Coal India Ltd (CIL) has envisaged processing the fragmented rock (known as Overburden Rocks (OB) for sand production in mines.
OB material contains about 60% sandstone by volume which is harnessed through crushing and processing of Overburden.
M sand is a form of artificial sand, manufactured by crushing large hard stones, mainly rocks or granite, into fine particles, which are then washed and finely graded.
It is widely used as a substitute for river sand for construction purposes, mostly in the production of concrete and mortar mix.
