A new type of coal core sampler

摘要: 煤心采取质量是影响煤田地质勘探成果质量的重要因素,本文介绍一种深孔(500~1000m)煤心采取器,其煤心采取率达到90%以上,且能保证煤心样品的代表性。

Abstract: The exploration quality is greatly influenced by the quality of coal core sampling.It is introduced that a kind of core sampler for deep holes at the depth of 500-1000 m,with the sampling tate of 90%.
