在对大倾角综采工作面矿压显现规律及岩层移动特征研究的基础上，结合实际观测，提出了大倾角综采工作面支护系统（即基本顶-直接顶-支架-底板）相互作用关系，并对该支护系统稳定性进行分析。以郝家沟煤矿1301综采工作面为工程背景，研究分析了大倾角煤层综采工作面支护系统的稳定性及控制措施，为该类地质条件下综采工作面的安全、高效生产提供了技术保障和实践经验。
在對大傾角綜採工作麵礦壓顯現規律及巖層移動特徵研究的基礎上，結閤實際觀測，提齣瞭大傾角綜採工作麵支護繫統（即基本頂-直接頂-支架-底闆）相互作用關繫，併對該支護繫統穩定性進行分析。以郝傢溝煤礦1301綜採工作麵為工程揹景，研究分析瞭大傾角煤層綜採工作麵支護繫統的穩定性及控製措施，為該類地質條件下綜採工作麵的安全、高效生產提供瞭技術保障和實踐經驗。
재대대경각종채공작면광압현현규률급암층이동특정연구적기출상，결합실제관측，제출료대경각종채공작면지호계통（즉기본정-직접정-지가-저판）상호작용관계，병대해지호계통은정성진행분석。이학가구매광1301종채공작면위공정배경，연구분석료대경각매층종채공작면지호계통적은정성급공제조시，위해류지질조건하종채공작면적안전、고효생산제공료기술보장화실천경험。
Combines with the actual observation on the foundation of study on mine pressure behavior and rock movement characteristic of great dip angle full-mechanized mining face,points out the interaction relations of support system on great dip angle fully mechanized coal mining face (that is basic roof-direct roof-support-floor),and analyzes the stability of the supporting system.Takes No.1301 full-mechanized mining face in Haojiagou coal mine as the example,studied the stability of greater pitching coal seam full-mechanized mining face support system and the control measures.As the geological conditions,provides the theoretical support and practical experience for the safety and high efficient production of the full-mechanized coal mining face.
