Yiziphi izigaba zamapayipi ezisetshenziswa kakhulu?
Ukuze kusetshenziswe ipayipi lerabha, ukunikezwa kuyashoda embonini.Inketho yokuqala i-hose yerabha enengcindezi ephezulu enocingo lwensimbi iyona esetshenziswa kakhulu.Ngenxa yokucindezela okuhle nokumelana nowoyela, isetshenziswa ekuxhumekeni kwemishini, imishini yokwakha, ama-hydraulic props, njll. Ukucindezela okukhulu kufinyelela ku-70Mpa.
Ku-hose yerabha enendwangu, ububanzi bamanzi bubanzi.Amanzi ezimbonini, udaka, uwoyela we-hydraulic, uwoyela we-emulsified, amanzi ashisayo nesitimu singasetshenziswa.
I-hose yerabha enobubanzi obukhulu, izingqimba ezi-6 zesemishi lezintambo ungqimba locingo lwensimbi oluvunguzayo, ngaphansi kwesimo sokucindezela okungekuhle,
Imikhiqizo ethunyelwa kakhulu kwamanye amazwe amapayipi enjoloba alukiwe ngensimbi kanye namapayipi enjoloba ajwayelekile, kuyilapho ukuthunyelwa kwamanye amazwe kwamapayipi enjoloba yezimoto anokuqukethwe okuphezulu kobuchwepheshe kuncane.Phakathi kwamapayipi, amapayipi asonga intambo yamakhemikhali, amapayipi alukiwe, amapayipi alukiwe, amapayipi alukwe ngocingo lwensimbi, amapayipi asongayo kanye namapayipi ensimbi enza ngaphezu kuka-60%, nakho okuseduze nezinga eliphezulu lamazwe ngamazwe.Ngenxa yokuthi ukwakheka komkhiqizo kuhambisana nezindinganiso zamazwe ngamazwe, kulungele ukuthunyelwa kwamanye amazwe imikhiqizo yepayipi lerabha ezweni lami.
Umthamo wokukhiqiza wemikhiqizo yamashubhu erabha eyinhloko ubalwa phakathi kwezihamba phambili emhlabeni.Nakuba imikhiqizo yepayipi lerabha yezwe lami inezimo eziyisisekelo zenani elikhulu lokuthunyelwa ngaphandle, umthamo wangempela wokuthekelisa usemncane.Ngokwezibalo zeNational Bureau of Statistics, eminyakeni yamuva nje, inani lonyaka lokuthekelisa lamashubhu enjoloba libalele kuphela ngaphansi kwe-1% yenani eliphelele lonyaka lokuthekelisa lemikhiqizo yenjoloba, u-9.5% yenani lonyaka lokuthekelisa lamathayi, kanye I-1.4% yenani lokuthekelisa lonyaka lezicathulo zenjoloba.Ngaphezu kwalokho, kulinganiselwa ukuthi inani lokuthekelisa lemikhiqizo yepayipi lenjoloba yezwe lami libalelwa ku-10% yenani eliphelele lokukhishwayo.
