【Izimfuneko zamathuluzi okumba emisebenzini yokumba imigodi eqhumayo】
Ukubhoboza ngokuvamile kuchazwa izici ezine: ukuqondisa, ukujula, ukuqondisa nokuzinza.
1.I-diameter yembobo
Ububanzi bembobo yokubhoboza buncike enjongweni okusetshenziselwe yona imbobo.Emisebenzini yokumba imbobo yokuqhuma, kunezici eziningi ezithinta ukukhethwa kwemigodi.Isibonelo: ubukhulu bezinhlayiya zamadwala ezidingekayo ngemva kokuphuka kwamatshe;uhlobo lokuqhumisa olukhethiwe;izidingo "zekhwalithi" zezinhlayiya zamadwala eziqhumayo (ubushelelezi obuphezulu bezinhlayiya kanye nenani lokuchotshozwa);izinga lokudlidliza komhlaba elivunyelwe ekusebenzeni kokuqhuma, njll.Ezinkwalini ezinkulu noma ezimayini ezinkulu ezivulekile, ukusetshenziswa kokuqhuma kwembobo enkulu kuvame ukwehlisa izindleko zokumba nokuqhunyiswa ngethani ngalinye ledwala.Emisebenzini yokumba amatshe angaphansi komhlaba, impahla yezimayini inqunyelwe indawo engaphansi komhlaba.Ekumbiweni kwemigodi yemithombo yamanzi, ubukhulu bembobo yedwala buncike kububanzi bepayipi noma izidingo zobubanzi bempahla esekelayo edingwa yiphampu yamanzi.Ngokwezimbobo zokusekela ukwakheka kwamadwala , ububanzi bezinduku ze-bolt ezihlukene yizici ezinqumayo.
2.Ukujula komgodi
Ukujula komgodi kuthintwa imishini yokumba amatshe, futhi amathuluzi okumba amafushane kuphela angakhethwa endaweni elinganiselwe.Amathuluzi okumba amafushane ngendlela yokuxhuma okunentambo adingeka kakhulu ekubholeni amatshe endaweni elinganiselwe.Emisebenzini yokumba amatshe ezimbotsheni zamatshe aqhumayo (imigodi evundlile noma eqondile), ukujula kokumba kujule kancane kunokujula okucatshangelwayo noma ukuphakama kwamasimu.Ngaphansi kwezinye izimo zokumba amatshe, ukujula kokumba kuyadingeka ukuthi kujule (amamitha angama-50-70 noma ukujula. ).Ngokuvamile, kusetshenziswa indlela ye-DTH yokumba amatshe esikhundleni sendlela yokumba idwala ephezulu ngesando.Ukudluliswa kwamandla endlela ye-DTH yokumba amatshe kanye nomphumela wokukhipha impushana ngaphansi kwezimo zembobo ejulile kusebenza kahle kakhulu.
3.Ukuqondisa komgodi
Ukuqondisa komgodi kuyisici esihluka kakhulu ngohlobo lwedwala nezimo zemvelo, indlela yezimayini ekhethiwe kanye nemishini yezimayini ekhethiwe.Ekubholeni kwamadwala okuvundlile nokuthambekele, isisindo sethuluzi lokubhoboza sizophinde sithinte i-offset yomgodi. .Lapho umba imbobo ejulile yokuqhuma, imbobo yetshe elibhoboziwe kufanele iqonde ngangokunokwenzeka ukuze ukushaja kukwazi ukuthola umphumela ofanele wokuqhumisa.
Kwezinye izinhlobo zemisebenzi yokumba amadwala, ngokuvamile kuyadingeka ukubhoboza izimbobo zamatshe ezijulile, futhi ubuqotho bemigodi yamadwala bufuna kakhulu, njengezimbobo zamapayipi noma izimbobo zamakhebula.Ngisho nezidingo zemigodi yemithombo yamanzi ziqinile kakhulu ukuze amanzi amapayipi namaphampu angafakwa kahle.
Ukusetshenziswa kwezinhlobo ezahlukene zemishini yokuqondisa, njengamakhanda okubhoboza umhlahlandlela, amapayipi okubhola aqondisayo kanye namapayipi okubhola aqondisayo, kuzothuthukisa ukuqondisa kwembobo.Ngaphezu kokusuka komgodi wedwala ngokwawo, isiqondiso sokubhola sihlobene futhi izici ezifana nezinga lokulungiswa kwe-propulsion beam kanye nokunemba kokuvula.Ngakho-ke, ukunemba okukhulu kuyadingeka mayelana nalokhu.Ucwaningo lubonise ukuthi ngaphezu kuka-50% we-rock hole offset kungenxa yokulungiswa okungenangqondo kwe-propulsion beam kanye nokubi. ukuvula.
4.Ukuzinza kwezimbobo
Enye imfuneko yembobo yamatshe ebhoboziwe iwukuhlala uzinzile ize ikhokhiswe noma isetshenziselwe ezinye izinjongo.Ngaphansi kwezimo ezithile, njengalapho kubholwa izinto ezixegayo noma izindawo zamadwala athambile (indawo inomkhuba wokwehlisa izinga kanye nokuvala izimbobo zamadwala), kubaluleke kakhulu ukusebenzisa ipayipi lokubhoboza noma ipayipi ukuze wehlele phansi emgodini wetshe elibhoboziwe.
