摘要
Abstract
There are small coal mines in the process of mining of Shuanglong Coal Mine.In order to accurately detect the damage area of small coal mines in Shuanglong Coal Mine and provide accurate geological data for Shuanglong Coal Mine,six directional drilling holes are constructed in the return airway by using directional drilling technology to rapidly and efficiently detect damage area of small coal mine.The results show that the directional drilling technology for goaf detection is feasible,and it has the advantages of fast and high efficiency and high precision.关键词
