Väljund
About 3.8 m³/s / 229 m³/min / 8,100 cfm. Governing kriteerium: diisel seade.
Kaevanduskalkulaator
Works offline in the brauser
Supports m³/s, m³/min, and cfm
Handles kW and hp inputs
Kiire maa-aluse ventilatsiooni õhuvoolu kalkulaator
Quickly estimate nõutav õhuvool from tööline count, diisel seade count, võimsus, and seisund factors.
This is a preliminary estimate for early planning, training, and võrdlus. It is not a substitute for lõpp ventilatsioon design or regulatory compliance.
Safety märkus
All calculations stay in this brauser and are not sent to any server.
- For preliminary estimates, training, and võrdlus only. Not a substitute for lõpp ventilatsioon design or legal compliance.
- Review gas, dust, heat laadimine, oxygen deficiency, and post-blast dilution separately.
- Adjust diisel seisund factors to match site standards and seade maker guidance.
Kuidas kasutada
Märkused
- Enter the tööline count for the area you want to ventilate.
- Lisa one row per diisel seade type and enter count, võimsus, seisund tegur, and samaaegsus.
- Ava seaded if you need to change õhuvool coefficients, miinimum õhuvool, or kümnendarv places.
- Check the governing kriteerium and the lõpp recommended õhuvool in the tulemus pane.
Examples
Sisend / Väljund
Case 2: 4 töölised / 1 service veok / 30 kW / kohalik miinimum 120 m³/min
Sisend
Workers=4, equipment=service truck ×1, power=30 kW, condition=controlled, simultaneity=100%, local minimum=120 m³/min, reserve=10%
Väljund
About 2.2 m³/s / 132 m³/min / 4,700 cfm. Governing kriteerium: kohalik miinimum õhuvool.
Sõnastik
Maa-alune ventilatsioon õhuvool calculation
- Nõutav õhuvool
- The estimated amount of air that should be supplied to the maa-alune working area.
- Governing kriteerium
- The largest requirement among personnel, diisel seade, and kohalik miinimum õhuvool.
- Samaaegsus
- The jaga of seade that is expected to operate at the same aeg.
- Seisund tegur
- A viide tegur that reflects differences in seade seisund or aftertreatment.
- Reserv margin
- An added percentage above the governing kriteerium to keep the estimate conservative.
Formulas
Internal calculations use m³/s as the base unit.
- Q_people = N_people × R_people
- Q_row = N_i × P_i × F_condition_i × F_simultaneity_i × R_diesel
- Q_governing = max(Q_people, ΣQ_row, Q_local_min)
- Q_design = Q_governing × (1 + reserve / 100)
- 1 m³/s = 60 m³/min = 2118.88 cfm
Frequently asked questions
Märkused
Can I use this for lõpp ventilatsioon design?
No. This is for preliminary estimates, training, and võrdlus. Lõpp design must follow regulations, site standards, and professional judgment.
Does it support both m³/s and cfm?
Yes. The kuva can switch, and the internal calculation uses SI units.
What does the seisund tegur mean?
It is a viide tegur for site standards, aftertreatment, maintenance state, and similar differences.
What if there are multiple diisel seade types?
Lisa rows and enter the count, võimsus, and factors for each seade type separately.
Can I use it offline?
Yes. It runs entirely in the brauser and does not use external APIs.
Märkused
Internal calculations use m³/s as the base unit.
- This tool provides viide calculations. Lõpp design must prioritize kohalik regulations, internal standards, and manufacturer conditions.
- Adjust the seisund and tööline coefficients to your site assumptions.
- Enter only the seade that actually runs at the same aeg if you want easier comparisons.
