KBD7、KBD5电磁辐射观测仪在采煤工作面的应用

Application of CKBD7, KBD5 Electromagnetic Radiation at Coal Face

鹤岗分公司规定各矿凡是开采深度达到300 m的所有煤层进行开采都必须严格按照有冲击地压煤层管理,新陆煤矿采深达到550～770 m。2007年经中国矿业大学鉴定新陆煤矿为弱冲击矿井,因此新陆煤矿成立专业防冲队并购置KBD7、KBD5电磁辐射仪对矿采掘工作面进行现场观测。

Hegang branch requires each mine to reach 300 m depth of all coal mining must carriy out strictly in accordance with a rock burst seam management.Xinlu Coal Mine mining depth reaches 550～770 m.In 2007 it was identificated by China University of Mining for the weak impact mine,so an team set up and acquisited KBD7,KBD5 electromagnetic radiation instrument for on-site observations at mining face.
