新兴矿已进入深部开采,且主采煤层具有煤层薄、硬度大、顶板坚硬、大倾角等特点,因此先后多次出现冲击地压事故。为了有效控制冲击灾害、降低经济损失和减少人员伤亡,对新兴矿各工作面已发生的冲击地压灾害进行统计,对冲击灾害的特征及影响因素进行分析,得到了新兴矿冲击地压是煤岩冲击倾向性强、开采深度大、地应力高、顶板坚硬和倾角大等因素综合作用的结果,为合理和有针对性制定冲击地压灾害治理方法提供了依据。
Emerging mine has entered deep mining, and the main coal seam has the characteristics of thin coal seam, large hardness, roof hard, big dip, so there have been many occasions of rock burst. In order to effectively control the impact disaster, reduce the economic losses and reduce the casualties, the paper has carried out the statistics of the rockburst disasters occurring in each working face of Xinxing Mine, analyzed the characteristics and influencing factors of the impact disasters, Rock impact propensity, deep mining depth, high ground stress, hard roof and dip angle and other factors combined results, to provide a reasonable basis for the development of a reasonable method to deal with rock burst.
