ABSTRACT

Purpose. Definition the advisability of applying environmental-friendly technological schemes for developing solid non-metallic mineral deposits by equipment complexes with conveyor delivery of rock mass and finished products.

The methods. Based on the analysis of previously obtained results of scientific research and technical solutions, efficient technological schemes of environmentally safe development of solid non-metallic mineral deposits with transportation of rock mass and finished products by conveyor transport with full and partial mining of rock mass by modern equipment are determined.

Findings. The environmentally safe development of mineral deposits is advisability of applying by: with complexes of mobile crushing and screening equipment inside quarry with conveyor delivery of pre-crushed rock mass to surface crushing and screening equipment, with conveyor depths from 60 to 82 m; with complexes of mobile crushing and screening equipment, on which complete processing of the rocks is carried out inside the quarry with transportation of finished products to the surface by conveyor transport, with a conveyor depth of 85 to 130 m.

The originality. Based on a comparison of various technological schemes for the development of non-metallic deposits, rational environmental-saving technological schemes for the extraction of mineral raw materials and their processing into finished products are determined and their application area is established.

Practical implication lies in the justified technological parameters of the use of complexes of equipment for the extraction and processing of non-metallic mineral raw materials when exporting it from quarries by conveyor transport. The application of the proposed technology schemes for the development of non-metallic deposits with inside quarry processing of raw materials will reduce gross emissions of harmful substances and localize them in the worked out space of the quarry.

Keywords: technological scheme of development, mobile crushing units, mobile crushing and screening equipments, conveyors, overloading of rock mass and products.
