Syllabus
Mine Fires: Accidental Fires – it causes and precautions, Survey of various causes of mine fires with statistical data of Indian mines. Physical and chemical factors governing proneness to fire in coal and metalliferous mines
Various methods adopted to combat fires and their advantages and disadvantages. Advances in firefighting techniques and equipment’s, rescue operations in fire-zones.
Spontaneous Heating: Various causes of spontaneous heating and statistical data in Indian mines, Theories of spontaneous heating of coal, Geological, Mining and Seam factors governing spontaneous heating. Intrinsic and extrinsic properties of various substances e.g. -porosity, permeability, pore distribution, moisture etc. on spontaneous heating Different experimental techniques including modern techniques like DTA/TGA and DSC to measure liability indices and relative proneness of spontaneous heating use of clean coal technology and neural network to detect spontaneous tendency, effect of microwave treatment and pyrite removal on spontaneous heating Sampling of mine atmosphere, Interpretation of mine air analyzing data, fire risk management, environmental indices, Different methods to seal off fire areas Reopening of sealed off fire areas Early detection of spontaneous heating in mines and stacks, recent trends to eliminate recurrence of spontaneous heating.
Course Objectives
- To know the reasons, mechanism and theories behind fire
- To know how to protect the mine from fire problem
- To make the case studies so that recurrence should not occur
