摘要/Abstract

摘要： 针对淮北青东矿7261工作面回采巷道的复杂地质条件，通过实测获得了回采巷道的矿压显现规律，并且利用FLAC3D数值模拟软件分析了回采巷道应力分布特征，综合矿压显现规律和回采巷道的数值模拟应力分布特征，得出了巷道受工作面回采超前支承压力影响范围和侧向支承压力影响范围，根据其影响范围和巷道围岩的情况，制定回采巷道在开采期间的超前分区加固措施，确保巷道在回采期间的稳定性。结果表明：回采巷道的矿压显现规律、工作面超前支承压力分布和巷道两侧支承压力分布指导了回采巷道围岩分区动态加固支护技术，保证了7261工作面的回采巷道在开采期间的安全稳定。

Abstract: The surrounding rock stability of extraction roadway is critical under the complicated geology of the multi fault and fold . In the complicated geology of the mining roadway of the NO7261 working face take place in a coal mine in Huaibei, the paper obtains the law of mine pressure appear of extraction roadway through pratical measurement, and analyzes the characteristics of stress distribution of the mining roadway by means of FLAC3D numerical simulation software, appears comprehensive mine pressure regularity and the numerical simulation of stress distribution characteristics of extraction roadway, obtains abutment pressure impact scope and lateral abutment pressure range of mining face , sets extraction roadway during the mining of partition reinforcement measures in advance according to the scope of influence of roadways and situation of surrounding rock, then ensures the stability of the roadway during the mining. The research results show that the strata behavior regularity of the mining roadway and advance abutment pressure distribution of the working face and the abutment pressure distribution of the roadway instruct the subarea and dynamic reinforcement support of the surrounding rock of extraction roadway, and ensure the roadway during the mining of 7261 working face in mining security and stability.

Key words: The Multi Fault and Fold, The Strata Behavior Regularity, Numerical Simulation, Subarea, The Dynamic Reinforcement Support
