Abstract

When drilling blast wells in the technological process of mining magnetite quartzites, the cost of a cone bit is about 60% of the cost of the entire drilling tool. The work includes a literature review of modern methods of increasing the reliability of drilling tools. It has been established that the main directions for increasing the performance of cone bits are the use of wear-resistant materials and coatings for their production, improvement of drilling technology and the organization of repair and preventive maintenance. In the work, it is proposed to use MATEХ (Canada) drilling chemistry, which has found wide application in the oil and gas industry and in granite quarries during impact drilling. The research was carried out in a quarry for the extraction of magnetite quartzites on an Epiroc DM-75E drilling rig, drilling chemicals were fed into the water-air mixture using a MATEХ dispenser. The drilling chemical dispenser is completely self-contained and easy to install on the drilling machine, designed with only one moving part, which ensures low operating costs. Industrial studies with the use of MATEХ drilling chemistry (the consumption of chemistry was 1.5 liters per hour) showed a significant increase in the working hours of cone bits, on average, from 745 to 1488 linear meters. Conclusions were made regarding the use of MATEХ drilling chemistry in the conditions of iron ore quarries of the private joint-stock company «Northern Mining and Processing Plant» (Kryvyi Rih). Experimental studies showed the expediency of using drilling chemistry when drilling blast wells for the extraction of magnetite quartzites. Due to the increase in the working time of cone bits, a reduction in the cost of drilling 1 linear meter of blasting wells by 38.7% was achieved
