Izigaba kanye Nezimiso Zokusebenza Zemishini Yokubhola Amadwala

Imishini yokumba amadwala, eyaziwa nangokuthi ama-rock drill noma ama-rock breaker, ingamathuluzi abalulekile asetshenziswa ezimbonini ezihlukahlukene ezifana nezimayini, ezokwakha, nokuhlola.Lesi sihloko sihlose ukuhlinzeka ngemininingwane yezigaba eziyisisekelo nezimiso zokusebenza zemishini yokumba amatshe.

I. Ukuhlelwa Kwemishini Yokumba Amadwala:

1. I-Rock Drill ebanjwa ngesandla:
- I-Pneumatic Hand-held Rock Drills: Lezi zimbobo zinikwa amandla ngomoya ocindezelwe futhi zivame ukusetshenziselwa imisebenzi yokumba encane.
- I-Electric Hand-held Rock Drills: Lezi zimbobo zisebenza ngogesi futhi zilungele ukubhoboza endlini noma izindawo ezingenawo umoya omncane.

2. I-Mounted Rock Drills:
- I-Pneumatic Mounted Rock Drills: Lezi zimbobo zifakwa emshinini noma endaweni yesikhulumi futhi zivame ukusetshenziswa ezimayini nasezindaweni ezinkulu zokwakha.
- I-Hydraulic Mounted Rock Drills: Lezi zimbobo zinikwa amandla amasistimu asebenza ngaphansi kwamanzi futhi aziwa ngokusebenza kwawo okuphakeme nokuguquguquka.

II.Izimiso Zokusebenza Zemishini Yokubhola Amadwala:
1. Ukushayela Ngokushaywayo:
- I-Percussion drilling iyindlela evamile yokumba esetshenziswa emishinini yokumba amadwala.
- I-drill bit ishaya i-rock surface ngokuphindaphindiwe nge-frequency ephezulu, idala ukuphuka nokukhipha izinhlayiya zamadwala.
- I-drill bit inamathiselwe ku-piston noma isando esikhuphuka sikhuphuke ngokushesha, esiletha amandla okuthonya endaweni yedwala.

2. Ukubhola Okujikelezayo:
- I-Rotary drilling isetshenziswa lapho kubhobozwa amatshe aqinile.
- I-drill bit iyazungeza ngenkathi icindezela phansi, igaya futhi iqhekeza idwala.
- Le ndlela ivame ukusetshenziswa emisebenzini yokumba ejulile, njengokuhlola uwoyela negesi.

3. Ukumba Phansi Komgodi (DTH):
- Ukubhoboza i-DTH kuwukwehluka kokumba nge-percussion.
- I-drill bit ixhunywe kuntambo yokubhoboza, bese yehliselwa emgodini.
- Umoya ocindezelwe uphoqeleka phansi entanjeni yokubhoboza, ubambe iqhaza ekubhoboleni bese uhlephula idwala.

Imishini yokumba amadwala idlala indima ebalulekile ezimbonini ezihlukahlukene, ivumela ukusebenza kahle nokunemba komsebenzi wokumba.Ukuqonda izigaba eziyisisekelo kanye nezimiso zokusebenza zale mishini kubalulekile ekukhetheni okokusebenza okufanele kwezinhlelo zokusebenza ezithile.Kungakhathaliseki ukuthi ibanjwa ngesandla noma ifakwe emanzini, inikwa amandla ngomoya, ugesi, noma ama-hydraulic, imishini yokumba amadwala iyaqhubeka nokuthuthuka ukuze ihlangabezane nezidingo zezimboni zesimanje.
