1. Pob zeb xyaum
Pob zeb xyaum yog compactpob zeb drilling tshuabtsim los rau nruab nrab-rau-siab-lub zog formations. Lawv feem ntau tho qhov ntawm20-100 mm diam, nrog qhov tob feem ntau hauv qab20 m, thiab feem ntau yog siv los npaj blast qhov rau kev tswj blasting.
Los ntawm lub zog qhov chaw, pob zeb xyaum muaj xws li pneumatic, sab hauv combustion, hydraulic, thiab hluav taws xob hom. Ntawm cov no,hydraulic drilling rigCov kev teeb tsa tau nce zuj zus rau kev nkag mus ntau dua thiab kev siv hluav taws xob zoo dua, thaum lub tshuab pneumatic tseem muaj ntau tshaj plaws hauv cov haujlwm ua haujlwm.
Hauv kev xyaum, me meblasthole xyaum rigkev teeb tsa feem ntau cia siab rau kev xyaum pob zeb rau kev txhim kho tsav thiab kev rhuav tshem theem nrab.
2. Nto Blasthole Laum Rigs
Ntoblasthole xyaum rigsyog cov khoom siv tseem ceeb rau pob zeb tawg hauv qhov qhib mines. Cov variants tseem ceeb muaj xws li:

Niaj hnub nimno ntopob zeb drilling tshuabnce txais yuavhydraulic drilling rigarchitectures, integrating pressurized pub, rotary tsav, thiab npaum cuttings tshem tawm systems. Cov rigs no muab kev ua haujlwm zoo ib yam hauv kev xav tau blast-qhov program.
3. Underground Blasthole Laum Rigs
Hauv avblasthole xyaum rigslub hom phiaj qhov hauv qab 150 mm txoj kab uas hla. Rau cov av nyuaj, me-inch DTHpob zeb drilling tshuabnyiam; rau cov thee lossis softer strata, hluav taws xob lossis pneumatic rotary xyaum yog tus qauv. Laum rods nqa kauv flutes kom tshem tawm cov txiav tsis tu ncua thaum ua haujlwm.
Compacthydraulic drilling rigCov qauv tsim tau txais kev pom zoo ntawm no rau lawv cov kev tswj hwm pub noj thiab txo qhov cua nkag piv nrog cov tshuab pneumatic.
