Drill Rigs In The Mine

1. Introduction The spend discipline was conducted at the Anglo platinum tap in Rustenburg. Anglo atomic number 78 is the largest producer of platinum in the world. During the vacation work the author was assigned a project title A critical investigation into the Wassara boxhole praxis rig, the Technical ideal Controlled (TAC) drill rig and Conventional drop raise at Paardekraal fizgig. This project is a requirement of the School of exploitlaying engineering science at the University of the Witwatersrand. 2. Mine Background Paardekraal gumshoe is one of ten Anglo atomic number 78 excavations that fall under Rustenburg Platinum Mines (RPM) operations. The tap is located around 4km, East of Rustenburg, in the Hesperian limb of the Bushveld complex. anatomys 1 and 2 below illustrate the jam of RPM and Paardekraal shaft respectively. [pic] Figure 1: mending of Rustenburg Platinum Mines (RPM)1 [pic] Figure 2: Location of Paardekraal shaft in the RPM1 T he mine has two take downs; Merensky and UG2, which are mine concurrently. Merensky reef and UG2 are mine at lower and focal ratio take aims respectively. Merensky reef is mine primarily to produce platinum, while UG2 reef is mined primarily to produce chrome. The reefs dip at to the highest degree 9-10º.

The mine consists of 19 levels; first 10 levels are accessed by a vertical shaft and other 9 levels by a decline shaft. Areas of interest for this Project were in level 14, 16 and 18. The main geological features that are found at Paardekraal shaft are shear zones and faults. 3. Project background Traditio nal education of steep-dipping orepasses (! boxholes) is inherently unsafe and will soon be cast out at Anglo Platinum2. Conventional drop raising is a mode by which long hole drilling equipment situated in the raise is used to drill the long leg of an orepass normally towards the end of a stub (dog-leg) developed by traditionalistic methods from the crosscut. The conventional drop raise technique it is an improvement compared with the traditional hand-held...If you want to get a full essay, order it on our website: BestEssayCheap.com
