煤矿井下避难硐室防护墙设计

Protecting Wall Design for Refuge Chamber in Underground Coal Mine

在对煤矿井下避难硐室的防护墙的防护功能进行研究的基础上,确定了防护墙的结构形式,提出了防护墙的施工技术要求,通过防护墙抗爆炸冲击波压力、冲量、矿山压力计算,提出防护墙厚度的计算方式,对避难硐室防护墙的设计具有重要意义。

On the basis of protection function research of refuge chamber protecting wall in underground coal mine,the structural form of protection wall was determined,and the construction technique requirements of protecting wall were put forward. Through the calculation on the antiknock shockwave pressure,impulse and ground pressure of protecting wall,the calculation mode of protecting wall thickness was proposed,which had great significance to the protecting wall design of refuge chamber.
