As shown in Fig. 1 and Fig. 2, the study area is located in Pinglu District, Shuozhou City, Shanxi Province.Pingshuo mining area is the largest opencast coal production base at the end of the 20th century. In order to highlight the research on the land use and ecological response of mining activities, urbanization, and land reclamation in …
A similar solution is also provided for the open cast Moatize coal mine in Mozambique where the water levels must remain low for continuous production reliability. ... In Mexico's Zacatecas silver mines underground water is a constant problem. ... KSB Indonesia launched a new model, the DnD Cruiser with enhancements requested by …
It has 352 mines (as of April 1, 2020), of which 158 are underground, 174 open cast, and 20 mixed mines. CIL further operates 12 coal washeries (10 coking coal and 2 noncoking coal) and manages other establishments such as workshops and hospitals (Ministry of Coal, India).
Lal B. et al., in the paper entitled "Prediction of Dust Concentration in Open Cast Coal Mine Using Artificial Neural Network" [16] developed 3 models for predicting the concentration of dust ...
Undetected faults in heavy earth moving machinery (HEMM) are associated with unwanted failures. Dragline is an HEMM used in coal mining for removal of overburden and dumping it into de-coaled area.
The model has been illustrated with a case study of an opencast coal mine in India. For this mine, the SWR of 22.83 m 3 /t and SEC of 8.97 kWh/t are estimated for rainfall of 100 mm/d. The results show that the SEC increases by 34% from 3rd year in 1998 (6.65 kWh/t) to the 15th year (8.97 kWh/t).
Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones deposits. It often results in high productivity and requires large capital investments, low operating costs, and good safety conditions. The main …
element models, and pre-flawed sandstones are studied. These models assist in evaluation of slopes in open cast mines that are located near stone beds, thereby improving their scalability. Artificial neural networks (ANN) have been applied successfully in slope stability problems (Feng, et. al 2018) [27], however they do have certain …
Dynamic simulations are powerful tools, but only if they are developed using the correct methodology, and with information that has been verified. Mining houses rely on simulation to confirm that complex, integrated systems can achieve design capacity before investment decisions are made. Work conducted in the realm of validation can make an …
The research article presents a reliability-based analysis of probability density function, and the failure rate of a shovel-dumper system was determined based on Weibull distribution in an open cast coal mine. Referring to the bathtub-model along with the Weibull distribution of a shovel and dumpers, decreasing, constant and increasing failure …
Research studies carried out on opencast mine illumination by different investigators are limited in both India and abroad. Mayton [] investigated different surface mining operations in various regions of the United States using visual task evaluation, a method used by the CIE and the IES and data were collected for surface mines and …
The model was designed according to CIE 140/EN 13201 illumination standard and the existing design was as per Directorate General of Mines Safety (DGMS) standards.
Data obtained from 312 measurement stations of sound propagation in panel 48 of the Tuncbilek open cast mine, Western Lignite Corporation, Turkey have been used to create an empirical model for such propagation. As well as the noise level recorded at these stations, atmospheric conditions were recorded also by the meteorological station …
Ground vibration is one of the most undesirable effects induced by blasting operations in open-pit mines, and it can cause damage to surrounding structures. Therefore, predicting ground vibration is important to reduce the environmental effects of mine blasting. In this study, an eXtreme gradient boosting (XGBoost) model was …
This paper details the optimization framework model for managing the schedule of the movable mining equipment of open cast mines to improve the availability and productivity of the mining equipment.
