Manyan ayyukan allurar nitrogen a ma'adinan kwal sune kamar haka.

Hana Konewar Kwal Ba Tare Da Kai Ba

A lokacin aikin haƙar kwal, jigilar kaya da taruwa, yana da saurin haɗuwa da iskar oxygen a cikin iska, yana fuskantar jinkirin amsawar iskar oxygen, tare da ƙaruwar zafin jiki a hankali, kuma daga ƙarshe yana iya haifar da gobarar ƙonewa kwatsam. Bayan allurar nitrogen, yawan iskar oxygen na iya raguwa sosai, wanda ke sa amsawar iskar oxygen ta yi wahalar ci gaba, ta haka yana rage haɗarin ƙonewa kwatsam da tsawaita lokacin fallasa ga kwal. Saboda haka, masu samar da sinadarin nitrogen na PSA sun dace musamman ga yankunan goaf, tsoffin yankunan goaf, da yankuna masu iyaka.

Rage Haɗarin Fashewar Iskar Gas 

Iskar methane galibi tana nan a ma'adinan kwal na ƙarƙashin ƙasa. Idan yawan methane a cikin iska ya kasance tsakanin kashi 5% zuwa 16% kuma akwai tushen wuta ko wurin zafi mai yawa, fashewar na iya faruwa. Allurar nitrogen na iya zama da amfani ga dalilai biyu: rage yawan iskar oxygen da methane a cikin iska, rage haɗarin fashewa, da kuma yin aiki a matsayin hanyar kashe gobara ta iskar gas mara aiki idan gobara ta tashi don hana yaɗuwar wutar.

Kula da Yanayi Mara Inganci a Yankin da Aka Tsare

Wasu wurare a cikin ma'adinan kwal suna buƙatar a rufe su (kamar tsoffin lunguna da wuraren da aka haƙa), amma har yanzu akwai haɗarin ɓoye na kashe gobara ko tarin iskar gas a cikin waɗannan yankuna. Ta hanyar ci gaba da allurar nitrogen, za a iya kiyaye yanayin rashin iskar oxygen da babu tushen wuta a wannan yanki, kuma za a iya guje wa bala'o'i na biyu kamar sake kunna wuta ko fashewar iskar gas.

Ajiye Kuɗi & Aiki Mai Sauƙi

Idan aka kwatanta da sauran hanyoyin kashe gobara (kamar allurar ruwa da cikawa), allurar nitrogen tana da fa'idodi masu zuwa:

1. Ba ya lalata tsarin kwal.
2. Ba ya ƙara danshi a ma'adinan.
3. Ana iya sarrafa shi daga nesa, ci gaba da sarrafawa

A ƙarshe, allurar nitrogen a cikin ma'adinan kwal hanya ce mai aminci, mai kyau ga muhalli kuma mai inganci don hana yawan iskar oxygen, hana ƙonewa kwatsam da kuma dakatar da fashewar iskar gas, ta haka ne ake tabbatar da tsaron rayukan ma'aikatan hakar ma'adinai da kadarorin ma'adinai.
