Yuav siv cov roj ntes li cas hauv cov mines
Mining xwm txheej tshwm sim txhua xyoo, thiab kev phom sij ntawm kev ua haujlwm hauv av tau pom tseeb rau txhua tus. Txawm li cas los xij, rau kev txhim kho cov peev txheej, kev ua haujlwm hauv av tsis tuaj yeem zam tau, yog li peb yuav tsum tau npaj rau kev nyab xeeb, thiab cov khoom siv roj av yog ib qho ntawm lawv. Ib qho, peb yuav tsum siv lub tshuab ntsuas roj los txheeb xyuas qhov kev faib tawm ntawm huab cua hauv av ua ntej peb tuaj yeem pib ua haujlwm li qub. Gas detectors yog qhov tseem ceeb hauv kev siv downhole!
Gas detectors yog cov sensors uas ntes roj muaj pes tsawg leeg thiab concentration. Rau qee txoj haujlwm (mines) nrog rau kev nyab xeeb kev nyab xeeb, lawv tuaj yeem txo qhov tshwm sim ntawm qee qhov kev sib tsoo mining.
Hais txog kev txhim kho thiab siv cov khoom siv roj av, cov ntaub ntawv tshawb fawb luam tawm los ntawm US National Institute of Occupational Health thiab Safety thiab US National Occupational and Health Administration tau qhia tias ntau qhov kev sib tsoo ntawm qhov chaw tuag muaj feem cuam tshuam nrog cov pa roj ntawm qhov chaw. Cov khoom phom sij no tuaj yeem tshwm sim ua ntej cov neeg ua haujlwm nkag mus rau qhov chaw kaw, lossis tuaj yeem tsim los ntawm lawv cov haujlwm hauv nws. Feem ntau ntawm cov xwm txheej tshwm sim vim tsis pom cov pa phem ua ntej cov neeg ua haujlwm nkag mus thiab thaum ua haujlwm hauv qhov chaw kaw. Tag nrho cov kev tshawb fawb no qhia tau hais tias qhov tseem ceeb ntawm cov khoom siv hluav taws xob muaj phom sij nyob rau ntau theem uas cuam tshuam nrog kev nkag mus hauv qhov chaw.
Cov roj muaj pes tsawg leeg hauv mines sawv cev rau ntau yam xwm txheej txaus ntshai. Cov pa roj carbon monoxide muaj xws li: carbon monoxide, carbon dioxide, nitrogen oxides, sulfur dioxide, thiab lwm yam, nrog rau cov pa oxygen tsis txaus. Qee qhov xwm txheej, methane tuaj yeem ncav cuag qhov hnyav hnyav. Txij li thaum methane tsis muaj lub tswb nrov, methane tuaj yeem sib sau ua ke rau qhov tawg ua ntej cov neeg ua haujlwm paub tias muaj kev phom sij tshwm sim. Qhov tshwm sim ntawm txhua qhov hluav taws kub, xws li tus neeg ua haujlwm lub teeb miner, yuav ua rau tawg.
