A potential application of in-pit crushing-conveying and dewatering system in peat mining

Abstract

The purpose of this paper is to analyse the application of fully mobile plants for raw peat crushing, mixing and separating of wood inclusions and for mechanical dewatering in peat open-pit mines to increase the efficiency of mining. In-Pit Crushing and Conveying Systems (IPCC) which characterized by their economic efficiency, reduction of labour costs, haulage costs, fuel consumption and pollution (dust and noise) compared to conventional shovel-truck systems are well known. Full mobile In-Pit Crushing-Conveying and Dewatering System includes an excavator, two mobile plants: crushing and dewatering plants. The considered technology of primary processing of excavated raw peat has the following advantages: reducing trucks fleet; reducing transportation costs; an opportunity of continuous processing of peat; reducing the energy consumption of the crushers; eliminating the need to build water treatment plants in factories due to returning squeezed water back to the pit.
