摘要
本文综合运用理论分析和现场实测相结合的研究方法,对铺龙湾矿8103综放工作面末采阶段顶板运动规律及矿压显现进行了深入研究。分析了正常放煤和末采阶段铺网过程中顶板运动规律及矿压显现差异。初步研究了截割回撤通道过程和支架正式回撤过程中,基本支架控顶区顶板压力显现规律。
This paper comprehensively uses the research method of combining theoretical analysis and field measurement to deeply study the roof movement law and ground pressure behavior in the final mining stage of 8103 fully mechanized mining face in Pulongwan Mine.The law of roof movement and the difference of ground pressure behavior in the process of normal coal drawing and net laying in the final mining stage are analyzed.The behavior law of roof pressure in the roof control area of the basic support during the process of cutting back passage and the formal withdrawal of the support is preliminarily studied.
