Interrelationship of In-Situ Rock Properties Excavation Method, and Muck Characteristics

Abstract

The report presents results of research to correlate the properties of in-situ rocks with materials handling properties of muck and parameters of excavation systems. Goals are to develop methods for predicting muck characteristics from collected data and for selection of transport equipment through the Muck Designation Number concept. Muck sample, rock, and operating data collection, testing methods, data processing, development of muck designation numbers, regression analyses, and equipment selection are described. Data for 52 samples from 23 mine and tunnel sites are presented in raw data printout and narrative-graphic summary form, showing lithology, rock properties, operating data, muck properties, and equipment applications. MDN are described by composite size and distribution curves, with regression analyses of 47 data sets and prediction accuracies of over 80 percent.
