Yuav siv lub mine lub gas detector li cas
Yuav muaj kev sib tsoo mining txhua txhua xyoo, thiab qhov txaus ntshai ntawm kev ua haujlwm hauv av yog 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. Yog li ntawd, peb yuav tsum tau npaj rau kev teeb tsa, thiab lub ntsuas hluav taws xob yog ib qho ntawm lawv. Ib qho, peb yuav tsum siv lub tshuab ntsuas roj los soj ntsuam qhov kev faib tawm ntawm huab cua hauv qhov dej ua ntej peb tuaj yeem pib ua haujlwm ib txwm. Gas detectors yog qhov tseem ceeb hauv kev siv downhole!
Gas Detector yog ib qho sensor uas kuaj pom cov roj muaj pes tsawg leeg thiab concentration. Rau qee txoj haujlwm (mines) nrog rau kev nyab xeeb kev nyab xeeb, nws tuaj yeem txo qhov tshwm sim ntawm qee qhov kev puas tsuaj rau kuv.
Hais txog kev txhim kho thiab kev siv cov cuab yeej siv roj, cov ntaub ntawv tshawb fawb luam tawm los ntawm National Institute of Occupational and Health Research thiab National Occupational and Health Bureau of the United States tau qhia tias muaj ntau yam xwm txheej tuag nyob rau hauv qhov chaw kaw muaj feem cuam tshuam nrog cov khoom siv roj hauv qhov chaw. . Cov khoom siv phom sij no tuaj yeem muaj ua ntej cov neeg ua haujlwm nkag mus rau hauv qhov chaw kaw, lossis tuaj yeem tsim los ntawm lawv cov haujlwm nyob rau hauv. Feem ntau ntawm cov xwm txheej tshwm sim vim tsis muaj kev kuaj pom cov pa phem ua ntej cov neeg ua haujlwm nkag mus thiab ua haujlwm hauv qhov chaw kaw. Tag nrho cov kev tshawb fawb no taw qhia txog qhov tseem ceeb ntawm cov khoom siv roj phom sij ntawm txhua theem koom nrog hauv qhov chaw nkag.
Cov pa roj carbon monoxide muaj nyob hauv cov mines sawv cev rau ntau yam kev phom sij, uas muaj cov pa roj carbon monoxide, carbon dioxide, nitrogen oxides, sulfur dioxide, thiab lwm yam, nrog rau oxygen tsis txaus. Qee qhov xwm txheej, methane kuj tseem tuaj yeem ncav cuag cov khoom tawg. Txij li thaum methane tsis muaj cov khoom ceeb toom, nws tuaj yeem tsim kom muaj qhov tawg sai sai thaum cov neeg ua haujlwm paub tias muaj kev phom sij. Qhov tshwm sim ntawm txhua qhov hluav taws kub, xws li tus neeg ua haujlwm lub teeb miner, yuav ua rau muaj kev sib tsoo tawg.
