Improving a geophysical method to determine the boundaries of ore-bearing rocks considering certain tectonic disturbances

Abstract

Purpose is to improve a geophysical method of determining the boundaries of ore-bearing rocks and tectonic disturbances under complex mining and geological conditions while developing 3D geological models. Methods. 3D geological models of natural objects were developed on the basis of complex structural, geological-geophysical, and lithological facies analysis with the wide use of modern 3D seismic exploration technologies taking into consideration the parameters for prediction and selection of optimal factors for ore deposit development. Findings. The scientifically substantiated result is represented by the increased reliability and efficiency of seismic exploration for singling out the ore horizons and ore bodies as well as tectonic disturbances at different depths by specifying geological structures of the prospective areas and sites under study. Originality. Basing on the carried out studies, methods of the development of 3D geological models to study depth geological inhomogeneities of the ore-bearing complexes under complex mining and geological conditions were improved. Practical implications. The obtained results of 3D modelling of geological media basing on the applied 3D seismic exploration will help increase a confidence factor of scientifically substantiated prediction of ore deposits, provide optimal development of complex ore objects, reduce risks, and increase economic efficiency of solid deposit development under complex mining and geological conditions.

Improvement of the stoping technology in mining magnetite quartzite by underground methods

“…The large number of possible options of sublevel ore caving systems enables their classification [18,19]. When employing a sublevel caving system, the amount of ore losses depends on mining-engineering factors [20].…”

Research of land-saving schemes of mining the horizontal sedimentary mineral deposits

“…Open pit mining is associated with significant disturbance of arable land [1][2][3][4]. In particular, an area of 600-1,800 hectares is disturbed by one mine developing a horizontal deposit [5][6][7][8], which is subject to reclamation after the deposit exploitation [9][10][11][12].…”

Use of laser scanning and 3D software in mining design

“…This data provides a comprehensive understanding of the mining area, aiding in accurate planning and design [6 -8]. Laser scanning allows for the creation of highly accurate as-built documentation of mining infrastructure [9,10]. By comparing scanned data with design plans, it can be identified any deviations and make necessary adjustments to ensure compliance with safety and operational standards [11].…”
