波状厚煤层综放开采矿压显现规律分析

Analysis on the Strata-pressure Behavior of Fully Mechanized Caving Mining in Undulate and Thick Coal Seam

摘要: 通过对郭家河煤矿1301综放面进行现场矿压观测,分析研究该综放面顶板覆岩运动特征,掌握其矿压显现规律,对麟北煤田综放面矿压显现规律研究和确定合理支架工作阻力具有一定的借鉴作用。

Abstract: Through carrying on the field strata control observation of 1301 fully mechanized caving face in Guojiahe coal mine,the movement characteristics of roof rock is analyzed,and the strata-pressure behavior is mastered too.There is certain reference in studying strata-pressure behavior and determining reasonable working resistance of support on fully mechanized caving face of Linbei coal field.
