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.

What's the difference between engineering and engineering technology, and how can you tell the two apart?
Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings, and railways. is traditionally broken into a number of sub-disciplines?? It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering can take place in the public sector from municipal public works departments through to federal government agencies, and in the private sector from locally based firms to global Fortune 500 companies. ??? It takes 60 kW to keep the interior of a certain house at 60°C when the outside temperature is 10°C. This heat flow is usually obtained directly by burning gas or oil. Evaluate the power required if the 60 kW heat flow were supplied…
