【摘要】 以桃园煤矿受承压水严重威胁的10煤1066倾斜煤层工作面开采为背景,采用数值模拟方法,找出了开采对倾斜煤层底板断层活化破坏规律;利用井下高精度防爆微震监测技术,实现了倾斜煤层底板破坏深度、底板断层活化程度的三维连续动态监测,并将其监测结果用于底板突水预测预报研究;通过及时采取防水措施,使1066倾斜煤层工作面顺利通过已活化的断层,实现了承压水上煤层的安全开采,取得了显著的技术经济和社会效益。更多还原

【Abstract】 This paper applied numerical simulation to obtaining floor fault activation rule of mining 10th inclined coal-seam threatened by confined water Underground micro-seismic monitoring with high precision was used to realize 3-D dynamic and success monitoring floor damage depth and fault activation degree Monitoring results were provided for floor water-burst prediction Timely water prevention made 1066 mining face advance safely through activated fault and realized safe mining over confined water Significant technical and economic profit had made更多还原
