Open Pit Mining - an overview ScienceDirect Topics

Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow. Figure 8.8. Open-pit mine [16]. Surface mining is usually used to develop coal seams and deposits of many other minerals, but their feasibilities vary with the nature of the body ore.

Production Schedule Optimization in Open Pit Coal Mine

2021-5-20  Abstract: Based on the floatingcone exclusion method and geological model of coal seam, geologically optimum pushbacks were produced in a known final pit of coal mine. A dynamic sequencing model was established and the geologically optimum pushbacks were introduced into it, with the maximum NPV (net present value) as a target function.

Performance metrics were defined for the emission control programs implemented by mining companies. It was found that coal open-pit mines are emitting 0.726 and 0.180 kg of TSP and PM (10), respectively, per ton of coal produced. It was also found that these mines are using on average 1.148 m (2) of land per ton of coal produced per year.

Underground mining is the oldest method of mining coal. From the late 1970s to early 1980s open pit operations increased, achieving high quantities of production and lower production costs. However, today, with environmental considerations and the greater depth of coal seam deposits, underground mining is proving to be the more viable alternative.
