ABSTRACT
This paper describes the study realized by the Dipartimento di Ingegneria Idraulica Ambientale e del Rilevamento of the
Politecnico di Milano in order to define the most suitable procedures to carry out the survey and the calculation of the
volume of the quarries.
In the first step of the research it has been set up the theoretic aspects of the problem and it has been focused the
methodology, as explained in the paper.
In the second step it has been built up the application and experimental phase: due to this aim it has been chosen three
typologies of quarries. Particularly it has been decided to work on one open quarry, on one quarry at the ground water
table at the stratum superficial and on one quarry with mixed and different characteristics. These three samples don’t
exhaust the whole of the possible case studio but define a generalisation to which all the surveys of a quarry can be
traced back.
Particularly it is here related the different surveys phases, from the realization of the network to the survey of the detail,
using advanced instruments and technology. The reliability of the output of the survey is the condition to obtain to
support the valuation of the volumes and the analysis of the variation in the time in function of the subsequent surveys
at the different temporal phases.
A standard and appropriate methodology can become an agile real time instrument for the advancing of the extractive
activity: GIS technology could be used by both public administration and private subject to of the work organization and
of control in the time.
THE RESEARCH
The research here related is the result of a collaboration
contract between the Dipartimento di Ingegneria Idraulica
Ambientale e del Rilevamento of the Politecnico di Milano
and the Locai Government of the Provincia of Milano in
order to define the most suitable procedures to carry out
the survey, the calculation of the volume of the quarries
located in the territory of the Provincia and the GIS data
management to support the control in the time of the area
of extraction. For this matter three sample quarries has
been chosen in order to allow to focus and solve the
different problems that can be met during the work.
The quarries cover different areas (from 15 hectares to 35
hectares). The procedures here tested and suggested
