In construction projects, equipment always plays an important role, especially in the heavy and highways segments of the construction industry [1]. Contractors owning a large equipment fleet or plant owners must take ... reliability analysis of mining equipment such as loadhauldump (LHD) machines [1, 16, 17]. In these studies,
Payload, truck velocity, haul road condition, road design, fuel quality, weather condition and truck driver skill are among the important parameters that affect fuel consumption of mining haul trucks.
equipment. Mining engineers can make reasonable estimates of these parameters before modeling and incorporate them into the truck cycle time. In a similar way, the truck cycle time can absorb other parameters such as rimpull, haul grade and haul distance into one estimate. In industry, the
Hauling Equipment 101 Chapter 10 Hauling Equipment The most common hauling equipment used for Army construction work are the 5 and 20ton dump trucks, both of which are organic to most engineer units. Equipment trailers are used to transport heavy construction equipment not designed for crosscountry travel. They are also used to haul long ...

for mining equipments due to following reasons: • Mining is a serial operation of drillingblasting, loading, hauling and dumping. Therefore, the production of equipments used in each step depends on the production of previous equipment. That means utilization of each equipment affects the others. • The capacity of mining equipment is huge.

scale mining projects involve openpit mining, many large underground mines are in operation around the world. Reworking of inactive or abandoned mines and tailings Some mining projects involve the reworking of waste piles (often tailings) from inactive or .
underground mining equipment is specialized and expensive. A number of surface mines operate 24 hours/da y and almost 365 days/year in order to use open pit machinery for as many hours as possible, thereby reducing the number of machines required. In contrast, underground operations are often interrupted by the need
Determine the average grade (in percent) and the distance (in feet) for both the haul and return routes. Uphill grades are positive (+) and downhill grades are negative (). This information will be given or you can obtain from a mass diagram or a haul route profile. Step 3. Determine the rolling resistance (in pounds) for both haul and return.
