采煤界都知道诸如页岩等岩石具有伽玛放射特性,地下采煤广泛利用这特性识别煤和废岩。但这技术最近才用于露天采煤,美国西佛吉尼亚洲贝克莱特殊设备供应商SHM(超级阶坡采煤机)公司于2006年首次推出了伽玛探测系统。基于利用自然伽玛放射原理作为连续采煤机或长壁滚筒采煤机割头 The coal industry knows that rocks such as shale have gamma emission characteristics. Underground coal is widely used to identify coal and waste rock. However, this technology has only recently been used for open pit mining. The SHM (Super Slope Shearer) company, a supplier of Beckley special equipment in West Virginia, introduced the gamma detection system for the first time in 2006.
