Semi-mechanised blasting gallery mining is a sustainable option to achieve higher production and productivity from underground thick coal seams. Judicious design of underground blasting gallery panel requires understanding of stress distribution on barrier pillars during different stages of extraction. This paper presents a study of stress distribu...
Conference Paper
About 50% of coal reserves in India are available in thick seams. A comprehensive evaluation of ground behaviour is a prerequisite for maintaining an efficient production, especially during one lift extraction of thick coal seams under strong and massive roof strata. It is rather complicated to predict the characteristics of strata response to mini...
Article
About 50% of coal reserves in India are in seams thicker than 4.5m, which come under the category of thick seams, the exploitation of which is consistently posing challenges to the mining engineers. Extraction of thick seams by conventional hand section method is neither productive nor effective from the conservation point of view. The percentage o...
Article
Selection of a suitable mining method for economical and safe underground extraction of a thick coal seam is an extremely delicate process and brings a number of geo-technical parameters into consideration. In fact, single lift working of full thickness of a thick coal seam has always a verge over the multi slice working due to favorable economics...
