Lisebelisoa tsa majoe, tse tsejoang hape e le li-jackhammer, ke lithulusi tse matla tse sebelisoang indastering ea kaho, ea merafo le ea ho heletsa.Mechini ena e etselitsoe ho phunyeletsa mafika a thata ka katleho le kapele.Ka tlase, re tla tšohla litšoaneleho, ts'ebeliso le melemo ea li-drill tsa majoe.
Lisebelisoa tsa majoe li na le tsamaiso ea pneumatic kapa hydraulic e fanang ka matla a hlokahalang a ho pshatla majoe.Mochine ona o na le karolo e kang hamore, e bitsoang "drill bit", e otlang holim'a majoe khafetsa ho etsa hore ho robehe.Karolo ea ho phunya e potoloha ha e ntse e otla, e netefatsa ho kenella ka katleho lefikeng.Sebaka sa ho phunya se ka fetoloa ho latela litlhoko tse khethehileng tsa morero.
Mechini ena e sebelisoa haholo-holo mesebetsing ea merafo ho ntša liminerale le tšepe lefatšeng.Ho cheka majoe ho sebelisoa ho etsa lithanele, likoti le likoti merafong e ka tlas'a lefatše.Li boetse li sebelisoa haholo indastering ea kaho bakeng sa ho aha metheo, litsela le marokho.Ho phaella moo, ho phunya majoe ho bohlokoa mosebetsing oa ho heletsa, moo ho sebelisetsoang ho senya mehaho le ho tlosa konkreite.
O mong oa melemo ea bohlokoa ea ho sebelisa li-rock ke bokhoni ba bona le lebelo.Mechini ena e khona ho phunyeletsa mafika a thata ka potlako ho feta mekhoa e tloaelehileng ea matsoho.Sena se boloka nako le mosebetsi, se eketsa tlhahiso libakeng tsa kaho.Ho feta moo, liboro tsa majoe li ka fihla libakeng tseo ho leng thata ho fihla ho tsona, e leng se etsang hore e be tse loketseng lits'ebetso tse fapaneng.
Molemo o mong oa ho phunya rock ke ho feto-fetoha ha tsona.Li ka sebelisoa ka mefuta e fapaneng ea likotoana tsa ho cheka, tse lumellang ho itlhophisa ho ipapisitse le boima ba mafika le litlhoko tsa projeke.Matla le ho nepahala ha liboro tsa majoe li etsa hore li atlehe maemong a fapaneng a jeoloji, ho kenyeletsoa granite, lejoe la mokoetla le konkreite.
Tšireletseho ke karolo ea bohlokoa ha u sebelisa liboro tsa majoe.Basebelisi ba tlameha ho apara lisebelisoa tse nepahetseng tsa ts'ireletso, ho kenyeletsoa likhalase, liatlana, le ts'ireletso ea litsebe, ho thibela likotsi le ho fokotsa ho pepeseha ha lerata.Tlhokomelo le tlhahlobo ea kamehla ea mochini le tsona ke tsa bohlokoa ho netefatsa ts'ebetso e bolokehileng le e nepahetseng.
Qetellong, liboro tsa majoe ke mechini e matla e sebelisoang indastering ea kaho, ea merafo le ea ho heletsa.Li fana ka katleho, lebelo, le ho feto-fetoha ha maemo ho phunyeletsa mafika a thata.Ho utloisisa likarolo le ts'ebeliso ea li-rock ho bohlokoa ho ba sebetsang liindastering tsena.
