Working Below Ground Level Coal Mining and Quarrying
2019-9-13 Quarrying is even older than coal mining. Local stone was often suitable for building or slating a roof or for field walls and was widely exploited such as at Smithies Lane and Cawley Lane, Heckmondwike. Flags were produced in Quarry Lane where Hightown View now stands. Clay pits supplied brickworks; one is shown at White Lea Road and another

Opencast Mining (Quarrying): Methods, Advantages
2022-2-2 Opencast mining or quarrying of minerals is easier than mining by underground methods. During quarrying the alluvium and rocks below which the minerals lie, are removed and dumped, in the initial stages, in a place which is not required in future for quarrying, residential or other purposes.
