摘要
煤矿井下环境复杂,可能存在高瓦斯气体,而掘进机作为主要的煤矿设备,若其电控箱体密封性不好,一个火花就可能引起爆炸,造成人员伤亡,影响正常的生产。因此对每台掘进机的电控箱体做密封性试验,显得尤为重要。
Coal mine underground environment is complex,there may be high gas and the main coal equipment,roadheader must have a good sealing and a spark might explode,causing casualties,affecting the normal production.So for the sealing test of each roadheader electric cabinet is particularly important.
