Development Of Technological Schemes For Transporting Rock Mass And Management Of The Working Area Of A Deep Quarry

Abstract

The operating conditions of modern industrial vehicles are determined by the increasing depth of mining operations. This trend results in the predominant use of vehicles (over 60%) as assembly units, concentrating vehicle traffic in the working area of deep quarries with their limited space of the Muruntau deep quarry is characterized by a high concentration of traffic, heterogeneity of the transported rock mass, and instability of key parameters. During a shift, 10-15 working faces and 5-10 transfer points are in operation, forming over 100 routes with an average length of 3.73 km. The maximum freight traffic intensity on individual routes reaches over 35,000 m³ of rock mass per shift. The share of face roads along the traffic routes is 15-30%. Up to 80% of the roads have a service life of up to one year. The complexity of operating conditions is exacerbated by the high concentration of mining equipment and minimal excavation space.
