【摘要】 多年实践经验总结表明,地面物探成果对于了解煤层赋存状态、矿井主要构造等宏观内容十分有益,但对于规模较小的地质异常体的判断存在较大误差。在地面物探成果的指导下,开展井下物探,可以达到对小型地质异常体的精细探测,提高准确率,降低误报率和漏报率,减少盲目性,对于保证安全生产起到重要作用。根据矿井环境条件,采用不同原理的物探技术组合开展井下综合物探,有利于分析判断物探成果。以实例说明地面三维地震与井下瞬变电磁法、地震波法联合物探对于探测隐伏小型构造十分有效。更多还原

【Abstract】 Years of practice showed that surface geophysical exploration fruit was favorable for understanding coalseam occurrence state and main tectonic of mine,but there was major error in judging small tectonic body. Underground geophysical exploration would realize detailed detection for small tectonic body,improve accuracy and reduce misinformation and failure ratio. According to mine environment condition,applying underground comprehensive geophysical exploration with different theory was favorable for analyzing exploration result. An example was used to show the effectiveness of applying surface 3-d seismic,underground transient electromagnetic method and seismic-wave method to detecting hidden small fault.更多还原
