掘进工作面瓦斯爆炸后矿工如何自救与互救?

答案

参考答案:

如发生小型爆炸,掘进巷道和支架基本未遭破坏,遇险矿工未受直接伤害或受伤不重时,应立即打开随身携带的自救器,佩戴好后迅速撤出受灾巷道到达新鲜风流中。对于附近的伤员,要协助其佩戴好自救器,帮助撤出危险区;不能行走的伤员,要设法抬运到新鲜风流中,撤出灾区后,要立即向矿调度室报告。

如发生大型爆炸,掘进巷道遭到破坏,退路被阻,但遇险矿工受伤不重时,应佩戴好自救器,千方百计疏通巷道,尽快撤到新鲜风流中。如巷道难以疏通,应坐在支护良好的棚子下面,或利用一切可能的条件建立临时避难硐室,相互安慰、稳定情绪,等待救助,并有规律的发出呼救信号。对于受伤严重的矿工要为其佩戴好自救器,使其静卧待救。并且要利用压风管道、风筒等改善避难地点的生存条件。
