ANALYSIS OF SCHEMES OF BLASTING HOLES AND THEIR IMPACT ON THE QUALITY AND EFFICIENCY OF MINING CRUSHED STONE RAW MATERIALS
The factors which impact on efficiency and quality of drilling and blasting operations are analyzed, namely advantages and disadvantages of different schemes of wells locations during mining of crushed stone are considered as well influence of line of the least resistance on output of oversized and amount of crushed rock are analyzed.
Проаналізовано фактори, що впливають на ефективність і якість буро-вибухових робіт, а саме розглянуто переваги і недоліки різних схем розміщення свердловин при видобуванні щебеневої сировини та вплив лінії опору по підошві на вихід негабариту і кількість переподрібненої породи.
Introduction. Deposits of various rocks, which are used for the production of rubble stone and crushed stone, are known in all geostructural regions of Ukraine. Crushed stone raw materials are performed from a strong and highly abrasive magmatic rock. The extraction of this type rocks is associated with labor-intensive drilling and blasting operations. The disadvantage of drilling and blasting operations is oversized. Oversized, which is subject to secondary crushing, has large volumes because the volumes of mineral extraction increase. Oversized occupy a fairly large area of pit faces, which makes mining difficult.
The analysis of researches and publications. The method of performing explosive borehole work with deviated holes was invented by O. Shapurin and Ya.Vasylchuk [1], described by V. Kravets, V. Vorobyov and A. Kuzmenko [2]. An analysis of the influence of the layouts of explosive wells on the effectiveness of conducting explosive drilling operations in the production of buto-gravel raw materials O. Kisel and A. Kisel [3]. Undercity works were described by V. Kravets, V. Vorobyov and A. Kuzmenko [2]. The physical processes of the applied geodynamics of the explosion were studied by V. Kravets, V. Korobiychuk and V. Boyko [4].
The purpose of this work is to analyze schemes of blasting holes and their impact on the quality and efficiency of mining work, namely reduction of oversized pieces and crushed rock amount.
Materials and research results. Drilling and blasting work is the main method of destruction of rocks during their mining. Thus, with the help of drilling and blasting operations, about 70% of the volume of minerals is mined, 90% of all mining operations are produced by mining enterprises.
Line of the least resistance (W) is the horizontal distance from the axis of hole of 1st line to the bench bottom. For reducing W drilling holes should be done at a certain angle (for different rocks, the angle is different), thus, in the process of mining the output of oversized pieces decreases, the quality of crushed rock improves, due to which the unobstructed work of the extraction equipment is carried out. As a result, technical and economic indicators increase. Also, by reducing the value of line of the least resistance, costs to re-crushing of rocks reduces. The holes of the first line must be drilled at an angle that corresponds to the angle of natural slope of a certain rock. The holes of the following lines respectively approach to 90°. The deviation of well from horizon in the right direction at 1° increases the productivity of production, that is, maximize the output of rocks (Fig. 1).
Conclusions. After analyzing of different drilling explosive holes schemes and the influence of line of the least resistance, which can be reduced by the precise drilling of the deviated holes, it is possible to make the following conclusions that the application of the chess scheme of holes and the optimum evaluation of line of the least resistance reduce the output of oversized, reduce the quantitative loss of raw materials by reducing the extra crushing of rocks, improve the quality of the final product.
