What is an LHD in mining?

What is an LHD in mining?

DNK10F belongs to a group of LHD (load haul dump machine) machines that have been developed for the toughest rock mining applications, with overall flow economy, safety and reliability.

What is underground LHD?

An LHD is a mid-sized (up to 60 tonnes) underground mining vehicle that loads, hauls and dumps (hence its name) metalliferous ore from an open stope (where there is broken rock) to a crusher or waiting truck to be transported to the surface.

What is a LHD loader?

Caterpillar offers a range of Underground Mining Loaders to match mineral conditions and maximize productivity. A range of size options and configurations (including Ejector Bucket options) are available to suit your specific needs.

What is underground loader?

Underground mining Loader is mainly used for mineral transportation in mines, narrow tunnels and tunnel construction.

What is SDL and LHD?

• Side Discharge Loader(SDL) • Load Haul Dump(LHD)

What hydraulic fluid is needed for LHD?

Safety provisions. Service, emergency, and parking brakes with fire-resistant hydraulic fluid are used. Headlights, audible warning signal, backup alarm, and portable fire extinguisher are provided. A special cabin is also provided for the safety of the operator.

What is loading in mining?

The purpose of the loading and hauling stage is to move the material previously fragmented by the drilling and blasting process. The first step in this process consists of loading the material from the bench or working face of the mine into trucks.

What is the maximum suitable hauling distance for SDL?

best way to improve SDL productivity is to keep the lead distance in the range of 6 to 9 m and at any time it should not exceed 18m during any shift.

Can I mix hydraulic fluids?

CAN I MIX HYDRAULIC FLUIDS? As far as possible, it is always best to avoid mixing different hydraulic fluids. This is because the technical properties could be spoiled by chemical reactions between different additives.

Why is open pit mining safer?

Open pit mining does offer some advantages over traditional deep shaft mining. Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. The working conditions are safer for the miners because there is no risk of cave in or toxic gas.

What is haul mining?

A haul road (also haulage road or haul track) is a term for roads designed for heavy or bulk transfer of materials by haul trucks in the mining industry. It is also used for freight-only roads in other contexts, for example in South Boston leading to Conley Terminal.

What type of hydraulic fluid is required for the operation of LHD?

Can you use motor oil in hydraulic system?

Engine oil can work satisfactorily as a hydraulic fluid. However, if a multigrade engine oil is being used in the hydraulic system specifically for its high viscosity index (VI), then it’s not the correct solution. The reason is the additives used to improve viscosity index.
