the entities in our survey captalised production stripping costs; the majority of these entities stated that they capitalised costs to the extent that actual stripping ratios exceeded average life-of-mine stripping ratios. In practice, stripping costs generally are recognised in profit or loss over the remaining life of the mine as a whole.
Coal mining is good because it is used to get a very important natural resource, coal. Coal is used in many things and without coal mining we could not do those things.
large resource of low strip ratio coal adjacent to the old underground mine. To get out and drill it and confirm the thick seams and areas of low stripping ratio resources are there, helps confirm our belief that the Chinook Vicary area can host a largeopen-cut hard coking coal mine. We look

This analysis was based on an average surface coal mine operating at the mid-point of the Australia cost curve and assumed a surface coal mine with a strip ratio of 6.5 bank cubic metres per raw tonne, producing 10 million tonnes per year of raw coal with a productivity of 13,333 raw tonnes per employee.
The initial operations will be performed at Chipanga seam with the aim to achieve higher coal recovery with a lower strip ratio. The coal handling and processing plant at the mine will have a processing capacity of 24,000t per hour. It is estimated to process approximately 17 million tonnes of coal …
North American Coal's operation the Navajo Mine supplied the Navajo Transitional Energy Company with nearly 3.7M tons of coal in 2017. The mine managed by Bisti Fuels company is located at 300 Road 4104 in Fruitland, New Mexico.
The target coal production from the mine is envisaged in 5th year of the project i.e. 3rd year of mine operation. Peak overburden load for the project has been estimated as 22 Mm3 of overburden removal during 9th to 11th years of the project life with peak stripping ratio of 5.50 cum/t. The average stripping ratio of the mine is 4.38 cum/t. The
