Spontaneous combustion of carbonaceous shale at an iron ore mine, South Africa
نویسندگان
چکیده
Spontaneous combustion during coal mining operations is a major problem that affects the health and safety of workers causes environmental problems. The phenomenon associated with presence coal, shale, pyrite. In 2020, premature detonation incident occurred at an iron ore mine where waste material contains black carbonaceous shale units known to be spontaneous propensity properties samples shales from were examined compared Witbank Coalfield. liability indexes these correlated X-ray fluorescence (XRF) proximate ultimate analyses using linear regression. Wits-Ehac Index classification results show between medium high risk. regression analysis showed very poor correlations XRF results. most valuable relationship found relatively sulphur (greater than 3%) ground reactivity nitrate-bearing explosive emulsion. Keywords: combustion, regression, detonation, mine.

gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Reliability and Risk Assessment of Electric Cable Shovel at Chadormalu Iron Ore Mine in Iran
Nowadays, shovels play an important role in production of open pit mines and their failures result in significant production loss and considerable increase in maintenance costs. Therefore, reliability and risk analysis can help to improve production, productivity and reduce production costs. In this study, reliability of electric cable shovel of Chadormalu iron ore mine in Iran was investigated...
متن کاملDetermination of Ore/Waste Boundary Using Indicator Kriging, Case Study: Choghart Iron Mine of Iran
Estimation of ore reserves is one of the most critical aspects of mining geology. The accurate assessment of the tonnage and grade of run of mine may be the difference between a healthy profitable operation and an expensive early mine closure. The first step in ore reserve estimation is to determine the boundary of ore body or ore/waste contacts. This paper presents a specific mining applicatio...
متن کاملPlanning an Iron Ore Mine: From Exploration Data to Informed Mining Decisions
The process of developing an iron ore mine from exploration data through to informed mining decisions provides an example of a Complex Adaptive System. The detailed composition of an ore body (expressed as a “block model” of regularly spaced rectangular blocks) has to be estimated from initially sparse exploration data, based upon a limited number of drill holes. As planning proceeds, the data ...
