摘要
顶板岩石相当于一种自然γ射线放射源,而γ射线穿透煤层之后的剩余量与煤层的厚度存在一定的数学关系,通过这个原理设计了一套基于MCS-51单片机的自然γ射线顶煤厚度测量仪。实验证明,该顶煤厚度测量仪具有较好的测量精度,能够很好地满足煤矿需求。
Roof rock is equivalent to a kind of natural gamma ray source, and in this case of the residual amount of gamma rays after it penetrates the coal seam has a certain mathematical relationship with the thickness of coal seam, through use the principle to design a set of natural gamma ray top-coal thickness measuring instrument based on MCS-51 single chip microcomputer. Experiments show that the top-coal thickness measuring instrument has good measuring precision, and can well meet the demand of coal mine.
