ʻO ka lua lanahu nui loa ma Kina - ʻO Haerwusu Open Pit Mine. Aia ka lua lanahu ma ka Inner Mongolia Autonomous Region City, Zhungeer Qi Ordos (Xuejiawan) Hikina genera ma kēia wahi, ua kūkulu ʻia ka ʻĀkau ma Heidaigou Open-pit Coal mine. Nui nā mining conveyor rollers i hoʻohana ʻia i ka maina.He 17.3 tons ka mālama ʻana i ka lanahu, ʻo ka mānoanoa o ka lanahu he 21.01 mika, ʻo ka awelika holoʻokoʻa holoʻokoʻa he 6.626 cubic mika no ke tona.ʻO 79 mau makahiki ke ola lawelawe hoʻolālā.Ua mālama ka lua lanahu mua i 6.36 tons, me ka awelika o ka wehe ʻana i ka lākiō o 4.099 cubic mika no ke tona, a me ke ola lawelawe o 32 makahiki.

ʻO ka mine lanahu no ka lehu, haʻahaʻa sulfur, haʻahaʻa phosphorus, kiʻekiʻe volatile, kiʻekiʻe calorific waiwai, kiʻekiʻe lehu heheʻe wahi o ka lōʻihi lapalapa ahi lanahu, i kapa ʻia ʻo "'ōmaʻomaʻo lanahu", lanahu me ka mana kiʻekiʻe kiʻekiʻe, he mākeke ākea ākea. ʻenehana mining o ka mining mine a me ka hahai ʻana me ka ʻōpala excavator hoʻokahi a me ke kalaka a me ka hana huki huki.I kēlā lā i kēia lā, ʻākoakoa ka hui nui o ka honua me nā kaʻa lawe kaʻa kaʻa koʻikoʻi, ua ʻike ʻia ʻo ia ka "hao a me ke kila hui Mining toil" monster mai ka holo wikiwiki ʻana ma Wujin mining environment, hana waiwai nui.

Aia ka mine lanahu ākea ma ka Ordos Plateau, ʻo ia kekahi o nā wahi koʻikoʻi o ka wai a me ka lepo lepo ma Kina.ʻO ka awāwa o ka ʻili mua he kū a me ka pae, ʻaʻohe mea kanu, he koʻikoʻi ka hili ʻana o ka makani a me ka wao akua, a he ʻino loa ke ʻano kūlohelohe.Mai ka hana maʻamau, e hui pū ʻia ka lua hāmama me ka hoʻomohala ʻana a me ka ʻōmaʻomaʻo.

ʻO ka lua lanahu nui loa o ka honua - ʻo Rochester coal mine.Aia ka lua lanahu ma ka Powder River Basin o Wyoming, ʻo ia ka ʻeli lanahu nui loa o ka honua me nā tona he 23.ʻO ka mina kekahi o ka ʻāina lanahu nui loa o ka honua, e ka hui ikehu ʻo Peabody. I kēlā me kēia makahiki e kūʻai aku ai ka maina i nā mea hoʻokele mining conveyor.Aia ka moena lanahu o Rochester mine mine he 18.3 mika o ka papa honua he 76.2 mika a holo aku no 80.47 mau kilomita.He 258.9 kilomika kuea ka nui o ka maina, e like me ka nui o Wakinekona, D.He 25 a 30 mau makahiki e hoʻopau ai i ka hana ʻana.ʻO ka hana lanahu ʻo Rochester i ʻike ʻia ʻo ka lanahu maʻemaʻe loa, ka awelika wela o ka lanahu no ka paona o 8800 British thermal units, a me ka sulfur ma lalo o 0.2%.

Ua hoʻohana ka lanahu i ka dragline overcast stripping a me ka bakeke hoʻokahi a me ka ʻenehana kaʻa, hilinaʻi i nā mea hana mechanized nui, hoʻomaikaʻi nui i ka hana pono.I kēlā me kēia lā, e holo ana ma kahi o 21 mau huakaʻi o nā kaʻaahi i hoʻopiha ʻia me ka lanahu mai Wyoming's Rochester mine a hiki i 100 mau mea hoʻoheheʻe i ka lanahu a puni ka ʻāina.ʻO nā kaʻa lanahu i hoʻopaʻa ʻia ma ka hale koʻu lanahu ʻo Rochester e hiki ke hoʻouka i ka nui ma mua o 440 tons. Ua ʻike ʻia ke kūlanakauhale ʻo ka "world image center", "flower city", kēlā me kēia punawai, pua nā pua, a no laila "pua. kūlanakauhale" ma ka honua.
