9.27", abantu abayi-16 bafa kwaye abantu abangama-38 benzakala; Ingozi yomlilo yaseChongqing Songzao "9.27" ibangele ukufa kwabantu abangama-23. Ubomi obuninzi obutsha bumisiwe phantsi komgodi wamalahle. Ngelixa siwugxeka, ukhuseleko lokusebenza kwemigodi yamalahle kufuneka luvuselele ingqalelo yabantu kwaye luvuse intsimbi yesilumkiso emazantsi entliziyo yam.
Emva kohlalutyo olusisiseko, isizathu sengozi yomlilo iChongqing Songzao "9.27" yi-Downhole No. 2 large dip, ukuguguleka okukhulu kwebhanti yamalahle. Emva kokuba ubushushu bebhanti bunyukile. Ngenxa yokungasebenzi kakuhle kwesixhobo sokukhusela ubushushu kunye nesixhobo sokubona umsi esifakwe kwi-conveyor yebhanti, akukho silumkiso okanye ukuyeka ukusebenza kwebhanti. Kwabangela ukuba ibhanti ibambe umlilo kwaye kwabangela ukuba amalahle akwibhanti atshise. Iigesi ezinobuthi neziyingozi eziveliswa kukutsha ziya kubuya kwindawo yokusebenza, zibangele ityhefu kubasebenzi.
Imithetho yokhuseleko lwemigodi yamalahle imisela ukuba uxinaniso lwe-carbon monoxide emoyeni kwimigodi yamalahle mayingadluli kwi-0.0024%, kwaye i-carbon monoxide iya kuveliswa xa imithungo yamalahle itsha ngokuzenzekelayo okanye xa kuvela umlilo ongaphantsi komhlaba. Sonke siyazi ukuba ubuthi be-carbon monoxide buyingozi kakhulu. Emva kokuba i-carbon monoxide iphefumlelwe emzimbeni womntu, iya kudibana ne-hemoglobin emzimbeni womntu, ize emva koko yenze i-carboxyhemoglobin. Ingenza i-hemoglobin emzimbeni womntu ilahlekelwe ngumsebenzi kunye nomsebenzi wokuthwala ioksijini, ngaloo ndlela inokubangela i-hypoxia kunye ne-asphyxia. Iingozi ezininzi zemigodi yamalahle ikakhulu zibangelwa kukuveliswa okanye ukuvuza kweegesi ezinobuthi ezifana ne-carbon monoxide okubangele ityhefu yabasebenzi kunye neengozi ezibulalayo. Ke ngoko, ekuhlolweni kwethu kokhuseleko lwemihla ngemihla, kufuneka sinikele ingqalelo ekhethekileyo ekusebenzeni okuqhelekileyo kunye nokusebenza kwee-alamu zomsi, ii-alamu ze-carbon monoxide kunye nezinye izixhobo ukubonelela ngesiqinisekiso sokhuseleko lwethu.
I-alamu ye-HENGKO fixed co sisixhobo sokufumanisa i-co, sinenzuzo yokuphendula ngokukhawuleza, uvakalelo oluphezulu, amandla okulwa nokuphazamiseka okunamandla kunye nokukhusela kwinqanaba le-IP65. Xa uxinzelelo lwe-carbon monoxide ludlula ixabiso elimiselweyo lesixhobo, i-detector iya kuthumela ngoko nangoko isignali ye-alamu evakalayo nebonakalayo.
Imodyuli yesenzwa ye-HENGKO CO yimodyuli yegesi yendalo yonke eyilwe kwaye yenziwa ngokudibanisa iteknoloji yokufumanisa i-electrochemical eyinkimbinkimbi kunye nesekethe eyinkimbinkimbi. Eli candelo lisebenza nesekethe yokuqhuba elula, enemveliso yedijithali kunye nemveliso ye-analog voltage, uzinzo oluhle kunye nobomi obude. Isiphumo sokulinganisa singafundwa kwi-microprocessor ngokusebenzisa ujongano lwe-I2C lomsebenzisi.
Ukongeza kwi-alamu ye-carbon monoxide esisigxina, i-HENGKO ikwanayo ne-alamuisixhobo sokubona igesi esiphathwayo esiphathwayoenokusoloko ibona uxinano lwegesi enye. Isixhobo sokubona sisebenzisa isampuli yepompo ukuze sibone igesi, kwaye umsebenzisi angakhetha intonga efanelekileyo ngokweemfuno ezahlukeneyo zokusingqongileyo, nto leyo eyenza umlinganiselo ube lula ngakumbi. Isixhobo sokubona sisebenzisa isibonisi se-OLED dot matrix esikhulu, esibonisa ngokubonakalayo uxinano, uluhlu kunye nexesha langoku legesi elinganiswayo. Imo yokusebenza elula enezitshixo ezintathu kunye nomyalezo wolwazi oluneenkcukacha zenza umsebenzi ube mfutshane kwaye kube lula ukuwuqonda.
