Determination of Coal Seams Depth of Erosion with Respect to the Remnants of a Key Bed in Kerman Coal Field, Iran
As a tool for exploration of concealed coal seams by modern techniques, determination of the depth of erosion of coal seams with reference to the surface of angular unconformity underlying the remnants of a key bed is conducted for the first time in coal mines of Kerman region. The angular unconformity surface (the initial surface exposure of coal seams) separates the coal seams of Jurassic age...
متن کاملEffect of Dust Suppression Measures on the Prevalence of Coal-workers' Pneumoconiosis in the Dutch Coal-mines.
The underground workers in the Dutch coal-mines have been radiographed (70 mm.) seven times since 1949. The prevalence of coal-miners' pneumoconiosis shows a continuous decrease in all age groups. To evaluate the effect of the intensive system of dust suppression over this period a cohort analysis was made of the proportion ofmen with pneumoconiosis with the same number of years of exposure und...
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 کاملOverview of the Coalbed Methane Potential of Tertiary Coal Basins in the Interior of British Columbia
The interior of British Columbia contains a number of fault bounded Tertiary basins that contain coal (Figure 1). This paper brings together existing data that aids in assessing the coalbed methane (CBM) potential of the basins and presents new data on some of the basins. The CBM potential of the basins ranges from up to 1 tcf at Hat Creek to a few bcf at Coal River. In all cases the resources ...
