ПОРІВНЯННЯ СХЕМ БУРІННЯ І ЗАРЯДЖАННЯ ПІДРИВНИХ СВЕРДЛОВИН З ВИКОРИСТАННЯМ СУЧАСНОГО ПРОГРАМНОГО ПРОДУКТУ MICROMINE

Abstract

Purpose. The effective schemes of rock preparation using drilling and blasting operations in the conditions of Ingulets GOK with help of the Micromine software package were substantiated. The indicators of lineal drilling and charging volumes when using different schemes of placement of holes on the block were obtained. Methods. During the research, a digital model of the Ingulets open pit was created, and a site for research on the creation of holes was selected. A method of analyzing statistical data after calculating the volume of drilling and charging holes with explosives was used. Research results. Using of the Micromine software product allows to take into account the unevenness of the surface on the horizon and the formation of a flat horizon of the next bench through the use of a digital surface of the open pit. With the help of the software package, the optimal parameters of drilling and blasting operations and statistical data on the block of hole charges determined for the study were obtained. Scientific novelty. The use of the Micromine software package and the obtained indicators enabled to establishment of statistical data on the placement of holes in a staggered and rectangular drilling scheme. It allows to determine the most appropriate scheme, taking into account the drilling meterage and explosive volumes when preparing the block for extraction. Practical significance. The established technological schemes for the placement of drill holes on a drilling and blasting block in the conditions of Ingulets GOK allow for reduced drilling costs and planning drilling and blasting operations. It is proposed to set the amount of explosives taking into account the drilling schemes at the relevant horizons using the Micromine software product, which allows to set of average indicators and calculations in a modern geoinformation software product.
