两硬特厚煤层综放采场矿压显现规律实测研究

针对平朔矿区井工二矿两硬特厚煤层开采条件,通过现场矿压实测,从支架工作阻力特性、顶板来压特征、超前支承压力分布、顶煤运移规律等方面分析9#煤层矿压显现规律,为类似地质条件下综放工作面顶板管理及安全开采提供实测依据。

Study on Strata Behavior Regularity of Fully-mechanized Caving Face with Thick and Hard Coal Seam

With the engineering geological conditions of buried depth and hard seam and roof in pingshuo mining area No.2 mine is researched,strata behavior regularity is analyzed from the aspects of pressure from the features of the old roof,support resistance situation and the effective work resistance and so on,at last,provides the technical advantage and theoretical support for high yield,efficient,safe production of other fully-mechanized caving face.
