Thick coal seam no. 3, block V, Lupeni mine was mined by longwall top coal caving (LTCC). After the coal mining, the ground surface underwent continuous subsidence, but since 2008, three sinkholes have appeared on the surface with important dimensions, atypical for the geo-mining conditions in this coal basin. This article is a synthesis of the study meant to decipher the geo-mechanical

Jan 01, 2018 Abstract. Due to its high energy generation potential, coal is widely used in power generation in different countries. Although, the presence of carbon, hydrogen and sulfur in coal facilitates the energy generation in coal combustion, some pollutants including COx, SOx, NOx, particulate matter (PM) and heavy metals are accumulated in air and

While the successful reclamation of coal post-mining land sites in Indonesia has been evaluated, no cost-benefit analysis has been carried out on the reclamation of mined land, and the impact of the reclamation work has not been determined. The results of this case study indicate that reclamation work is not an emission-free process, but that the benefits delivered from this work are considerable

modeling of underground coal mining processes - nasa/ads

This paper presents a comprehensive simulation model of underground coal mining processes in a fully mechanized longwall mining face. A number of simulation experiments were performed. The face productivity is estimated as a function of various factors such as the technical parameters of mining machines, face length, gas factor, shearer operation mode, distributed geomechanical characteristics

With the gradual strengthening of national coal mine safety inspection work. But people still lack safety awareness in the coal mine production process. The lack of attention to safety management has led to many safety accidents in the production process of the coal mine industry. Effective supervision of the coal mine production process is of great significance to protect the safety of coal
