Construction of high-pressure adsorption isotherm: A tool for predicting coalbed methane recovery from Jharia coalfield, India

Potential Coal and Coalbed Methane Resource of the Telkwa Coalfield, Central British Columbia (93l/11)

sampling and desorption testing of fresh coal samples obtained from companies conducting exploration throughout the province. In addition methane adsorption isotherm tests arc: performed on some samples. During the summer of 1992 a project was undertaken to test coal seams intersected in the ongoing Manalta Coal Limited drilling program in the Telkwa coalfield. On-sitc activities consisted of t...

Pulmonary Function test of Mine workers exposed to Respirable Dust in Jharia Coalfield India

Respiratory chronic airway disorders and early damage of pulmonary system predict by Spirometry. Occupational exposures to coal dust affect the different systems of the body. The present study has focused on the coal workers who are continuously exposed to air pollutants such as coal dust. Study group of 170 male workers working in coal mines for more than ten years, consists of 66 non-alcoholi...

Well Evaluation for Coalbed Methane

High-Pressure Adsorption of Pure Coalbed Gases on Dry Coal Matrices

As part of our efforts to model enhanced coalbed methane recovery and CO2 sequestration in coalbeds, we have investigated the pure adsorption isotherm behavior of five dry coals namely, Illinois #6, Wyodak sub-bituminous, Pocahontas, Beulah Zap, and Upper Freeport coal. Using a volumetric technique, isotherms of pure methane, nitrogen, CO2 and ethane were measured at a temperature of 328.15 K (...

Source Apportionment of Particulate Matter (PM10) In an Integrated Coal Mining Complex of Jharia Coalfield, Eastern India, A Review

Coal based thermal power generation accounts for 44.7% of the world's electricity and coal alone provides about 80% of the total energy demand in India. Energy-intensive industries deteriorate the air quality of the residential areas due to release of different pollutants, especially a range of deleterious heavy metals like Hg, Cd, Cu, Pb, and Cr. Near about 53.3 percent of the coal produced ev...
