摘要
我国非煤地下矿山数量大、类型多、工艺复杂,部分矿山开采历史久远,基础资料缺乏,存在矿山隐蔽致灾因素辨识不清、各矿山隐蔽致灾因素普查成果水平参差不齐等问题.研究表明瞬变电磁法具有施工便捷、低阻敏感、探测距离较深等技术特点,可以查明地下矿山历史采空区位置、范围、边界和含水性等信息,科学高效支撑非煤地下矿山蔽致灾因素普查工作.
Abstract
Due to the large number,diverse types,and complex processes of non-coal underground mines in China,some of which have a long history of mining and lack basic data,there are problems such as unclear identification of hidden disaster-causing factors in mines and uneven levels of survey results of hidden disaster-causing factors in various mines.Research has shown that transient electromagnetic method has the technical characteristics of convenient construction,low resistance sensitivity,and deep detection distance.It can identify the location,range,boundary,and water content of historical goaf in underground mines,and scientifically and efficiently support the survey of disaster-causing factors in non-coal underground mines.
