大探距坑透仪是针对我局现采侏罗系煤岩电阻率低,传统坑透仪不能传透,对地质异常反映不显著而研制的,分辨率平均提高了30dB。EBJ—160HN半煤岩掘进机则是针对大同矿区岩石坚硬,切割硬度大的特点研制的大功率半煤岩巷掘进机,在永定庄矿进行的井下工业性
Detecting pit through the instrument is against my bureau Jurassic coal mining is low resistivity, the traditional pit through the instrument can not be transmitted, the geological anomalies were not significantly developed, resolution increased by an average of 30dB. EBJ-160HN semi-coal roadheading machine is a high-power semi-coal rock roadheader developed according to the characteristics of hard rock and large cutting hardness in Datong Mining Area. It is used in the downhole industrial
