摘要
我国煤矿井下复杂的地质条件,尤其是松软煤层及断层褶皱等发育地带,很容易发生钻孔跨塌或钻不进去等情况。既浪费时间还增加了劳动强度。因此在钻探工程中,为避免钻孔报废,首先应针对各类型复杂地层进行分析,了解其形成的原因,然后根据精准的勘探方法,选择适合的钻进技术实现目标。
The complex geological conditions of China's underground coal mines,especially the soft coal seam and fault folds and other development zones,it is easy to occur drilling collapse or drilling failure,etc.It wastes time and increases labor intensity.Therefore,in drilling engineering,in order to avoid drilling scrap,it is necessary to analyze various types of complex strata first,understand the causes of their formation,and then select suitable drilling technology to achieve the target according to accurate exploration methods.
