Characteristics of mine pressure behaviors at fully-mechanized face for medium-thickness coal seam with Chenghe mining area
摘要
Abstract
In order to solve the existing problems of hydraulic powered support selection rationality of the exploitation process for a fully mechanized coal face of typical medium-thickness seam in No. 5 Coal Seam of Chenghe Mining Area, No. 5216 fully-mechanized working face of Wangcun Mine Inclined Shaft, the characteristics of strata behavior of fully mechanized coal face in typical medium-thickness seam are researched with the methods of strata control observation. Research results; we have obtained initial caving interval of the immediate roof, initial weighting length of the main roof, periodic weighting length of the main roof, strata weighting strength, sustainable range and the related strata behavior characteristics. The certain reference is provided for hydraulic powered support selection rationality and safety reliability and highly efficient and safe mining of the similar working-face for a fully mechanized coal face of medium-thickness seam in Chenghe Mining Area.关键词
