Interrelationship of in-situ Rock Properties, Excavation Method, and Muck Characteristics
Abstract
The report gives results of research to correlate the properties of in-situ rocks with materials handling properties of muck from excavation. Goals are to develop methods for predicting muck properties from rock properties 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 MDN's, and equipment selection are described. Results include sample and data collection from fifteen sites. sample testing by commercial testing laboratories and the PMSRC, and development of raw data- printouts, narrative-graphic summaries, tentative MDN's and transport equipment summaries. Samples are classified by operating method, rock strength, and lithology. Program phasing precludes detailed data analysis and final conclusions at the present stage. Curves showing muck size distribution vary distinctly with operating methods, rock type, and rock strength.
