Perspective Technology of Open-Pit Mining of Limestone and Dolomite
Dmitry Nikolaevich Ligotsky and Kristina Vladimirovna Mironova
 
Abstract: This study describes the technology of limestone and dolomite mining which can be used both for deposits with a simple geological structure and for deposits that have an internal overburden-substandard rock lying in the form of lenses and interlayers in strata of minerals that cannot be contoured during exploration and the calculation of reserves due to its non-systemic spread. To date in quarries equipped with a large fleet of various types of equipment, the main technical and economic indicators (productivity, profitability of the enterprise and so on) are rising at an insufficiently high rate. In most cases, this is impeded by the inconsistency between the mining, loading, transporting and auxiliary equipment with the engineering conditions of mining which leads to a low degree of use of such equipment and weak mechanization of auxiliary processes and subsequently causes reduction in quality of the extracted raw materials and technical and operational parameters of the enterprise in general. Therefore, creation of new technological schemes for exploitation of limestone and dolomite deposits with the use of powerful, unified, mobile equipment for mining is of great practical importance for many enterprises.
