Technique for determining the actual parameters of the swing angle of the dragline dragline ESh 10/70 under the conditions of the new scheme mining of pits of refractory clay PJSC "Vesсo"
Purpose. To introduce systematic monitoring of the actual angles of rotation of the dragline boom during field development and to determine the actual parameters of the cycle during excavation and movement of rock mass in order to study the parameters of the implemented mining scheme, and confirm the feasibility of its application. Research methodology. The study of the actual angle of rotation was carried out using a hardware and software calculation method based on data from devices for recording the spatial position of the boom and on the basis of a GPS signal during operation. Actual performance is based on a survey report for the period. Research results. The boom position was measured while working in the open pits of the Andriivske field, and the frequency of manifestation of various angles of rotation was determined. Compared with the planned parameters of the mining scheme. The actual performance for the period has been determined. As a result of the research, the confirmed target indicators of the implemented mining scheme with the EШ10/70 dragline from one position, with re-movement coeficient and contouring of the clay layer, and the angle of rotation up to 220о. Scientific novelty. The complex of studies of the first introduced mining scheme makes it possible to assess the fulfillment of the conditions and the achievement of results to reduce the preparation time for the seam, reduce the overshoot coefficient at boom angles, which were considered ineffective when moving rocks to dumps with a non-transport technology. The positive conclusions of the research make it possible to recommend the use of such a scheme in the development of flat deposits of nonmetallic minerals. Practical value. The technique is stated which can be applied when observing the operation of draglines and other single-bucket excavators in order to determine the parameters of the work cycle and further optimize productivity.The proposed method allows to perform the analysis of the working scheme of the excavator, which leads to the maximum productivity of the mining transport equipment during direct work.
