The paper describes a computer procedure for evaluating and selecting recoverable reserves in a mine worked by sub level stoping. The boundaries of the volume to be mined are optimally defined by means of 3-dimensional Lerch-Grossman algorithm, separately applied to both sides of the panels. The procedure which has been developed for Masua Mine (Sardinia), also provides for smoothing the optimized boundaries, positioning the drilling drifts, interactive design of drilling fans and calculation of tonnage and grade of each volley. These tonnages and grades form the input of another procedure evolved for production planning.

Abstract
The paper describes a computer procedure for evaluating and selecting recoverable reserves in a mine worked by sub level stoping. The boundaries of the volume to be mined are optimally defined by means of 3-dimensional Lerch-Grossman algorithm, separately applied to both sides of the panels. The procedure which has been developed for Masua Mine (Sardinia), also provides for smoothing the optimized boundaries, positioning the drilling drifts, interactive design of drilling fans and calculation of tonnage and grade of each volley. These tonnages and grades form the input of another procedure evolved for production planning.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
