摘要
由煤矿采空区引起的安全事故一直是煤矿的主要事故之一,可能造成突水、发火等事故,这就需要首先对采空区进行探测,了解其发育状况,从而为及时处理煤矿地质灾害、有效预防煤矿事故提供良好的地质依据,但矿区一般地电干扰严重,传统的大线框瞬变电磁仪受干扰影响较大,而采用小线框瞬变电磁仪在某矿区进行采空区探测,取得了较好的效果。
Safety accidents caused by coal mine goaf have been the major accidents in coal mine,it can cause sudden water,fire and other accidents. This will need to detect the goaf to understand its development status,so as to deal with the coal mine geological disasters in time,to provide a good geological basis for accidents prevention of coal mine effectively. But in general geoelectric interference seriously impacts the effect,the traditional large wire frame transient electromagnetic instrument is influenced by the interference. By using the transient electro-magnetic（ TEM） instrument of the small coil in a certain mine area to detect the goaf,thus,achieved good results.
