Ex-Proof Smartphone Distributor in Kalimantan Mining
Kalimantan hosts some of Indonesia's largest open-pit coal mines, including Kaltim Prima Coal at Sangatta in East Kalimantan and Adaro's Tutupan mine in South Kalimantan. Hazardous-area work centres on fuel storage, coal handling and preparation, and mine power plants. An Ex-proof smartphone distributor in Kalimantan coal mining region would carry the IS-04Z1 to these buyers once certification completes.

Field notes · Kalimantan coal mining region
More about Kalimantan coal mining region that matters for portable equipment
Kalimantan coal mining region: infrastructure
State utility PLN plans additional coal-fired capacity and has begun co-firing biomass at 17 power plants, so mines and power stations are linked by long coal supply chains.
Kalimantan coal mining region: people and language
The coal industry is fragmented, with a few large producers and many small firms, so equipment rules and safety culture can vary widely between neighbouring mine sites.
Kalimantan coal mining region: climate and equipment wear
Coal dust is a recognised health and handling issue in Indonesian mining, so dust control, cleaning and sealed enclosures matter for electronics used around crushers, conveyors and stockpiles.
Kalimantan coal mining region: rules and approvals
A Domestic Market Obligation requires coal miners to allocate 25 percent of production to local use at a fixed price, which shapes how much coal is railed and barged to domestic power stations.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Kalimantan coal mining region. A marking check would first separate gas from dust. Coal preparation plants are Zone 21 dust areas in the sheet; fuel stores are gas. The IS-04Z1 target marking, II 2 G Ex ib IIC T4, addresses gas only, so dust areas need separate assessment.

Questions · Kalimantan Mining
Frequently asked questions
Can we buy an Ex-proof smartphone in Kalimantan Mining today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an Ex-proof smartphone in Kalimantan Mining cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Kalimantan coal mining region would use it?
Likely candidates are coal handling and preparation plants (dust, zone 21), fuel and lubricant storage, mine-site power generation, coal loading terminals. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Kalimantan coal mining region?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Kalimantan coal mining region.
Does heavy rain in Kalimantan affect devices used at mine sites?
Kalimantan has a tropical climate with frequent heavy rain, so devices in open-pit and barge-loading areas face water, mud and dust together. Users typically want good ingress protection and cleaning routines; check the specification against the mine's rules.
Is there a legal requirement to supply coal domestically that affects mine logistics?
Indonesia has a Domestic Market Obligation requiring miners to allocate a share of production, 25 percent in the cited rule, to the domestic market. It affects shipping and customer mix rather than device choice, but it explains continuous coal handling at ports and power plants.
Are coal mines in Kalimantan treated as gas or dust hazards?
Open-pit coal sites mainly raise dust hazards at handling and preparation plants, plus gas hazards at fuel storage. The sheet does not assume methane. The operator's classification decides. Confirm with the site operator's HSE team which areas apply.
