【摘要】：导水断裂带高度是留设防隔水煤(岩)柱和水体下采煤安全性评估的重要参数,对矿井安全生产、保水采煤和生态保护具有重要实用价值。对经验法、现场实测、物理模法和数值模拟法等导水断裂带确定方法进行了总结、对比和实例分析,总结了各种方法的实用条件、优缺点,建议采用2种及以上综合观测和探测方法,以相互验证。以现场钻孔漏失液观测和钻孔电视观测为主,物探探测方法为辅来确定导水断裂带高度,采用物理模拟或数值模拟方法作为辅助研究方法从面和立体角度进行覆岩破坏规律动态研究,形成以点到面再到空间的全方位综合探测与分析技术方法体系,为煤(岩)柱合理留设、水体下安全采煤提供了重要依据和技术支撑。
[Abstract]:The height of water-conducting fault zone is an important parameter to evaluate the safety of coal mining under water column and water body, which is of great practical value to mine safety production, coal mining with water conservation and ecological protection. This paper summarizes the methods of determining the water-conducting fault zone, such as empirical method, field measurement method, physical model method and numerical simulation method, and summarizes the practical conditions, advantages and disadvantages of these methods. Two or more integrated observation and detection methods are recommended to verify each other. Based on the observation of field drilling leakage and borehole television observation, the geophysical exploration method is used to determine the height of the water-conducting fault zone. Using physical simulation or numerical simulation as the auxiliary research method, the dynamic study on the failure law of overburden is carried out from the angle of plane and solid to form an omnidirectional comprehensive detection and analysis technique system based on point to surface and then to space. It provides important basis and technical support for coal (rock) pillar reasonable setting and safe coal mining under water body.
