چکیده | ||
ماشین های بازویی حفر تونل (رودهدرها) از آن دسته از ماشینهایی می باشند که قابلیت و انعطاف پذیری بی نظیری در حفاری مکانیکی تشکیلات سنگی نرم تا مقاومت متوسط را دارا می باشند، از این رو بطور گسترده در معدنکاری زیرزمینی و تونلسازی مورد استفاده قرار می گیرند. ارزیابی و پیش بینی عملکرد رودهدرها عاملی بسیار مهم در کاربرد موفقیت آمیز آنها محسوب می شود. هدف اصلی این تحقیق، ارائه مدلی برای پیشبینی میزان مصرف تیغه ماشین های رودهدر بر اساس خصوصیات تشکیلات سنگی حفاری شده می باشد. برای این منظور، طی ارزیابی دقیق عملکرد رودهدرها و برداشت های میدانی و عملیاتی مستمر در تونل های اصلی و گالری های دسترسی معدن زغالسنگ پروده طبس، یک بانک اطلاعاتی جامع با قابلیت اعتماد بالا از میزان مصرف تیغه رودهدرها و خصوصیات ژئومکانیکی تشکیلات سنگی مورد حفاری تهیه شد و مورد تحلیل و بررسی دقیق قرار گرفت. نتایج تحلیل ها نهایتا منجر به ارائه مدلی برای پیش بینی میزان مصرف تیغه رودهدرها گردید. نتایج تحلیلها نشان داد که ارتباط بسیار خوبی بین فاکتور مصرف تیغه رودهدر (PCF) و اندیس مصرف تیغه (PCI) با ضریب تعیین (R²=0.94) وجود دارد. نتایج حاصله از تحقیق نشان داد که این سری جدید معادلات را می توان بطور موفقیت آمیزی برای پیش بینی میزان مصرف تیغه رودهدرها در معادن زغالسنگ بکار برد. | ||

چکیده [English] | ||
Roadheaders are one of those machines that have a unique capability and flexibility in mechanical excavation of soft to moderate rock formations, therefore they are widely used in underground mining and tunneling projects. Performance prediction and evaluation of roadheaders are considered crucial factors in successful applications of such machines. The main objective of this research work is to provide a model for predicting the pick consumption index (PCI), an index indicating pick consumption rate, based on the characteristics of the excavated rock formations. For this purpose, a comprehensive database with high reliability of pick consumption indexes (PCI), as well as the geomechanical properties of the rock formations were prepared during the detailed evaluation of the roadheaders’ performance through field and operational observations in the main tunnels and access galleries of the Tabas coal mine project and were then analyzed and examined carefully. The results of the analysis finally yeild a model for predicting the pick consumption index (PCI). The results show that there is a very good correlation between the peak cutting force (PCF) and the pick consumption index (PCI ) with the coefficient of determination (R²=0.94). The results of the research also demonstrated that this new series of equations can be successfully used to predict the pick consumption index (PCI) in coal mines. | ||
