There are two major coal-bearing formations in the Peace River Coalfield in northeastern British Columbia, The Gates and the Gething. The younger Gates Formation hosts to the two major coal mines that have operated in the area; therefore there is some coalbed methane (CBM) information available for the formation. In contrast there is very little CBM information available for the older Gething F...

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 ...

This paper addresses the question of whether adopting safety culture improves hazard prevention in enterprises characterized by high primary risk. To answer this question, sample underground coal mines were examined to investigate the basic elements of the safety culture of employees. This paper presents the results of a diagnosis of the basic elements of the safety culture of supervisors (midl...

Two hundred samples were taken from various sites in Iran, including coal storage areas, waste water in the Tabas and Zirab coal mines, and sulphur containing acid springs in Ramsar and Abask , and were screened for Thlobacillus ferruuxidans. During this investigation , seven strains were isolated which could oxidize sdphm , pyrite , thiosdphate and ferrous iron as the sole energy source. Macr...

Epidemiological studies indicate that living in proximity to coal mines is correlated with numerous diseases including cancer, and that exposure to PM10 and PM2.5 components could be associated with this phenomenon. However, the understanding of the mechanisms by which PM exerts its adverse effects is still incomplete and comes mainly from studies in occupationally exposed populations. The aims...

OBJECTIVE The aim of this study was to test for differences in injury rates for contractor-operated underground coal mines relative to owner-operated mines in Kentucky, controlling for other covariates. METHODS We used disparities between MSHA contractor data and surface reclamation permit data to identify mines operated by contractors. We then used negative binomial regression to estimate in...

Rock fall related accidents continue to occur in coal mines, although artificial support mechanisms have been used extensively [1]. Roof stability is primarily determined in many underground mines by a limited number of methods that often resort to subjective criteria. It is argued in this paper that stability conditions of mine roof strata, as a key factor in coal mines, must be determined by ...

Duggan, M. J., Soilleux, P. J., Strong, J. C., and Howell, D. M. (1970). Brit. J. industr. Med., 27, 106-109. The exposure of United Kingdom miners to radon. Airborne radon has been recognized as a probable cause of lung cancer since the epidemiological studies made in the mining communities of Schneeberg and Jachymov during the 1920s and 1930s. Uranium miners are generally exposed to high conc...

This paper studies the application of virtual simulation technology in coal mine, and proposes threedimensional virtual simulation training system for coal mines. This system mainly includes “finger oral” and reduction of accident cases. This paper describes the characteristics and development process of three-dimensional virtual simulation training system which can achieve three-dimensional vi...
