电磁辐射仪在确定上覆煤柱及采空区探测中的应用

Application of Electromagnetic Radiation Instrument in Determining the Detection of Overlying Coal Pillar and Goaf

煤炭生产中留设了大量的煤柱及形成的采空区对下层煤的开采造成了很大的安全隐患。文章使用电磁辐射仪对煤柱及采空区进行探测,找出了煤柱及采空区的位置,取得良好的效果,值得借鉴及推广。

Coal production has left many coal pillars and goaf which cause threat to the mining of lower coal layers. This study detected coal pillars and goafs by electromagnetic radiation instrument, found out the location of coal pillars and goafs and obtained good effect worthy of reference and promotion.
