摘要
针对露天煤矿松散地层的特性,提出了一系列钻孔护壁技术方案。这些方案来源于实验室内模拟,并大都在工程实践中得以应用,并取得了良好的效果。对大部分露天矿松散地层的钻探工作具有一定的指导意义。
According to the characteristics of loose stratum in the open-pit coal mine, the author presents a series of technology schemes on drilling wall protection. These schemes are derived from simulation in laboratory, applied in engineering practice and obtained good effect, which has a certain guiding significance to drilling work of loose stratum for most open-pit mines.
