浅埋煤层近距离采空区隐蔽火源探测及控制技术

Hidden Fire Detection and Control Technology in Shallow Distance Seam Group Gob

针对陕西建新矿近距离煤层群采空区遗煤自然发火规律及自燃原因分析及隐蔽高温区识别难度和危害的研究,采用温度法火源高温点探测技术对遗煤自燃高温区域进行判定。通过检测孔采集气体分析验证,采取基于高分子胶体防灭火为主的快速控制技术,成功治理复杂漏风条件下的近距离煤层群火源高温区域。

In view of the goaf spontaneous combustion laws and causes analysis for Shaanxi Jianxin Coal Mine close distance coal seams spontaneous combustion and the study about hidden high temperature area identification difficulty and the harm,the high temperature point fire detection technology is used to judge coal spontaneous combustion and high temperature zone. By detecting the hole collecting gas analysis and validation,the fast control technology polymer- based colloidal is obtained,which successfully controls close distance seam group fire source high- temperature region under condition of complex air leakage.
