Abstract
This article presents the geological and stratigraphic features of the Dashkesan iron ore deposit, mineralogical composition, research history, industrial significance, calculation of well coverage parameters, organization of drilling and blasting operations, optimal design of the well network, well placement, organization of determining the distance between them and in accordance with the geological characteristics of ore. The role in this period is analyzed on a scientific basis. The goal is to comprehensively assess the potential of this field and provide recommendations for further development strategies. The purpose of the article is to select suitable technologies and equipment for drilling operations and efficient ore mining, accurately calculate the type and amount of materials used in blasting operations, draw up a blasting scheme so that the rock is crushed in accordance with standards, as well as minimize the impact on the environment. Safety measures should also be in the foreground, blasting should be carried out in accordance with international standards, personnel should undergo the necessary training. The correct definition and application of these parameters increases the efficiency of mining operations, reduces losses and ensures safe working conditions [1]. Cutting ore means separating the ore from the mass and grinding it into parts of a certain size. When mining ore, the following requirements must be met: safety of work, full extraction of ore along the contour, ensuring normal grinding of ore; minimum number of parts requiring repeated crushing; pay for productivity in accordance with the intensity of the unit, low labor costs; cheap cost, etc. The method of extracting the ore depends on its hardness. The exploitation of ore deposits is dominated by solid minerals. The mechanical method is promising for use in coating ores with a hardness of f = 6-8 [2]. The explosive method is first covered with sewage, mine emissions in hard and harder ores, and then wells. Filling ore with wells practically eliminated the method of demining, replacing a certain part of the filling with sewage.Explosion protection on hard ores expends less energy than other methods and is considered the main method for a certain period of time (over the past 20-30 years). Selfremoval of ore is used only in aircraft systems. The hydraulic extraction method is used in the development of horizontal deposits of salt and manganese of small thickness. The electrophysical method is under experiment. The ore extraction process is carried out in several ways. Such methods include: explosive ore recovery; 2. Backfilling with waste water Backfilling with wells, backfilling with mine emissions, mechanical backfilling, self-removal of ore; Hydraulic coating; Electrophysical coating. The paper discussed the well coverage process. Mining at the Dashkesan iron ore deposit, located in the Dashkesan region, which is the largest complex of iron ore deposits in the region, began in the USSR. To this end, the Dashkesan mine administration was created in 1945. 9 years after the creation of the department, the production of iron ore concentrate began. At that time, the processing of iron ore concentrate produced here was carried out in the Georgian city of Rustavi. In differentyears, the enterprise worked under different names, with certain interruptions in the subordination of various institutions and structures.
