3.6 PROJECT DESCRIPTION WITH PROCESS DETAILS

3.6.1 Method of Mining

The quarrying in the sanctioned area is of open cast method by semi-mechanized way.

Considering the technical parameters like surface topography, quality variations, geo-

technical aspects are required for production and extraction of building material in the area.

It is proposed to work from the deposit by adopting benches formations with ultimate pit

slope of 45°. Only Jack Hammer, drilling is required for controlled blasting to break the

insitive sheet rock. The benches height and the width will be maintained as specified by

D.G.M.S. The width of the working benches shall not be less than the height. The year wise

production and development plan indicates the site for disposal of waste, site for afforestation

as shown in map. The plan showing position of the working pit proposed for extension etc.

Due care has to be taken in designing the benches and advancing the benches for production.
