After washing and other arrangements the grade Coal converted to G9 G12 washed G9 grade coal, after weighment on 60T Lorry weighbridge,
This paper presents a reliability analysis of LoadHaulDumper (LHD) in an underground coal mine. The goodnessoffit distribution of each LHD was made through the CramerVonMises statistic test.
Approximately, 40% of the total energy used in surface mines is related to diesel consumption. Truck haulage is responsible for a majority of this. This chapter introduces the principal equipment used to load and haul materials in mines, namely trucks, electric rope shovels, hydraulic excavators and crushing and conveying systems.
truck arrive for loading and the rate of truck service by shovels, justified and defined in [7, 8]. The results of calculating the functional criterion are summarized in Table 2. Table 2. The results of calculating the functional criterion for assessing the STS operation quality at openpit coal mines Indicators Mines
Most notably these include highwall mining machines, load haul dump vehicles (LHDs), rock drills, and haulage trucks. ...

The machine is very useful in mines where seepage is excessive or where rain water forms muck, or where coal pillars are extracted by opencast method. It is quite convenient for cutting garland drains and sump. In Indian coal mines only small backhoes of capacity to m³ are used for special purposes stated above.
LHDmachines are used to load the trucks at the loading bay as shown in Figure 2. When there is no truck to loadLHDs haul the material and, it on a stockpile. Loading time per pass dump includes bucket travelling time when empty, digging time, bucket travelling time when loaded, and loading
Coal is the major source of power in India and world over. Coal mining is an essential industry which has a major role in the economic development of the country. Most major mining activities contribute directly or indirectly to air pollution. Coal dust is a major air pollutant which affects the personal working in the mines and also people residing in villages near the mines. Air pollution ...
Abstract. Robots are being utilised for mining applications since 1976. However, since 2002, robots are widely into mining from conception to end product or even endusers. Lidar sensors connect robot with a realtime map making it travel safely but detects and avoids obstacles on its own. Autonomous Mobile Robots (AMR) are widely used to ...

The open pit mining load and haul system has been a mainstay of the mining industry for many years. While machines have increased in size and scale and automation has become an important development, there have been few innovations to the actual load and haul process itself in recent times. This research highlights some of the potential productivity and safety benefits that the incorporation ...

Both LHDs and mining trucks (figure 2) can be used in underground mines and fitted with automatic systems. However, while the former have a bucket and can therefore load the ore/minerals, the latter can be used only for transportation. In open cast mining, it is common to use larger trucks than those used in underground mines.
The first doublepower transmission mining truck for use in an underground mine was designed in China for a full load of 35 t, a speed of 25 km·h −1, and a maximum climbing slope of %, as shown in Fig. 14. In addition to its unmanned driving function, the truck is capable of vehicle lanespace detection and intelligent auxiliary driving ...
2. The Collinsville Coal Mine equipped with high precision guidance from GPS. 3. Arizona mine uses localised network which uses different highend computer networking system. It tracks the movement of each truck and shovel and then decide when a shovel will need a truck to load, and which truck will be nearby.
To answer the need for material transportation in the coal mining industry as efficient and tough, Articulated Dump Truck (ADT) is used. As known Articulated Dump Truck is a variant of the offhighway truck where the cabin and the back of the dump truck including dump body can be articulated to adjust the extreme field conditions.
The truck dispatching problem in openpit mines is formulated into an integer programming problem in order to optimally determine the trip numbers of trucks from a shovel (dump site) to a dump ...
Autonomous Haulage Systems (AHS) are considered a cheaper, safer, and more reliable option to run the mines by mining companies, especially those in the Americas, Australia, and Europe since the cost of the workforce is high or there is an increased risk in the terrain. In addition, autonomous haulage systems will improve efficiency and ...
Miners, mine operators, and contractors have important roles to play in mine safety. Mine safety can be substantially improved by preventing accidents that involve powered haulage equipment. Accidents involving powered haulage equipment have historically accounted for a large number of the fatalities and serious injuries in mining.
