Concentrated stress in deep coal seam is the decisive factor leading to the occurrence of rock burst, and the different stress sources cause high stress in coal seam. To fundamentally reduce the concentrated stress in coal seam that can easily cause rock burst, this paper uses the 5305 working face in Xinhe, Shandong Province, as an example for analysis. The evolution law of high stress concentration areas (coal burst-prone zones) is analysed in coal seam during face mining, combined with the occurrence characteristics and mining conditions of the working face. The stress sources that cause different coal burst-prone zones in working face are determined. Aimed at different coal burst-prone zones, a targeted prevention-control method is proposed and includes cutting off stress paths, removing stress sources and eliminating stress sources; this method is applied to the Xinhe Coal Mine. The results show that a high static load is the main cause of rock burst in the working face of coal pillar groups. The concentrated stress of coal seam in the working face of 5305 is effectively reduced by adopting dredging concentrated stress prevention method. Field monitoring shows that the microseisms and stress in the coal seam are within a reasonable range during the whole mining process, and the occurrence of rock burst in the working face is successfully avoided.

深部煤层的集中应力是导致岩爆发生的决定性因素，不同的应力源导致煤层应力偏高。为从根本上降低煤层易引起地爆的集中应力，本文以山东省新河5305工作面为例进行分析。结合工作面的赋存特征和开采条件，分析了工作面开采过程中煤层高应力集中区（煤爆易发区）的演化规律。确定了导致工作面不同煤爆区的应力源。针对不同的煤爆易发区，提出了有针对性的防治方法，包括切断应力路径、消除应力源和消除应力源；该方法应用于新河煤矿。结果表明，高静载荷是煤柱群工作面发生岩爆的主要原因。5305工作面煤层集中应力采用疏浚集中应力预防方法有效降低。现场监测表明，整个开采过程中煤层微震和应力均在合理范围内，成功避免了工作面岩爆的发生。
