摘要
基于某矿综二面风巷变向点附近的地质条件和开采技术条件,分析了该区域冲击地压频发的原因,可为后续工作面制定针对性防冲措施提供理论依据,保证工作面安全回采。
Based on geological and mining condition of areas near the direction-changing point of returned airway beside the second mechanized surface of a certain mine,the reasons of rockburst frequently occur in this area is analyzed,which provides theoretical basis for working out pertinent burst-prevention measures for subsequent working face and ensures safe backstopping mining on working face.
