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。
基于某礦綜二麵風巷變嚮點附近的地質條件和開採技術條件，分析瞭該區域遲擊地壓頻髮的原因，可為後續工作麵製定針對性防遲措施提供理論依據，保證工作麵安全迴採。
기우모광종이면풍항변향점부근적지질조건화개채기술조건，분석료해구역충격지압빈발적원인，가위후속공작면제정침대성방충조시제공이론의거，보증공작면안전회채。
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.
