According to statistics, the coal spontaneous combustion fire accounted for more than 94% of the total number of coal mine fire, of which 60% occur in gob [1]. With the mining depth increasing, coal pillar become so easy to be crushed that coal spontaneous combustion is easier to occur. The fire’s occurrence and development not only affect the safety in production and the surrounding environmen...

In early decades, rescue operation in coal mine was treated as a dangerous task. After explosions occur, when rescue workers get into the tunnel without environment conditional awareness, they are facing heavy damages due to consecutive explosions [1]. This bring the necessity to detect the status of the mine environment details such as toxic gases, high temperatures through wireless sensors to...

Based on the actual needs of the Chinese national emergency rescue base in mining areas, and in order to effectively carry out emergency rescue in coal mine disasters, this article studies the response process of emergency rescue in coal mines, the analysis and calculation methods required in the relief work for mine disasters, the functional requirements of the integrated command platform and ...

Coal with low ash content has an important role in the coal and steel industry. There are different methods to measure the ash content. The conventional method which is used in most coal mines of Iran, is to burn the coal and measure the remaining ash. A new method has been recently developed at Nuclear Research Center (NRC) of Iran, Which works on the basis of the absorption of the dual en...

R. Ganguli, J. C. Yingling, J. Sottile, Dept. of Mining Eng. and R. Kumar, Dept. of Electrical Eng. University of Kentucky, Lexington, KY 40506 ABSTRACT The capability for on-line measurement of the quality characteristics of conveyed coal now enables mine operators to take advantage of the inherent heterogeneity of those streams and split them into wash and no-wash stocks. Relative to processi...

In the deep mining, the disaster dynamic of coal petrology and gas becomes increasingly serious, dynamic coupling of coal gas disaster grows in number. However the traditional method of predicting is limited. In order to evaluate the dynamic disaster hazard level of the coal face in the deep mine, a fuzzy hierarchy comprehensive evaluation model of the coal petrology dynamic disaster on the coa...

An area of major concern in considering increased coal production and utilization is the health and safety of increased numbers of workers who mine, process, or utilize coal. Hazards related to mining activities in the past have been especially serious, resulting in many mine related accidental deaths, disabling injuries, and disability and death from chronic lung disease. Underground coal mine...

Methane is a powerful greenhouse gas and the principal component of natural gas. Coal seams often contain significant quantities of methane, and underground coal mines must ensure that methane released into the mine during coal extraction does not build to dangerous levels. This is accomplished in part through the use of large-volume ventilation systems that remove methane from the mine and rel...
