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