Izimayini ezingaphansi komhlaba
Uma idiphozi igqitshwa phansi ngezansi kwendawo, i-coefficient yokuhlubula izoba phezulu kakhulu uma kwamukelwa imayini yomgodi ovulekile.Ngenxa yokuthi umzimba we-ore ungcwatshwe ngokujulile, ukuze kukhishwe i-ore, kuyadingeka ukumba umgwaqo oholela emzimbeni we-ore ukusuka phezulu, njenge-shaft eqondile, i-inclined shaft, i-slope road, i-drift nokunye.Iphuzu elibalulekile lokwakhiwa kwezimali zezimayini ngaphansi komhlaba ukumba le miklamo yemithombo kanye nomzila.Izimayini ezingaphansi komhlaba ikakhulukazi zihlanganisa ukuvula, ukusika (umsebenzi wokuhlola nokusika) kanye nokumba.
Indlela yezimayini yokwesekwa kwemvelo.
Indlela yezimayini yokwesekwa kwemvelo.Lapho ubuyela ekamelweni lezimayini, indawo enemigodi eyakhiwe isekelwe izinsika.Ngakho-ke, isimo esiyisisekelo sokusetshenziswa kwalolu hlobo lwendlela yezimayini ukuthi i-ore nedwala elizungezile kufanele lizinzile.
Indlela yezimayini yokusekela ngesandla.
Endaweni yezimayini, ngokuthuthuka kobuso bezimayini, indlela yokweseka yokwenziwa isetshenziselwa ukunakekela indawo embiwe futhi kwakhiwe indawo yokusebenza.
Indlela ye-Caving.
Kuyindlela yokulawula nokuphatha ukucindezela komhlaba ngokugcwalisa i-goaf nge-caving rock.I-Surface caving iyimfuneko edingekayo ukuze kusetshenziswe lolu hlobo lwendlela yezimayini ngoba ukugenca kwamadwala odonga olungenhla nangaphansi kuzodala ukugezeka komhlaba.
Ukumba izimayini ezingaphansi komhlaba, noma ngabe ukuxhashazwa, ukumba izimayini noma ukumba izimayini, ngokuvamile kudinga ukubhobozwa, ukuqhunyiswa, ukungena komoya, ukulayisha, ukusekela nokuthutha nezinye izinqubo.
