11 Open Pit Mining: is a term properly applied to a surface mining method in which reclamation is deferred until all, or nearly all, of the deposit is removed within economic limits. Open Pit Mining is mostly being worked with shovel dumper combination or FE loader Tipper Combination. Quarrying: is usually restricted to mining dimension stone prismatic blocks of marble, granite, limestone ...
India has reached the forefront of world coal scene, ranking 3 rd in total coal production. It is largely due to rapid increase in contribution from opencast coal mines (presently 89%). The share of dragline operated opencast mine is also more than
the result obtained from the combination of these (ISO 1997). Some work has been developed in task characterization in the mining equipments such as rock drills and shovels. Nevertheless, dumpers are often studied. On one hand, they have the highest WBV .
E) 700. 95) A surface coal mine is worked by 10 m3 shovel – 85 tonne dumper combination. If the shovel bucket fill factor is, the material swell factor is and the average insitu of the material is tonne/m3, the number of shovel bucket loads required to fill a dumper will be nearly. A) 6.

Fig. shows a modified layout depicting the position of various coal and OB benches in a quarry (shoveldumper combination) at an advanced stage if OB is backfilled in the decoaled area. The seam is considered to be 18 m thick dipping at 1 in 5.
Under the prevailing geomining conditions, with multiple seams and steep gradient, it is proposed to mine the property using shoveldumper combination – which is considered most suitable. The method of work with Shoveldumper Mining comprises of – • Removal of topsoil.
in surface mining is by truck and shovel combination. This operation is one of the key factor to reduce the cost of mineral production. This paper presents a complete methodology that can be used to determine the number of trucks required per shovel during striping and the extraction of minerals for Surface mining. The methodology is
Optimization of shoveltruck system for surface mining by Ercelebi*, and A. Bascetin† Synopsis In surface mining operations, truck haulage is the largest item in the operating costs, constituting 50 to 60% of the total. In order to reduce this cost, it is necessary to alloe and dispatch the trucks efficiently.
committee and it was decided to prepare the proposed mine with outsourcing proposition for both coal and OBR for a targeted capacity of Mty. Accordingly the report had been prepared with option of outsourcing of both coal production (extraction coal by surface miner) and OB removal (by shoveldumper combination).
