    Diggability A Measure Of Dragline Effectiveness And

    Dec 01, 1996 Abstract. Given the capital intensity of the dragline operation coupled with rising cost of explosives, the onus is on mine operators to make maximum use of explosives in blasting to assist dragline diggability. At a surface coal mine in South Africa, large boulders necessitating secondary breakage and in some cases completely unfragmented sections of a blast resulting in low dragline

    Derivation Of A Diggability Index For Surface Mine

    Aug 01, 1984 This work relates a method developed in surface coal mines to derive a diggability index based upon rock mass parameters and related to equipment capabili- ties. PRIOR DIGGABILITY STUDIES Diggability prediction has traditionally been based on intact rock strength and dis-

  • Derivation of a diggability index for surface mine

    Derivation Of A Diggability Index For Surface Mine

    The work was conducted in operating British surface coal mines and presents a technique for diggability assessment in that mining and geotechnical environment. A diggability index is proposed which consideres both ground conditions and excavating equipment capabilities. This is supported by reference to back-analysis of several mine excavating case studies.

    Jun 14, 2019 equipment selection in surface mining is primarily depends on determination of ease of excavation in site. The assessing of ease of excavation of rocks has been based on empirical and intuitive processes. Traditionally the problem has been reduced to determining whether blasting or ripping is required prior to mechanical excavation.
