【Iimfuno zezixhobo zokomba kwimisebenzi yokwemba umngxuma oqhumayo】
Ukugrumba ngokuqhelekileyo kuchazwa ngeempawu ezine: ukuchaneka, ubunzulu, ukuthe tye kunye nokuzinza.
1.Idamitha yomngxuma
Ubukhulu bomngxuma wokugrumba buxhomekeke kwinjongo esetyenziselwa yona umngxuma.Kwimisebenzi yokugrumba umngxuma wokuqhushumba, kukho izinto ezininzi ezichaphazela ukhetho lwemingxuma.Umzekelo: ubungakanani bamasuntswana amatye afunekayo emva kokuqhekeka kwamatye;uhlobo lokuqhushumba olukhethiweyo;iimfuno "zekhwalithi" zeengqungquthela zamatye eziqhumayo (i-surface smoothness of particles kunye nomlinganiselo wokutyumza);iqondo lokungcangcazela komphezulu okuvunyelweyo kumsebenzi wokuqhushumba, njl.njl.Kwiikwari ezinkulu okanye imigodi emikhulu evulekileyo, ukusetyenziswa kwemisebenzi yokuqhushumba kwemingxuma emikhulu kaninzi kunciphisa iindleko zokomba kunye nokuqhushumba ngetoni nganye yamatye.Kwimisebenzi yokwemba amatye angaphantsi komhlaba, izixhobo zokumbiwa kwemigodi zilinganiselwe yindawo engaphantsi komhlaba.Ekugrunjweni kwemingxuma yamanzi, ubungakanani bomngxuma wamatye buxhomekeke kububanzi bombhobho okanye kwiimfuno zobubanzi bezixhobo ezixhasayo ezifunwa yimpompo yamanzi. , i-diameters ye-bolt rods ezahlukeneyo yimiba yokumisela.
2.Ubunzulu bomngxuma
Ubunzulu bomngxuma buchatshazelwa zizixhobo zokomba zamatye, kwaye izixhobo zokomba ezimfutshane kuphela zinokukhethwa kwindawo elinganiselweyo.Izixhobo zokomba ezimfutshane ngendlela yoqhagamshelo oludityanisiweyo ziyimfuneko kakhulu ekugrunjweni kwamatye kwindawo encinci. Ukuqhushumba kwemingxuma yamatye (imingxuma ethe tye okanye ethe nkqo), ubunzulu bokomba bunzulu kancinci kunobunzulu bethiyori okanye umphakamo weeterraces.Phantsi kweemeko ezithile zokomba amatye, ubunzulu bokomba kufuneka bubenzulu (50-70 yeemitha okanye ubunzulu ).Ngokubanzi, indlela yokomba amatye ye-DTH isetyenziswa endaweni yendlela yokugrumba amatye ngehamile ephezulu.Ukuhanjiswa kwamandla kwindlela yokugaya i-DTH kunye nefuthe lokukhupha umgubo phantsi kweemeko zomngxuma onzulu zisebenza ngakumbi.
3.Ukuthe tye komngxuma
Ukuthe tye komngxuma yinto eyahluka kakhulu kunye nohlobo lwamatye kunye neemeko zendalo, indlela ekhethiweyo yemigodi kunye nezixhobo ezikhethiweyo zokumbiwa. .Xa kugrunjwa umngxuma onzulu wokuqhushumba, umngxuma wamatye owombiweyo kufuneka uthe tye kangangoko ukuze intlawulo ifumane ngokuchanekileyo isiphumo esifanelekileyo sokuqhushumba.
Kwezinye iindidi zemisebenzi yokugrumba amatye, kuye kufuneke ukugrumba imingxuma enzulu yamatye, kwaye ukuthe tye kwemingxuma yamatye kufuna kakhulu, njengemingxuma yemibhobho okanye imingxuma yentambo. imibhobho kunye neempompo zinokufakwa kakuhle.
Ukusetyenziswa kweentlobo ezahlukeneyo zezixhobo zesikhokelo, njengeentloko zokuqhuba isikhokelo, isikhokelo sokubhobhoza imibhobho kunye nemibhobho yokuqhubela isikhokelo, kuya kuphucula ukuthe tye komngxuma. izinto ezifana neqondo lohlengahlengiso lwe-propulsion beam kunye nokuchaneka kokuvula.Ngoko ke, ukuchaneka okubonakalayo kuyafuneka kulo mba.Uphononongo lubonise ukuba ngaphezu kwe-50% ye-rock hole offset ngenxa yokulungelelaniswa kwe-propulsion engafanelekanga kunye nokungahambi kakuhle. ukuvula.
4.Ukuzinza komngxuma
Enye imfuneko yomngxuma wamatye ombiweyo kukuhlala uzinzile de ube uhlawuliswe okanye usetyenziswe kwezinye iinjongo.Phantsi kweemeko ezithile, njengaxa kusomba izinto ezixengayo okanye iindawo zamatye athambileyo (indawo ithanda ukuthotywa nokuvala imingxuma yamatye), kubaluleke kakhulu ukusebenzisa umbhobho wokubhola okanye umbhobho ukuhla kumngxuma wamatye owombiweyo.
