LImestone and coal are different because of their outcomes. Limestone , after the cementing, becomes a rock. Coal, after the pressing together, becomes a fossil.
Coal mining: Areas where limestone is found often have coal deposits Steel making: Limestone is used as catalyst in the smelting process from ore to liquid iron. Railways: ballast on which the track rests is usually limestone. It was used as a building material mainly for road bridges and station buildings
