Mine Environmental Engineering Lab

List of Experiments / Activities

1. Water Quality Analysis:
2. 1Determination of Hardness (Total, Calcium, and Magnesium Hardness): Measuring the concentration of dissolved mineral ions (primarily calcium and magnesium) that cause water hardness, usually by EDTA titration.
3. 2Determination of Dissolved Oxygen (DO): Measuring the amount of oxygen available in water, crucial for aquatic life and indicating organic pollution (e.g., using Winkler method or DO meter).
4. 3Determination of Biochemical Oxygen Demand (BOD): Measuring the amount of oxygen consumed by microorganisms while decomposing organic matter in water, indicating organic pollution load.
5. 4Determination of Chemical Oxygen Demand (COD): Measuring the amount of oxygen required to chemically oxidize organic and inorganic matter in water, providing a faster estimate of pollution than BOD.
6. 5Determination of Heavy Metals (e.g., Iron, Copper, etc.): Using methods like spectrophotometry or atomic absorption spectroscopy to quantify specific heavy metal contaminants.
7. Air Quality and Mine Environment Monitoring:
8. 6Detection of Mine Gases (Methane, Carbon Monoxide, Carbon Dioxide, Hydrogen
9. Sulfide, Oxygen deficiency): o Using multi-gas detectors. o Using Flame Safety Lamp for methane detection (accumulation and percentage tests). o Demonstration of CO-detectors and Methanometers. o Analysis of gas samples using an Orsat apparatus (for CO2, O2, CO).
10. 7Measurement of Relative Humidity using a Whirling Hygrometer (Sling Psychrometer): Understanding psychrometric principles and calculating humidity.
11. 8Measurement of Air Velocity and Quantity (Anemometer and Velometer): Using various instruments to measure airflow in mine roadways and calculate air quantity.
12. 9Measurement of SPM (Suspended Particulate Matter) and PM10 (Particulate Matter <10 micrometers) with High Volume Sampler: Assessing airborne dust levels. Environmental Management and Impact Assessment (Demonstrations/Case Studies):
13. 10Field Visit to Water/Sewage Treatment Plant or Mine Site: Observing real-world environmental control measures.
14. 11Study of Mine Air-Conditioning Plants: Understanding methods for controlling temperature and humidity in deep mines.
15. 12Layout of Lamp Rooms: Understanding safety equipment and their maintenance.
