I-SWMC Yethule Iphakethe Lesixazululo se-BEIFANG QUARRY

I-SWMC, umkhiqizi woMshini wokubhola, ngendlela efanayo yokuhlinzeka ngemikhiqizo ephelele yemishini yamakhasimende, isebenzisa iminyaka engaphezu kwengu-20 yesipiliyoni somkhakha ukuhlinzeka ngezixazululo ezinokwethenjelwa zabasebenzisi bemishini yokubhoboza ingaphansi komhlaba nokusiza insizakalo yamakhasimende ukufeza izinjongo zobunjiniyela nge izindleko eziphansi nokusebenza kahle okuphezulu.Kubikwa ukuthi ukusebenzisana phakathi kwenkampani ye-Xuanhua yokumba imishini ye-SWMC ne-BEIFANG akugcini ekunikezeni izinsiza kusebenza.Lapho inkwali ye-BEIFANG yayidinga izinto eziphuthumayo, i-SWMC iphinde inikeze insizakalo yokuqashisa i-X5A-DTH. Inkwali ye-BEIFANG ibingadingi ukuthi itshale imali eningi, ebisonga izindleko zokukhiqiza futhi yehlise ubungozi bokufaka. Umshini wokubhola we-SWMC ungaqonda kangcono izidingo zenkwali ye-BEIFANG futhi unikeze izixazululo ezibalulekile zentuthuko yayo yangomuso.

I-SWMC ihlinzeka ubuchwepheshe bokubhola ku-BEIFANG Quarry, etholakala eChaoyang edolobheni, esifundazweni saseLiaoning, ukuyisiza ithuthukise ukusebenza kahle kokuqhumisa.

I-tuff etholakala enkwalini ye-BEIFANG yetshe le-sandstone elisezingeni eliphakeme kakhulu.Lenkwali ihlela ukumba amatshe angaba ama-cubic metres ayizigidi ezi-3 lapha minyaka yonke.

Singacabanga ukuthi uma sibhoboza umgodi ngobunzulu obungu-22m nobubanzi obuyi-115mm ngesando, kuzoba nokuthambekela okusobala nokusebenza kahle kokubhola kuzokwehla.Ngakho-ke, inkwali ye-BEIFANG ithenge amasethi ama-2 e-SWMC X5A-DTH egcwele amanzi acwilayo umshini owenziwe yi-SWMC. Ingasebenza ngezifutho ezingena ngaphansi kwengcindezi ephezulu, kanti ingcindezi yokusebenza ifinyelela ku-21bar.

Ubulukhuni bedwala ubunzima obuphakathi F = 8-10. Ngemuva kokuhlolwa okuphindiwe enkwalini, kuthathwe isinqumo sokwamukela inqubo yemigodi ethambekile ngembobo ye-140mm kanye ne-Angle yama-degree angama-30 ukusuka ohlangothini oluqondile. Ngale ndlela, ukuzinza kwesinyathelo kungaba ngcono, ulayini wokumelana ungafana, futhi iphesenti lenqwaba nezinsalela kungancishiswa.

I-X5A-DTH eyenziwe nguTaiye, umkhiqizi wokumba imishini eXuanhua, isetshenziselwa ukwenza ngcono ukusebenza kahle.I-BEIFANG ikhethe le drill ngoba ingalawula ngokunembile i-Angle yokumba, ihlanze imbobo futhi ibushelele udonga lomgodi, ibhoboze imbobo ejulile futhi ibhoboze ngokushesha.

Inkwali ye-BEIFANG ibeka phambili izidingo ezikhethekile zokukhiqiza kahle. Sivame ukuthi, "ngcono ikhwalithi yokwakheka kwemigodi, ngcono ukuqhuma, futhi-ke, imiphumela iba ngcono. Ngamanye amagama, ukunciphisa inani lokuqhumisa kwesibili kungakhuphula umkhiqizo.

I-X5A-DTH drill rig ukusebenza ngokuzimela ngokuphelele kwe-rig, ifakwe okusetshenzisiwe kumfutho womoya ophakeme we-DTH impacter wokumba imoto yomoya compressor, unikele ngenkwali ye-BEIFANG umshini o-2 ojwayelekile ngokuphelele, ngoba izimbobo ezithambekele, ngakho-ke udinga ukwakheka okukhethekile kwerabha ikhava yothuli, futhi ngenxa yedwala eliqinile, i-drill idinga izilungiselelo ezithile zepharamitha.

Isibonelo, ukwakheka kokuma komhlaba kwenkwali kudinga ukukhethwa kwesivinini esisheshayo ngamazinyo ekholomu noma inhlanganisela yamazinyo ekholomu namazinyo entwasahlobo.Ibhola lokuprakthiza lizungeza phakathi kokuzungeza okungama-70 kuya kwangama-80 ngomzuzu, nezimbobo zamadwala ezingabonakali ngaphansi kobuso kungadala ukuthi izimbobo zehluleke ukwakheka, noma intambo yokubhoboza ibhajwa emgodini, noma ingcindezi iyawa.

Ngokuphathelene nokusebenza kahle kokukhiqizwa, kwemigodi engama-22 metres ukujula, isikhathi sokubhola sincishisiwe sisuka emgodini owodwa nge-45min kuya kwesilinganiso se-1 hole nge-30min.
