in the present study, 45 rainwater samples were collected from february to december 2012 on event basis in east bokaro coal mining environment. physico-chemical and major ionic compositions of rainwater samples as well as water soluble major ion composition were analyzed to employ principle component analysis for source identification. the average ph value was recorded 6.1 and varied from 5.1 t...

The East Bokaro Basin of the Damodar valley is a potentially prospective CBM (coalbed methane) play having significant cumulative coal seam thickness, in-situ gas content, vitrinite percentage, and adequate thermal maturity. Successful recovery needs detailed understanding organic pore structures/networks, storage properties flow mechanism. present work attempts to systematically investigate fo...

The dynamic monitoring of fire area is particularly important in the controlling of underground coalfield fire. This paper took the Xinjiang Shuixigou coalfield fire area as an example, through the normalized processing of the multi-temporal thermal infrared images a generalized single-channel algorithm was used to retrieval the surface temperature. Combined with the method of single band optim...

This paper explores how the impact of retirement on self-assessed illness varies spatially across the UK. Curves of age-specific limiting long term illness rates reveal a 'retirement kink'-where the rise in illness rates with age slows or declines at retirement age indicating possible health improvement after retirement. The kink is negligible in the affluent South East and most prominent in th...

Coal fires are common and serious phenomena in most coal-producing countries in the world. Coal fires not only burn valuable non-renewable coal reserves but also severely affect the local and global environment. The Rujigou coalfield in Shizuishan City, Ningxia, NW China, is well known for being a storehouse of anthracite coal. This coalfield is also known for having more coal fires than most o...
