摘要

目的。引入现场开发过程中曳绳臂实际旋转角度的系统监测,确定开挖和岩体移动过程中周期的实际参数,以研究所实施采矿方案的参数,确认其应用的可行性。研究方法。根据吊臂空间位置记录装置的数据和运行过程中的GPS信号,采用软硬件计算方法对实际旋转角度进行了研究。实际执行情况以该期间的调查报告为依据。研究的结果。在Andriivske油田露天矿工作中,测量了臂架位置,确定了各转角的表现频率。与规划的采矿方案参数进行了比较。这一时期的实际业绩已经确定。研究结果表明,所实施方案的目标指标确定为:EШ10/70曳绳从一位置开始,具有粘土层的再移动系数和轮廓,旋转角度可达220°。科学的新奇。通过对第一种采矿方案的综合研究,可以评估条件的实现情况和取得的成果,以减少煤层的准备时间,降低臂架角处的超调系数,这在用非运输技术将岩石移到排土场时被认为是无效的。这项研究的积极结论使人们有可能建议在开发非金属矿物的扁平矿床时使用这种方案。实用价值。该技术可以应用于观察拖斗和其他单斗挖掘机的运行情况,以确定工作周期的参数,进一步优化生产率。提出的方法允许对挖掘机的工作方案进行分析,从而使采矿运输设备在直接工作时的生产率最大化。

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.
