[ 1 ] - A new classification system for evaluation and prediction of unplanned dilution in cut-and-fill stoping method

Production planning in mineral exploitation should be undertaken to maximize exploited ore at a minimum unplanned dilution. Unplanned dilution reduction is among the ways to enhance the quality of products, and hence, reduce the associated costs, resulting in a higher profit. In this way, firstly, all the parameters contributing to unplanned dilution in underground stopes and specifically the c...

[ 2 ] - Risk prediction based on a time series case study: Tazareh coal mine

In this work, the time series modeling was used to predict the Tazareh coal mine risks. For this purpose, initially, a monthly analysis of the risk constituents including frequency index and incidence severity index was performed. Next, a monthly time series diagram related to each one of these indices was for a nine year period of time from 2005 to 2013. After extrusion of the trend, seasonali...

[ 3 ] - Effects of Blast Vibration on Unplanned Dilution in an Underground Metal Mine

One of the factors affecting overbreak or slough of the roof and walls of underground stopes, causing unplanned dilution is blast vibration. The amount of damage caused by earth vibration can be measured in terms of peak particle velocity (PPV). In this study, in order to investigate the effects of blast vibration on the occurrence of unplanned dilution, 72 three-component records acquired upon...

[ 4 ] - ارایه مدلی برای پیش بینی رقیق شدگی غیر طراحی در معادن زیرزمینی فلزی با لحاظ سیستم های مهندسی سنگ

پدیده اضافه شکست و ریزش سقف و دیواره‌های کارگاه‌های استخراج در معادن زیرزمینی، سبب بروز رقیق‌شدگی غیرطراحی و افت عیار ماده معدنی استخراجی می‌شود. مکانیزم پیچیده ایجاد رقیق<...
