Mining yam ntxwv ntawm hard pob zeb mines
Txoj kev mining ib txwm siv rau kev khawb pob zeb yog nplaim taws txiav tshuab excavation, qhov drilling ua ke nrog phau ntawv sib cais los yog tswj blasting splitting mining. Tam sim no, nplaim taws txiav tshuab mining txoj kev tsis tshua siv, thiab muaj ob txoj kev uas tau siv dav:
High-step mining method
High-step mining txoj kev siv lub tshuab xaim pom thiab lub qhov drilling ua ke nrog cov khoom sib cais lossis tswj blasting splitting; Cov cuab yeej siv pob zeb nyuaj thiab cov txheej txheem tsim nyog rau ntau lub cev ore. Cov hlau pom tshuab ua ke nrog txoj kev drilling thiab sib cais tuaj yeem siv rau kev ua haujlwm siab ntawm ntau hom tawv pob zeb ore lub cev. Nws yog qhov tsim nyog rau kev siv cov pob zeb nyuaj mines nrog cov khoom tsis zoo sib cais thiab tsim cov kab nrib pleb.
low-step mining method
Tag nrho sawing los yog sawing splitting low-step mining method combines a wire saw machine with a bead saw or manual splitting method. Lub disc pom yog tsim rau cov mining nrog cov xim sib xws thiab tsis muaj kab nrib pleb - qis-qib mining ntawm cov pob zeb nyuaj nrog cov kev taw qhia zoo, cov kab nrib pleb tsis zoo, thiab kev ncaj ncees zoo.
