Suggested Micro Project

Micro project

• Prepare a report on measurement of different gases by using multigas detector by visiting nearby underground mine.
• Prepare a report on mine fan house regarding water gauge by visiting nearby underground mine.
• Prepare report on design parameters of evasee.
• Present a power point presentation on various types of fans used in Indian underground mines for ventilation purpose.
• Prepare any one model of ventilation devices.
• Conduct a ventilation survey in nearby underground mine and prepare a report of it.
• Prepare a report/paper on history of gas testing by old conventional methods.

Laboratory Equipment

1. Multigas detector(drager X-am 5600/ Mini warn:- It has an ergonomic design, and used for detection of exposive, combustible and toxic gases as well as oxygen. 1
2. Model of Centrifugal fan 10
3. Model of Axial flow fan. 11
4. Model of Air crossing. 12
5. Model of Ventilation stopping. 13
6. Model of Regulator. 14
7. Model of Airlock. 16
8. Vane Anemometer :- It is an instrument to determine the distance travelled by air in a given time and is used where the air velocities are between 60m/min and 1000m/min. Its possible measuring wind speed is 1-15m/sec. 17
9. Velometer :- It is an electronic device which directly measure the air velocity in m/sec at any point of observation. Its range varies from 0-15m/sec. 18,19
10. MSA Methanometer :- MSA D6 Methanometer is commonly used in our coal mines, It is suitable for spot checking of gas accumulation with measurement range from 0 to 5 % by volume, The battery lasts for nearly 1000 ten-sec and the complete charging takes about 14 hours. 2
11. Inclined Manometer :- Its is used for measuring pressure/ water gauge in mines. Maximum range of pressure measurement is 250mm Wg. 20,21
12. Pitot Static tube :- Its is used to measure to measure the static pressure, velocity pressure or the total pressure. L-type pitot tube feature a modified ellipsoidal head with a single forward facing hole (for total pressure) and a ring of side holes (for static pressure). 22,23
13. Flame safety lamp ( GL5, GL50, GL60, GL7 ) :- It is used for detection of inflammable gases (Firedamp) in underground coal mines, It can detect accumulation and perecntage of firedamp in the atmosphere. It is manufactured by J.K. Dey & Sons, Kolkata. 3,4,5,6
14. Whirling hygrometer :- It is used to determine relative humidity in mine air. Its range generally varies from -5 to 50 degree celcius. 7,8
15. Kata thermometer :- It is used to measure the cooling power of mine air, It consist of an alcohol thermometer with a large bulb 4cm. long and 2cm. in diameter and a stern 20cm. long. It is graduated at two points namely 38 degree celsius and 35 degree celsius 9
