A dragline system is an unusually large land machine that is used in civil engineering, strip mining, and excavation. The larger types of drag line excavators are used in strip mining operations to extract phosphate rock. These are among the largest types of mobile equipment and can weigh upwards of ten thousand tons A common dragline excavation method is called the key bridges or the key blocks. Variation of this method exists depending on the equipment and the geometry of the deposit. Let's have a look at the main steps of this method. As we can see in this image, at the beginning, we have the surface and he coal seam at a defined depth A dragline bucket system consists of a large bucket which is suspended from a boom (a large truss -like structure) with wire ropes. The bucket is maneuvered by means of a number of ropes and chains. The hoist rope, powered by large diesel or electric motors, supports the bucket and hoist-coupler assembly from the boom

Cat® Draglines Cat draglines offer the lowest material removal cost per ton, consume less power and emit fewer greenhouse gases than other methods of overburden removal, making them the most productive and environmentally friendly excavators in the industry The integrated mining system where truck and shovel is combined with the use of a dragline for overburden removal, provides a system with many benefits. Generally, the truck and shovel system is used to remove the upper and thinner overburdens found within a deposit and the draglines remove the much deeper overburdens, which would be out of the working range of a shovel operation (Aiken and Gunnett, 1990), as shown in Figure 9 Overall mining sequence of a typical surface coal mine in Australia (after Westcott et. al., 2009). 2.1 Dragline method.

The strip mining method continues to mine the overburden below the depth at which the area was area-stripped. Draglines or continuous excavators, which are used to strip the overburden from the lower seams, are large pieces of equipment and require large, level areas from which to work. Draglines and continuous excavators have dig depth. Dragline productivity and its stripping capabilities are directly affect,~d by the selection of digging method, strip layout and pit geometry .Every mine has a unique combination of geological conditions. The operating methods that work well at one mine may not necessarily work at another site Draglines are unique pieces of equipment that have evolved through the development and introduction of new technology, operating practices and mining methods.

P&H draglines from Komatsu have a solid reputation and proven performance in the industry, with boom lengths and bucket capacities available to meet your specific requirements. Our draglines are built with customer-inspired innovations that help optimize rugged, reliable and safe performance The dragline can mine thousands of tons of phosphate rock material every day of the year, due to the dependability factor. The phosphate strip mining is accomplished by various methods of stripping the materials from the ground as illustrated above Dragline excavators in mining are used to remove overburden - anything that's in the way of getting to the real product. For example, removing soil and rock from the surface above the coal seam. This overburden is repurposed, in some cases set aside to refill the open pit when the resources are exhausted Mining of new pits and extensions would be by open cut methods. The mining strips are generally 50 m to 70 m wide depending on depth and other constraints. A maximum dragline dig depth of some 45 m has been applied for all reserve blocks. Waste occurring above this horizon has been allocated to the excavator and shovel fleets It is an effective method of retrieving a higher proportion of coal when compared to underground mining. The basic process involves: 1) Exploration 2) Geological Modelling 3) Mine Design 4) Top Soil Stripping 5) Drilling & Blasting 6) Pre-strip Operations 7) Dragline Operations 8) Coal Mining 9) Rehabilitation 10) Processing 11) Transport 12.

Following the landslide, mining has been accomplished by a combination of dragline, dozer, and truck and loader operations, depending on the depth and material being mined. The overburden, or rock that lies above the coal seams to be mined, is drilled and blasted to break up the rock to allow it to be moved using the mining equipment A general overview is presented relating to cost estimation for conventional dragline, shovel-truck, and scraper mining systems. A short-range equipment selection and long-term evaluation of mining a thick coal seam by each method also are considered. Cost analyses are based on 1977 equipment prices, wage rates, and associated mining costs The U.S. Department of Energy's Office of Scientific and Technical Informatio

Strip mining is done only when the ore body is in close proximity to the surface. Open-pit mining - Open-pit mining is the method in which minerals or rocks are extracted from the Earth via an open pit or borrow. Mountaintop removal mining - Mountaintop removal mining (MTR) is done by mining coal seams underneath mountaintops More specifically, mining is used to extract non-renewable resources like fossil fuels, minerals and even water. There are four main methods of mining: underground, surface, placer and in-situ. The type of mining method used depends on the kind of resource that is being targeted for extraction, the deposit's location below or on the Earth's.

Nearly 60 self-propelled modular transporters, trailers powered [ Overburden removal in US area mining is commonly accomplished with large draglines, stripping shovels, or in small mines, by conventional excavation and haulage (truck-shovel or dozer-scraper) methods. In some other countries such as Germany, bucket wheel excavators are also used to remove overburden. Dozers and scrapers are also used in. Pictured here in 1961 is a Marion walking dragline removing overburden at a coal surface mining operation near Estevan, Saskatchewan. As can been seen in the photo, the Great West Coal Company needed to remove a large amount of material to access the high quality coal seam, and the ideal method was with a large dragline The mining dragline HS 8300 has been designed to meet the tough conditions in mining environments. The machine delivers power and performance with low cost per ton and high turnover rates. The interlock control system allows for power regeneration in dragline operation, reducing fuel consumption as well as wear and tear of the free-fall winch

When the water table is available, or a problem for dry mining, dredging can be a cost effective replacement to dry mining. Common in sand and gravel, deposit information is paramount in determining type of dredge required. Cutter head, jet suction, clam shells, and bucket ladder dredges all have relatively specific deposit applications Dragline Monitoring. Draglines are massive pieces of equipment used in strip-mining operations to remove overburden above coal. They are incredibly valuable assets that require strict maintenance schedules and demand careful monitoring for safe and efficient functioning This means replacing the dump trucks with draglines, while the number of dump trucks used in the deepening longitudinal mining method (5-13, depending on the annual capacity and depth of pit) is higher than the number of draglines used with the continuous lateral mining method (3-11), due to the higher productivity of the latter . At the. Range Diagram. The Range Diagram command is an interactive tool that displays graphics which are dynamically updated when adding or editing values in the spreadsheet text below. This is a quick and easy way to find parameters such as pit width, or to size a dragline to fit the geology. Methods of mining include Side Cast, Dozer Push, Extended. Opencast mining or quarrying of minerals is easier than mining by underground methods. During quarrying the alluvium and rocks below which the minerals lie, are removed and dumped, in the initial stages, in a place which is not required in future for quarrying, residential or other purposes. The mineral exposed is completely extracted

The two mining methods used in coal extraction are surface Open Pit mining and Underground mining. Simply put, surface mining is peeling back the earth and collecting coal near the surface. Whereas, underground mining requires tunneling and building shafts. The mining method chosen by companies depends on the coal deposit being extracted What is Strip Mining? Surface mining, counting strip mining, mountaintop removal mining and open-pit mining, is a wide classification of mining where soil and rock covering the mineral source (the 'overburden') are gotten rid of, unlike underground mining (or deep mining) where the overlying rock is kept in place, and the mineral is taken out through shafts or tunnels Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones deposits. It often results in high productivity and requires large capital investments, low operating costs, and good safety conditions. The main topics that will be discussed in this chapter will include.
