Risk prediction based on a time series case study: Tazareh coal mine
In this work, the time series modeling was used to predict the Tazareh coal mine risks. For this purpose, initially, a monthly analysis of the risk constituents including frequency index and incidence severity index was performed. Next, a monthly time series diagram related to each one of these indices was for a nine year period of time from 2005 to 2013. After extrusion of the trend, seasonali...
متن کاملImpacts of coal shrinkage, permeability and petrography on gas regime in mines Case study: Tahmoor coal mine, NSW, Australia
The volumetric changes in the coal matrix (Coal Shrinkage), permeability under various gas environment conditions as well as perographical properties were studied in the laboratory. The shrinkage and permeability of coal were examined with respect to changing gas type and confining pressures. The shrinkage tests were carried out in high-pressure bombs while the permeability study was conducted ...
متن کاملInvestigating the effect of fractures on unusual gas emission in coal mines; case study of Parvadeh coal mine, Iran
In the present study, an investigation was carried out on Parvadeh coal mine in Tabas, Iran, to survey the effect of fractures on unusual methane gas emission in coal mines. This coal mine was chosen for investigating because of its high methane gas content in the coal body and available data from sensors in desired locations. Gas concentration monitoring programs were carried out at the mine s...
متن کاملHigh-tech coal mine canary.
High-tech coal mine canary One of coal mining's earliest systems for warning of the presence of methane gas, the canary in the coal mine, though low-tech, was extremely effective and rather easy to read: if the bird died, miners had to get out of the shaft. Today, the search for means to monitor for signs of danger continues. At an annual checkup, one could be given a whole battery of tests, ea...
متن کاملCO dispersion from a coal fire in a mine entry
Five mine fire experiments were conducted in a 2.08 m high and 2.90 m wide, ventilated mine entry in the National Institute for Occupational Safety and Health (NIOSH)’s Safety Research Coal Mine (SRCM) to determine the effect of the dispersion of carbon monoxide (CO) on mine fire detection. CO measurements were made at distances from 7.6 m to 45.2 m downwind from the fire with diffusion mode CO...
