A nearly horizontal coal seam having 10 degrees dip is lying below the 75 m overburden. Find out the overall stripping ratio based on the following information: a. Seam thickness: 20 m b. Strike length of the coal seam: 1.5 km C. Horizontal extend of the coal seam: 2.0 km d. Overall pit slope angle: 40 degrees Density of the coal and overburden are 2200 kg/m³ and 2300 kg/m³ respectively. e. f. Coal recovery: 80% Assume all other relevant information as per your judgment.
