• In this thesis, results of a comparison study of rope shovels and hydraulic excavators undertaken by the author between September 2014 and May 2015 is presented. The study was implemented by a literature search, collecting data from KMG (Komatsu Mining Germany) which is the Komatsu Limited manufacturing facility for super large hydraulic mining shovels (16 to 42m3 Bucket Capacity) in Europe, and receiving and analyzing information from a coal mining company about performance parameters of rope and hydraulic shovels with bucket capacities ranging from 10 up to 33m3.
  The objective of the study is to compare the effectiveness of two types of excavators in surface mining during their life cycle from 0 up to 60,000 operational hours. Each machine performance was surveyed on a month by month basis and involved assessing such parameters as: operational hours, scheduled inspections and maintenance, unscheduled repairs, number of failures, production. Consequently it allowed calculating general indicators to have to be priced in the study and their change with increase of total operational life. These indicators were: physical availability and hourly output of an excavator (normalized to 1m3 of bucket capacity). Moreover, expenditures related to possession of mining shovels (spare parts, fuels, lubricants, electricity, consumables) were also taken into consideration to calculate and compare life cycle costs of machines.
