Abstract: Hōʻike ka pepa i ka EPIROC's COP MD20 hydraulic rock drill a nānā i kāna mau pono i ka hoʻohana ʻana.Hoʻohālikelike ʻia kēia drill pōhaku hydraulic me COP 1838 ma ke ʻano o nā hiʻohiʻona.Nānā pū ka pepa i ke ala ʻenehana o ka ʻōnaehana hoʻihoʻi ʻaila ʻelua ʻaoʻao a me ka manaʻo o ka huahana COP 1838.

Nānā o MD20 hydraulic rock driller
Wahi a cm.hc360.com, ma ka Las Vegas 2016 Mining Show, USA (September 26-28), ua hōʻike ʻo Atlas Copco i kāna Boomer S2 underground rock drilling drill Jumbo i ʻoi aku ka lōʻihi a me ka naʻauao a me ka COP MD20 pōhaku driller.ʻOi aku ka kiʻekiʻe o ka wikiwiki o ka drill Jumbo ma mua o nā huahana like ma ka mākeke e 10%.I ka manawa like, ua hoʻomaikaʻi ka ʻenehana damping vibration o ka pōhaku driller i ke kumukūʻai kūpono a me ke ola lawelawe o ke koʻokoʻo wili.Ua hoʻokumu ʻia ʻo COP MD20 i ka makahiki 2015.
No ka maʻalahi, e kapa ʻia ʻo COP MD20 e like me
MD20 ma keia hope aku.Kū ʻo MD no Mining Drift, ʻo ia hoʻi

Hoʻohana nui ʻia ka mea hoʻoheheʻe pōhaku no koʻu ala ala ala me 20 no ka mana hopena hopena o 20kW.ʻO 33 - 64mm ka anawaena o ka lua wili ʻana o MD20, a ʻo ke anawaena puka maikaʻi loa he 45mm, ʻo ia ke anawaena puka maʻamau no ka tunneling alanui pālahalaha.
ʻO ka Mining & Rock Excavation Division o Atlas Copco i lilo i Epiroc ma Iune 18, 2017, ka mea i hoʻoili i nā huahana a me nā ʻoihana e pili ana i nā mea hoʻoheheʻe pōhaku o Atlas Copco.Ma nā hōʻikeʻike mīkini ʻenekinia like ʻole, ua hōʻike ʻia ka MD20 rock driller ma ke ʻano he hōʻike nui, a ʻo kona hiʻohiʻona nani i huki nui ʻia.E nānā i ka Fig. 1 no ke ʻano o ka MD20 rock driller.
ʻO ka Boomer S2 underground rock drilling drill Jumbo i hana ʻia ma Suedena me MD20 rock driller ua hoʻohana ʻia e nā mea kūʻai aku e like me Shandong Gold ma Kina no nā mea hou aku.
