摘要/Abstract

摘要： 采用力学分析、数值模拟、现场监测等手段研究了动压条件下煤矿工作面纵跨巷道围岩的稳定性。基于岩石材料的流变特性，采用弹塑性理论分析纵跨巷道的围岩受力特征，求出了巷道围岩的应力各分量的解析解；数值计算表明，巷道受工作面前方支承压力和侧向应力的叠加应力影响，随着工作面的推进，超前支承压力对其影响逐渐减弱，侧向应力将长期影响巷道围岩的稳定性。确定了煤层工作面端头侧向应力作用下的流变效应是影响跨采巷道稳定性的重要因素之一。采用注浆封堵技术，确保了巷道围岩不被软化，保持了巷道围岩的强度和承载能力，达到了控制巷道围岩稳定性的效果。

Abstract: Aiming at the special situation of working face across floor roadway,this paper apply mechanics analysis，numerical simulation，field practice and research of deep mining across the mining under the condition of the stability of surrounding rock of roadway.The results show that the stress of the roadway surrounding rock can be calculated each component by theory of elastoplastic analysis across the force characteristic of surrounding rock in roadway based on the rheological properties of rock material.Numerical calculation shows that roadway influenced by mining the front abutment pressure and the lateral stress superposition of stress influence.And with the working face advancing，weakening the influence of abutment pressure，lateral stress will affect the stability of surrounding rock of roadway long-term.Determine the rheological effect of coal seam working face end under the action of the lateral stress is one of the important factors that influence across mining roadway stability.Mining water seepage grouting seal technology，to ensure that the surrounding rock of roadway is not soften，maintain the strength of surrounding rock of roadway and carrying capacity，achieved the effect to control the stability of surrounding rock of roadway.

Key words: Working face across floor roadway, Rheological property, Lateral abutment pressure, Crack blocking technology
