To realize economic dynamic assessment and optimization of production capacity of an open-pit coal mine with the balance of the total amount of stripping, Zhang et al.23 surface mining methods; open pit planning and design; open pit terminology; stripping ratio; factors governing strip mining; (PDF) Surface Mine Design ResearchGate
Large amounts of water in the pit causes disruption in excavation and loading and hauling activities. Therefore, the design of mine drainage systems is required. The purpose of the study is toBefore the computer technology was applied to the underground coal mine systems, various types of geospatial information, such as coal seam, roof and floor, Development of coal geological information technologies in China
This study evaluates the situation of green mine construction in China and suggests a future framework. First, based on the Abstract The history of coalfield geology and mine geology IT applications is over 30 years, which is gaining remarkable achievements. This paper sheds light on the Development of coal geological information technologies in China

Table 1 illustrates the survey text file of borehole data. It consists of hole ID, depth, dip, and the azimuth of a borehole. Table 2 shows the collar text file of borehole data. It is made of hole ID, coordination of hole, and depth. Table 3 represents the assay of borehole data. It consists of borehole id, depth regarding average components such as for the Mine Design exercise, in 1997 a new course, ‘Computerised Mine Design’ was introduced in the third year in partnership with some of the leading mine planning software providers. In this course, the students are taught to use specific mine planning software so that it can be used in the following year during the Mine Design exercise. %v118n8a9 Mine Planning and Design for Mining Engineering

Area mining is a surface mining method that allows for efficient mining and contemporaneous reclamation of tabular or bedded deposits, e.g., coal. Mine planning methods for area mines differ from those of open pit metal mines. Area mines in the Powder River Basin (PRB) use various processes for mine planning at both the strategic and GUIDELINES FOR THE INTEGRATED PLANNING AND DESIGN OF UNDERGROUND COAL MINES. G. Fourie, D.

Abstract and Figures. This paper describes a case study for the ventilation planning at TKI Company's Omerler B Mine in Tuncbilek coal basin which is located in Kutahya region in central TurkeyThe concepts of mine planning and design has been reported in long term production scheduling in both opencast and underground coal mines (Campell, 1994; Department of Minerals and Energy, 2001; Fourie and van Niekerk, 2001; Smith and Pearson-Taylor, 2006; Steffen, 1996). According to Brophy et al. (2008), there is a particular focus on design[PDF] Mine planning and design for mining engineering learners at Wits
2. Design an optimal pit outline and develop the long/short term mine plans with cut-off grade optimisation. 3. Explain engineering aspects of surface coal mine planning, development and operation. 4. Explain the factors considered in underground mine planning for coal and metaliferous mines. 5.Mae Moh mine, the biggest coal mine in Thailand, produces annually around 15 million tons of coal with about 6 bank-m3/t of average stripping ratio. The final depth of floor is planned at 250m below the surface. Other four coal mines produce annually around 400,000 to 1,300,000 tons of coal with about 4 to 6.5 bank-m3/t of average stripping ratio.5. Conceptual Planning of Mine Development JICA
