Mining slurry twj tso kua mis yog cov cuab yeej siv tseem ceeb siv hauv kev ua haujlwm mining los thauj cov slurry uas muaj cov khoom siv, xws li ore pulp, tailings, coal slime, thiab lwm yam.
Lub hom phiaj tseem ceeb
Ore slurry conveying: Siv los thauj cov txiaj ntsig ore slurry (lub slurry uas muaj cov khoom siv) los ntawm ib qho chaw mus rau lwm qhov, xws li los ntawm lub zeb mus rau lub tshuab flotation, los yog los ntawm lub pas dej tailings mus rau lub siab pom.
Tailings conveying: Cov tailings tom qab ua cov ntxhia yog thauj mus rau lub pas dej tailings los ntawm cov kav dej. Qee qhov siab - siab slurry diaphragm twj tuaj yeem ua tiav ntev - nrug thiab siab - siab conveying (nrog rau kev tsim siab txog li 16MPa).
Drilling flushing: Thaum lub sij hawm geological drilling los yog thee mine qhov drilling, av nkos los yog dej ntshiab yog pumped rau hauv lub borehole kom txias lub laum me ntsis, tshem tawm pob zeb khib nyiab, thiab stabilize lub borehole phab ntsa.
Coal seam fire extinguishment thiab qhov sealing grouting: siv hauv cov mines thee los txhaj slurry rau thee seam tua hluav taws lossis sealing ntawm boreholes.
Dredging thiab desilting: siv rau kev tshem tawm cov av hauv thaj chaw xws li mine pas dej, sedimentation basins, thiab tailings pas dej.
Kev faib tawm ntawm cov xwm txheej siv tau
Cov txheej txheem kev siv nyiaj hauv kuv: thauj cov khoom nyoos slurry, mloog zoo slurry, thiab tailings slurry, nrog concentrations txog li 50% mus rau 60% (los ntawm qhov hnyav).
Kev tshawb nrhiav geological: Nruab nrog lub qhov laum thiab cov tub ntxhais xyaum, muab cov kua dej ntws tawm.
Kev tiv thaiv ib puag ncig thiab kev kho cov khoom pov tseg: Kho cov slag slurry uas muaj cov hlau hnyav lossis cov khoom tsis zoo kom muaj kev nyab xeeb kev thauj mus los.
Tshwj xeeb engineering: xws li lubrication grouting thiab av reinforcement grouting nyob rau hauv cov yeeb nkab jacking siv.
