深部开采对电气防爆影响的探讨

Influence on explosion-proofing of electrical equipment for large mining depth

文章着重论述了随着矿井开采深度的增加,大气压力增加对井下电气防爆的不利影响,提出在深井防爆产品的设计中应有更高的安全裕度。

With the increase ofthe mining depth, the atmosphere pressure is increasingand it has bad effect on explosion proofing property ofelectrical equipment. In the paper the design methodfor explosion proofing electrical equipment are pre-rented and the equipment must have bigger safety factorfor the large mining depth.
