Iimpawu zokwakheka kwamatye aqinileyo njengegranite kunye nomngcipheko wokwakheka kwemingxunya. Xa kusenziwa iziseko zeepali zeebhulorho ezinkulu ezininzi, iipali kufuneka zingene kwilitye eliqinileyo eligugileyo ukuya kubunzulu obuthile, kwaye ububanzi beepali ezenzelwe ezi ziseko zeepali bungaphezulu kwe-1.5mm. Nokuba yi-2m. Ukugrumba kwiindawo ezinjalo ezinkulu zelitye eliqinileyo kubeka iimfuno eziphezulu kumandla kunye noxinzelelo lwezixhobo, ngokubanzi kufuna i-torque engaphezulu kwezixhobo ezingama-280kN.m. Xa kugrunjwa kolu hlobo lokwakheka, ukulahleka kwamazinyo okugrumba kukhulu kakhulu, kwaye iimfuno eziphezulu zibekwe kukumelana nokungcangcazela kwezixhobo.
Indlela yokwakha yokubhoboza ejikelezayo isetyenziswa kwiindawo eziqinileyo zamatye anjengegranite kunye nesanti. Amanyathelo kufuneka athathwe kwezi ngongoma zilandelayo ukuphucula ukusebenza kakuhle kokwenza umngxuma kunye nokunciphisa iingozi.
(1) Izixhobo ezinamandla angama-280kN.m nangaphezulu mazikhethwe ukuze kusetyenziswe ukugrumba. Lungisa amazinyo okugrumba anobunzima obuphezulu kunye nokusebenza ngcono kokugrumba kwangaphambili. Amanzi kufuneka ongezwe kwiindawo ezingenanto yokusetyenziswa ukuze kuncitshiswe ukuguguleka kwamazinyo okugrumba.
(2) Cwangcisa izixhobo zokubhola ngokuchanekileyo. Xa kugrunjwa imingxunya yeenqwaba ezinkulu ngolu hlobo lokwakheka, kufuneka kukhethwe indlela yokugrunjwa ehleliweyo. Kwinqanaba lokuqala, kufuneka kukhethwe i-barrel drill ende enobubanzi obuyi-600mm ~ 800mm ukuze kukhutshwe ngqo umbindi kwaye kwenziwe ubuso obukhululekileyo; okanye kufuneka kukhethwe i-spiral drill encinci enobubanzi ukuze kugrunjwe ukwenza ubuso obukhululekileyo.
(3) Xa kuvela imingxunya etyekileyo kwiindawo eziqinileyo zamatye, kunzima kakhulu ukutshayela imingxunya. Ke ngoko, xa udibana nomphezulu welitye otyekileyo, kufuneka ulungiswe ngaphambi kokuba ukubhola kuqhubeke ngokwesiqhelo.
