煤矿小通道快速应急逃生系统设计研究

Research on Design of Small Tunnel for Quick Emergency Escape System in Coal Mine

对于大型矿井,发生灾变后避险人员在短时间内无法安全撤离到地面,只能躲在避难硐室内被动等待救援,无法及时逃到地面,针对这一问题论文提出了将避难硐室和直通地面的逃生通道相结合起来建设的思路。结合神东矿区布尔台煤矿的采掘特点及现有的条件,设计出了一套适用于该矿区煤矿小通道快速应急逃生系统,并对该系统中提升舱的基本参数、应急逃生通道的布置及尺寸、提升系统及主要设备的参数等关键问题进行了研究。逃生系统将煤矿发生灾变后的被动救援转变为主动逃生,对减少避难硐室配套及降低矿难损失有积极意义。

For large-scale mine,the safety personnel cannot safely withdraw to the ground within a short period of time after the disaster,so they can only wait for rescue in the refuge chamber and cannot escape to the ground in time. Aiming at this problem,the author puts forward the idea of combining the refuge chamber with the escape route directly to the ground. Based on the features of mining in Buertai Coal Mine of Shendong Mining Area and the current conditions,a small channel quick emergency escape system for coal mine was designed and studied on the basic parameters of the lifting chamber,the layout and size of emergency escape route,the parameters of the lifting system and the main equipment in the system. The escape system transforms the passive rescue after the disaster in the coal mine into active escape,which has positive significance for reducing the supporting facilities of the refuge chamber and reducing the loss of mine disaster.
