摘要
煤层工作面中的断层、煤层变薄区等是影响煤矿安全生产的主要地质因素。目前主要采用无线电坑透、地震及槽波CT等方法,实现巷道工作面内的二维层析成像,以查明采前工作面的地质条件及异常特征。多个工作面成像实践表明,受不同探查方法的施工条件所限,通常采用无线电坑透法对工作面进行普查,判断面内基本地质条件;对于构造复杂区域可采用地震类CT方法进行精细探测。根据不同透射CT方法的特点,进一步讨论了其研究和发展方向。
Fault,coal thinning zone in coal face are main geological factors impacting coalmine safety in production. At present,the radio wave penetration,seismic and channel wave CT are mainly used to realize roadway face 2D tomographic imaging,identified working face geological condition and anomalous features before extraction. Multiple working faces imaging practices have shown that restricted by different prospecting operation conditions,usually through radio wave penetration carries out prospecting to estimate face basic geological condition; as for structurally complex areas can use seismic kind CT to carry out detailed prospecting. According to different transmitting CT peculiarities,have further discussed studies on them and development orientations.
