ABSTRACT
Purpose. To study the technological scheme of placing a backhoe excavator at the working site when extracting amber-containing mass with loading into a semi-mobile enrichment plant and to establish the operating parameters of the excavator, taking into account the trajectory of the excavator's movement and the location of the enrichment plant.
The methods. Analysis of the technological scheme of amber extraction, graphical construction of the operating scheme. Spatial modelling of the position of the extraction and loading equipment relative to the semi-mobile enrichment plant.
Findings. The technological schemes of loading equipment operation were studied, which made it possible to obtain the angles of rotation of the excavator base with a bucket from the working face to the semi-mobile enrichment plant. Graphical dependencies of the bucket rotation angles when working at the face near a semi-mobile enrichment plant were obtained, and the dependence of the change in the length of the section of the amber area when using JCB 220 excavators with a conventional boom and arm and with an extended JCB 220 long reach arm. The work is the first to determine the dependence of the section length on the length of semi-mobile enrichment plants of different capacities. It has been established that as the height of the ledge increases, the minimum length of the section decreases, and this is due to the fact that an increase in the height of the ledge leads to a decrease in the scoop radius of the excavator with an extended arm.
The originality. Technological schemes for the operation of equipment in amber extraction have been determined, which made it possible to study the angles of rotation of the excavator base with a bucket from the face to the semi-mobile enrichment plant. The mathematical dependence of the length of the section (block) when forming the working area with two excavators and the placement of a semi-mobile enrichment plant has been determined.
Practical implementation. The angles of rotation of the excavator base during amber extraction from the face were determined and the length of the section was established when using different types of semi-mobile enrichment plants.The justified parameters will enable the efficient use of extraction, loading, and processing equipment under the conditions of operating amber quarries.
Keywords: mining operations, technological development scheme, amber, technological parameters, semi-mobile enrichment plant, deposit development.
