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 diggability

Derivation Of A Diggability Index For Surface Mine

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

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.

Wms 456 Iphar Continuous Rating For Diggability

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.

An Application Of Fuzzy Sets To The Diggability Index

Feb 01 2006 The determination of the ease of rock excavation is one of the critical stages in surface mining and civil engineering projects. On many projects the ease of rock excavation is mainly based on whether the rock can be economically excavated by mechanical excavators or drilling and blasting is

Prediction Of The Rock Mass Diggability Index By Using

May 09 2013 In surface mining and civil engineering projects terms such as diggability rippability excavatability and boreability are widely used to assess rock mass excavation methods and required equipment. The rippability index was defined for assessing overburden loosening by

reserves which exist near the surface are mostly depleted. Because of the increase in cost which is caused by increasing depths in surface mining larger equipment capacities have been necessary. The huge amounts of material to be dug and hauled especially in dispersed low grade ore deposit have required bigger and heavier mining equipment.
