Kev sib tham luv luv ntawm txoj kev quarrying pob zeb

Kev rho tawm, kev ua, kev lag luam, thiab siv cov pob zeb ntuj yog ib qho kev ua rau tib neeg thaum ub uas tau nthuav dav tag nrho cov keeb kwm ntawm tib neeg kev vam meej. Txij li thaum xyoo 1990, nrog rau kev loj hlob ntawm kev lag luam tshiab xws li Tuam Tshoj, lub tsev thiab kev lag luam pob zeb zoo nkauj tau tsim sai heev.

Raws li lub Koom Haum Ntiaj Teb Lub Tsev thiab Kho Hniav Pob Zeb, los ntawm 2025, lub ntiaj teb kev noj txhua xyoo ntawm cov pob zeb ntuj yuav ncav cuag 4 billion square meters, nrog marble accounting rau 40%, granite rau 50%, thiab cov seem muaj xws li sandstone, slate, basalt, limestone, agate, thiab lwm yam. Peb caug xyoo dhau los ntawm Tuam Tshoj txoj kev lag luam kev lag luam tau loj hlob sai, kev loj hlob thiab kev loj hlob. Tuam Tshoj yog ib lub ntiaj teb tseem ceeb tshaj cov neeg tsim khoom thiab cov neeg siv khoom ntawm pob zeb.

 

Qhov kev thov muaj zog no tau txhawb txoj kev loj hlob ntawm lub ntiaj teb pob zeb kev lag luam. Cov pob zeb tsoos - cov teb chaws tsim khoom xws li Ltalis thiab Spain tau pom lawv cov khoom lag luam poob xyoo los ntawm xyoo vim muaj peev txheej thiab kev cuam tshuam ib puag ncig; thaum lub teb chaws xws li Qaib Cov Txwv, Brazil, Iran, Is Nrias teb, thiab tim lyiv teb chaws tau ntsib kev loj hlob sai nyob rau hauv ntuj pob zeb extraction.

 

Lub ntiaj teb lub pob zeb tsim thiab ua chaw yog hloov ntawm Tebchaws Europe mus rau Tuam Tshoj hauv Asia. Niaj hnub nimno pob zeb mining thiab ua nyob rau hauv Tuam Tshoj yog piv txwv los ntawm kev siv Italian hlau saws nyob rau hauv lub Hubei Dahualü pob zeb mine, qhia ib tug txheej txheem ntawm kev taw qhia, kev kawm, imitation, innovation, thiab refinement kom ua tiav txoj hauj lwm.
