Keeb Kwm Ntawm Kev Txhim Kho Ntawm Mining Machinery

Mining machinery suav nrog cov cuab yeej siv tshuab siv ncaj qha rau kev rho tawm cov khoom muaj txiaj ntsig zoo thiab rau kev npaj ua haujlwm mining. Nws feem ntau suav nrog excavation machinery rau extracting metallic thiab non-metallic ores; thee mining machinery rau extracting thee; thiab petroleum drilling thiab extraction machinery rau extracting roj, thiab lwm yam.
Thawj pneumatic disc -hom thee cutter yog tsim los ntawm British engineer Walker thiab tau ua tiav nyob rau xyoo 1868. Nyob rau xyoo 1880, ntau pua lub qhov dej hauv Teb Chaws Asmeskas tau ua tiav kev xyaum siv chav ua haujlwm -powered percussion xyaum. Nyob rau hauv 1907, rotary cone xyaum yog qhia rau drilling roj thiab natural gas qhov dej; Tom qab ntawd, pib xyoo 1937, cov kev xyaum no kuj tau siv rau kev ua haujlwm drilling hauv qhib- qhov chaw thee mines.
Excavation machinery yog hais txog cov cuab yeej siv tshuab feem ntau siv nyob rau hauv ob qho tib si hauv av thiab qhib - qhov chaw mining. Nws encompasses drilling machinery rau tho blast qhov; excavating thiab loading machinery rau khawb thiab tuav ore thiab pob zeb; thiab tunneling machinery rau kev tsav tsheb nce, ntsug shafts, thiab kab rov tav txoj kev.
Drilling machinery yog dav categorized rau hauv pob zeb xyaum thiab tshawb nrhiav kev xyaum; qhov tom kawg yog ntxiv subdivided rau hauv qhib -qhov drilling rigs thiab underground drilling rigs. Pob zeb laum yog cov tshuab tsim los txhawm rau txhawm rau txhawm rau qhov tawg- feem ntau yog li ntawm 20 mus rau 100 mm inch thiab mus txog 20 meters hauv qhov tob-hauv nruab nrab- nyuaj rau cov pob zeb nyuaj. Raws li lawv cov khoom siv hluav taws xob, lawv tau muab faib ua pneumatic, sab hauv combustion, hydraulic, thiab hluav taws xob pob zeb xyaum, nrog pneumatic pob zeb xyaum yog hom siv dav tshaj plaws. Qhib- qhov drilling rigs raug cais raws li cov txheej txheem tshwj xeeb uas siv los rhuav tshem lub pob zeb, suav nrog cable percussion drills, rotary drills, rotary cone laum, thiab rotary -percussive xyaum; ntawm cov no, cable percussion xyaum tau maj mam hloov los ntawm lwm hom vim lawv cov kev ua haujlwm qis dua.
Tunneling machinery muaj cov cuab yeej siv tshuab tsim los ncaj qha tawg ore thiab pob zeb-yog li tsim txoj hauv kev lossis shafts-los ntawm kev siv lub zog axial thiab kev sib hloov ntawm cov cuab yeej txiav los ua kom muaj kev sib tsoo lossis dov tawm tsam lub ntsej muag pob zeb. Cov cuab yeej txiav ua haujlwm suav nrog cov tshuab txiav disc, npoo- cov hniav cutters, khawm cutters, thiab milling cutters. Nyob ntawm seb hom kev taug kev tshwj xeeb raug khawb, cov tshuab no tau muab faib ua cov borers, ncej borers, thiab kab rov tav tunneling tshuab.
