摘　　要：为有效保证采煤工作面的生产作业安全,提出一种瓦斯浓度检测装置的设计:在采煤机"主停闭锁"按键解锁时,通过本安电池模块给瓦斯检测模块供电,瓦斯检测模块开始检测工作面的瓦斯浓度,当瓦斯浓度在安全范围内时,瓦斯闭锁触点闭合,采煤机可正常上电。工业性试验结果表明:该装置在采煤机上电前可靠地检测了工作面的瓦斯浓度,且在检测完成后采煤机可以正常启动上电,有效提高了采煤工作面的生产作业安全。To effectively ensure the safety of production operations in the working face of shearer,present the design of a gas concentration detection device： when the shearer＇s button of main stop locking is unlocked,the gas detection module starts to detect gas concentration on power by intrinsically safe battery module. The gas locking contact closures and shearer is normal powering when the gas concentration is in the safe range. The results of industrial experiment showed that： the device can reliably detect gas concentration before the shearer on power,ensure shearer can start on power after the detection and effectively improve the security in the working face of shearer.
