The growth in marble quarrying requires the implementation at mining enterprises new high-performance equipment. In this connection, it is advisable to consider the possibility of use in the development of marble deposits surface milling miners. To improve the efficiency of their operation it is necessary develop a technique of operational definition of surface miners` basic parameters according to conditions existing at marble mining enterprises. Experience shows that when choosing miner`s model the determination of its parameters can be carried out using regression dependences. As a result of processing initial information about technical characteristics of surface miners the dependences determining connection between milling width, engine power and operating weight were obtained.
In the largest Russian Koelginskoe marble deposit during 2014-2015 chronometer monitoring the work of surface milling miner Wirtgen 2500SM were conducted in different modes and conditions. In the study miner`s speed was varied from 7 to 9 m/min and cutting depth from 0.1 to 0.15 m. Surface miner worked according to the shuttle scheme with a turn at the end of the site. Rock was loaded into dump trucks with carrying capacity of 25-30 tons. Processing of observational results allowed to get dependence for the operational definition of miner`s performance in marble deposits developing. A nomogram for determining the engine power, weight and miner`s operational performance with different milling widths was constructed.
Dependences obtained during the study can be used when selecting miner for a particular deposit, as well as when forecasting engine power, operating weight and performance of surface miner`s perspective models
