Coal mine rods
Geological spiral laum pas nrig muaj kev ua haujlwm siab torque, uas yog siv nrog ib leeg ntsia hlau los yog ob chav helical hniav.Nws Txais yuav tshwj xeeb geological hlau thiab qib siab sib txhuam vuam txoj kev.

Coal laum yeeb nkab yog cov cuab yeej siv rau cov khoom siv mining, qhov ua haujlwm zoo sib tw zoo li lub laum yeeb nkab siv hauv cov thee seam drilling auger drilling rigs, feem ntau yog ua los ntawm cov pa roj carbon zoo, haum rau siv hauv cov thee hluav taws xob laum drilling.
Muaj ob hom coal laum yeeb nkab: khoom (dry coal laum yeeb nkab) thiab hollow (ntub coal laum yeeb nkab).Lawv muaj txoj kab uas hla ntawm Φ26, Φ28, Φ30, Φ38, Φ40, thiab lwm yam. Raws li qhov xav tau ntawm drilling thiab ntau lawm, qhov ntev yog feem ntau 0.5- 6M., Cov khoom buckle hom siv lub caij nplooj ntoos hlav pin lossis threaded txuas.Coal laum cov kav dej yog siv ua ke nrog ntau yam pneumatic anti-outburst drilling rigs, siv spiral drilling tshuab, uas muaj cov yam ntxwv ntawm ceev ceev drilling ceev, zoo drilling zoo, thiab siab drilling efficiency.Piv nrog rau cov tsoos drilling ceev, nws yog ntau dua.Qhov cuam tshuam ntawm kev tsim kho ntawm qhov kev khawb av thaum lub sij hawm coal seam excavation yog qhov tsawg, thiab nws yog dav siv hauv cov mines, gypsum mines thiab lwm yam drilling thiab mining.
Kev siv cov ntaub ntawv tshwj xeeb txhim kho lub siab xav thiab lub zog, hardness thiab hnav tsis kam ntawm lub laum pas nrig.
Lub tshuab ziab khaub ncaws hluav taws xob laum yeeb nkab yog ua los ntawm cov hlau zoo, uas tau ua tiav tshwj xeeb los txhim kho lub zog, hardness thiab hnav tsis kam ntawm lub laum yeeb nkab.Kev pabcuam lub neej ntev thiab cov txiaj ntsig kev lag luam tau txhim kho.
Hom tshiab ntawm cov dej qhuav ob lub hom phiaj tho yeeb nkab yog tsim los ntawm cov ntaub ntawv tshwj xeeb raws li cov thee laum yeeb nkab, uas txhim kho lub zog, lub zog, hardness thiab hnav tsis kam ntawm lub laum yeeb nkab, thiab txuas lub neej kev pab cuam.Nws yog 3-5 ntawm coal laum yeeb nkab.Sijhawm.Nta: lub teeb yuag, dej ntws ceev, loj-pitch hmoov paug, kev ua haujlwm siab, thiab txo qis kev siv zog ntawm cov neeg ua haujlwm.(Pitch thiab txoj kev sib txuas tuaj yeem kho raws li tus neeg siv xav tau)
