大倾角综采工作面支护系统稳定性分析

摘要

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.%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。
