The general focus of our method is justified by the fact that the quarrying sector does not generate revenues to the same degree as the metals or energy mining industries, and so it is not normal for rockfalls to be taken into account in quarry design and operation—despite the fact that rockfalls are the main cause of accidents in the quarry .

Chapter 5 Engineering Properties of Soil and Rock 51 Overview The purpose of this chapter is to identify, either by reference or explicitly herein, appropriate methods of soil and rock property assessment, and how to use that soil and rock property data to establish the final soil and rock parameters to be used for geotechnical design
A quarry is an area from which rocks such as marble, limestone, and granite are extracted for industrial use Once depleted of their desired resources, quarries are frequently abandoned The resulting gaping holes can fill with water and form dangerous quarry lakes while others are turned into unsightly landfills
Design Process Although the nature of quarry design may be profoundly different from site to site the process by which it has been arrived at and the various elements should be clearly laid out in the Health and Safety documentation Good practice would ensure a named individual is responsible for the maintenance of the design
Method is suitable for bulk minerals where there is plenty of out of pit tipping space for overburden, soils, waste and stock storage, or in small sites where method 2 is impractical Open pit quarry - method 2 3 2 1 A void is created to the full depth of the deposit (1) and then full faces are advanced (2) then (3) at multiple bench levels
The method has to be chosen right in the beginning The choice will depend upon the size of the quarry, the nature of the rock and the demand for building ston (ii) Preparation of a layout: In accordance with the method selected for quarrying of stones, a scheme or layout for quarrying will be prepared

The Rational Method , Therefore, a number of methods for estimating a design discharge, that is, the maximum value of the ﬂood runoﬀ hydrograph, have been developed The rational method is a simple technique for estimating a design discharge from a small watershed It was developed by Kuichling (1889) for small drainage basins in
