MINING ENVIRONMENT – I (MI302)

III-Semester

Introduction

Ventilation requirements in mines, natural ventilation and mechanical ventilation.

Mine Gases

Composition of atmospheric air. Mine gases - occurrences, properties, physiological effects, detection; sampling, analysis, monitoring. Methane layering, methane drainage. Radon and its daughter products - effects and control.

Heat and Humidity

Sources, effects and control of heat and humidity in mines. Cooling power of mine air – psychrometry, Kata thermometer, effective temperature. Air conditioning. Spot coolers.

Airflow in Mine Workings

Reynold’s number, laminar and turbulent flow. Square law of mine ventilation. Frictional and shock losses. Equivalent orifice. Resistance in series and parallel. Ventilation control devices. Splitting of air current. Ventilation network analysis – conventional method and scope for computer application.

Airborne Respirable Dust

Definition – generation, physiological effects, sampling, measurement and control measures.

Mine Illumination

Flame safety lamp – construction, maintenance, gas testing. Cap lamps. Lamp room layout and organization. Underground lighting from mains. Illumination standards. Photometry. Illumination survey.
