This paper presents a methodology to optimize the ultimate dump design in a mining operation by minimizing the unit haulage cost using a linear algorithm and subsequent iterations on variables such as the footprint base, number of lifts and haulage distances from the
#0183;#32;Xinyi et al. (2009) investigated Yanma coal mining waste dump in China in their study. The surface layer soil around the mountain was gathered, and the heavy metal content and pH were measured out. The heavy metal (Pb, Zn, Cu, Cr, Cd) pollution situation of the soil was researched according to the distance of coal mining waste dump.

Smart mining market on the basis of type is segmented into, surface mining and underground mining, and automated equipment. Automated equipment is the most popular one due to its ability to evade unnecessary man hours by implying load haul dump, excavators, drill, breakers, and others, for extracting minerals laying on rock or soil.
The South African landscape is filled with mine dumps bearing testament to South Africas rich mining heritage. In laymens terms the phrase mine dump refers to an area where excess material containing forms of mineral(s) were left (either valuable or of no value to the miner) by the person who won the minerals from the earth in accordance with his/her right or entitlement to mine.
The methodology consists of the formulation of a generalized model based on the relationship of the main dump parameters, followed by the use of linear programming to find the solution that minimizes the haulage total cost, and finally through a series of iterations, modifies the preliminary solution by projecting it to the topography and creating the ultimate dump design.

The declining fertility of African soils because of soil nutrient mining is a major cause of decreased crop yields and per capita food production in Africa and, in the mid to long term, a key source of land degradation and environmental damage. Methodology The methodology for monitoring of nutrient mining began by estimating nutrient balance.
