摘　　要：可调谐半导体激光光谱吸收检测技术(TDLAS)与遥测技术相结合作为一种新型的检测手段,将会克服目前煤矿灾害气体检测过程中存在的很多问题,特别是对采空区、工作面上隅角等甲烷气体易聚集而现有设备无法检测的区域。该技术将会大幅的提高煤矿检测水平,使煤矿安全监测问题得到进一步的完善。Tunable diode laser absorption spectroscopy detection technique（ TDLAS） technology combined with telemetry as a new mean of detection,will overcome many problems that exist in the mine disaster gas detection process currently,especially for mined-out area,upper corner angle and other gas gathering regions that equipment can not detect. The technology will significantly improve the level of mine detection,mine safety monitoring so that the problem is further improved.
