煤矿井下永久避难硐室人员疏散研究
Research on Evacuation in Permanent Refuge Chamber of Coal Mine Underground
-
摘要: 以国内某矿建设的永久避难硐室为例，进行了疏散时间检验的研究。根据该矿永久避难硐室的选址，借鉴地铁应急人员疏散原理，井下人员能安全疏散条件是安全疏散所需时间小于可利用的疏散时间。以井下巷道作为疏散网络模型的基础，基于疏散过程的假设条件，可计算距离避难硐室最远的工作面人员安全疏散所需时间。计算表明，巷道的通行能力远远大于避难硐室入口通行能力，避难硐室入口存在“瓶颈”现象，导致人员滞留；工作面人员安全疏散所需时间小于可利用的疏散时间，故井下所有人员均能在此时间内达避难硐室。Abstract: A case study on evacuation time check in a permanent refuge chamber of domestic mine was presented. According to the site of permanent refuge chamber, learning from the subway emergency evacuation principles, underground personnel can safely evacuate when safety evacuation time is less than available safe evacuation time. Taking underground tunnel as the basis of evacuation network model, based on assumptions of evacuation process, safety evacuation time can be calculated for evacuating from the farthest distance working face to the refuge chamber. The result shows that roadway capacity is far greater than the refuge chamber entrance capacity, which causes bottleneck phenomenon and personnel retention. It also shows that safety evacuation time is less than the available safe evacuation time, so all the staff in underground can reach the permanent refuge chamber in time.
