New technology for mineral deposits prediction to identify prospective areas in the Zhezkazgan ore region

Abstract

Purpose. Exploration and predicting the prospective areas in the Zhezkazgan ore region to set up detailed prospecting and evaluation works using new integrated technologies of prediction constructions in the mineral deposits geology. Methods. An integrated methodological approach is used, including methods for deciphering the Earth’s remote sensing (ERS) data, the use of geophysical data and methods of analogy and actualism. All constructions are made in accordance with the principles of shock-explosive tectonics (SET). Prediction constructions are started with the selection of remote sensing data for the studied region and interpretation based on the processing of radar satellite images obtained from the Radarsat-1 satellite. The radar satellite images are processed in the Erdas Imagine software package. Findings. New local prospective areas have been identified, within which it is expected to discover the deposits. Their reserves are to replenish the depleted ore base in the Zhezkazgan region. Area of the gravity maximum 1 (the Near), considered to be the most promising, is located in close proximity to the city of Zhezkazgan; area of the gravity maximum 2 (the Middle); area of the gravity maximum 3 (the Distant-Tabylga); area of the gravity maximum 6 (the Central). A prospective area has been also revealed, overlaid by a loose sediment cover and located inside the Terekty ring structure, as well as the area of a thick stratum of pyritized grey sandstones, which is adjacent to the Sh-2 well drilled to the south of the Zhezkazgan field. Originality. The use of a new prediction technology, in contrast to the known ones, is conditioned by the widespread use of the latest remote information from satellite images, which increases the accuracy of identifying the prospective areas of fields. Practical implications. The new technology for predicting mineral deposits makes it possible to significantly reduce the areas exposed to priority prospecting, which provides significant cost savings.

“…The main idea of the presented paper consists in finding a shape that would make it possible to avoid formation of areas of high compressive stresses which, as a rule, are concentrated around the corner areas of the rooms. It is also necessary to avoid emergence of areas of tensile stresses that are the most dangerous due to the fact that the tensile strength of rocks is an order of magnitude less than the their ultimate compressive strength [28,[31][32][33][34][35][36].…”

Geometrization of Kryvbas iron ore deposits

“…A significant task of subsoil geometrization consists in increasing efficiency of drilling and blasting as an important factor for mining enterprise performance [28][29][30][31][32]. This task, in turn, is associated with that of monitoring the state of the rock massif [33][34][35][36][37] and closely related to methods of mining processes control [38][39][40][41][42].…”
