Selection of Loading and Haulage Equipment Calculations for selection of Shovel Excavator (Loading and Haulage Equipment) Practical consideration of the following three factors is important in choosing the right size of a shovel or any single bucket excavator: Time factor Operational factor Bucket fill factor
This study established a truck dispatching model adopting 01 decision variables to rationally allocate truck transportation in openpit mines, maximize the total loading and unloading volume of trucks, and solve the problem of the inability of the truck dispatching model to guide production in openpit mines because of nonspecific results. The model considers loading and unloading logical ...

In this paper, we assess the potential of highcapacity coal trucks to reduce costs and scope 3 emissions at Eskom. We consider a scenario in which all the approximately 2000 trucks transporting coal for power stations are transitioned from standard 56t vehicles to 74t PBS vehicles such as those already participating in the PBS pilot project.

If Truck B was loaded straight after Truck A left the loading unit and takes 15 minutes to complete the clean cycle, it will have to queue for one minute behind Truck A at the loading unit. This simplified scenario assumes that all trucks are always allocated to the same circuit. Naturally, load and haul operations are far more complex.
Wagon Loading Systems. Our wagon loading systems are able to reach a capacity of 8,000 t/h and boast charge accuracy to within +/ %. In systems where high material flow rates are required and/or which involve high charge accuracies and/or a high degree of automation, loading systems that include surge and weigh bins can also employed.
Detection of the loading volume of mining trucks is an important task in open pit mining. Aiming at the addressing the current problems of low accuracy and high cost of the detection of the loading volume of mining trucks, this paper proposes a mining truck loading volume detection model based on deep learning and image recognition. The training and test data of the model consists of 6000 sets ...

Every year billion tons of coal are burned in the, with 90% of that being used for electricity generation. Several years ago, a University of Illinois professor reported that to produce 109 kWh/year of power, a plant burns 14,000 tons of coal every day. He noted that the coal that goes to a typical coalfired power plant is crushed to approximately 5 cm in size before it is loaded ...

Shoveltruck systems are a prevalent loading and hauling system in surface mining operations. The loading units are typically wheel loaders (WL), hydraulic excavators (HEX) or rope excavators. The trucks can be offhighway trucks (OHT), articulated dump trucks or coal haulers as in coal mining. Generally truck fleet sizes increase with
function is to receive the material from the shovel and to then load trucks [21]. It thus serves as an intermediary between the shovel and the truck. The result is an increase in the safety and productivity of the loading and hauling stage, as it divides the cycle of the ShovelTruck system into two independent cycles [21] as shown in Figure 2.

The truck flow planning scheme is to dispatch all available trucks for coal mining operations. As a result, there are too many trucks and long queues at the electric shovel, causing serious waste of production capacity. Truck Transportation. Truck is the key equipment of transportation in openpit mines.
