摘要
为解决澄合矿区5号煤典型中厚(1.5～3.5 m)煤层综采开采中存在的液压支架选型合理性等问题,文中以澄合矿区具有典型中厚煤层的王村煤矿斜井5216综采工作面地质条件为研究背景,通过现场矿压观测手段分析研究了矿压显现特征。研究结果:得出了澄合矿区典型中厚煤层综采工作面直接顶初次垮落步距、老顶初次来压步距、周期来压步距、来压强度以及来压持续距离等矿压显现特点,从而为澄合矿区中厚煤层综采支架选型合理性、安全可靠性以及相似工作面的高效安全开采提供科学依据。
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.
