为提高矿井的安全防护水平,减少因矿难事故造成的损失,笔者以某矿山现场为研究背景,分析了该矿某采区以间距为基准设置避难硐室,及以硐室数目为基准设置避难硐室的试验方案。研究结果表明,井下人员疏散完成所需最短时间与避难硐室的分布和数量均有关系。采区的避难硐室并不是设置得越多越有利于人员疏散;若以间距为基准设置避难硐室,避难硐室设置的最佳间距为180 m;若以硐室数目为基准设置避难硐室,则按等间距设置避难硐室比以硐室间距为基准设置的疏散效果要好。
In order to improve the level of mine safety protection and reduce the losses caused by the mine accidents, the author takes a mine site as the research background, analyzes the evacuation chamber set by the spacing in a mining area of this mine, and sets asymptoms on the basis of the number of chambers Chamber test program. The results show that the shortest time needed to complete the evacuation of miners is related to the distribution and number of evacuation chambers. The evacuation chamber in the mining area is not set to be more conducive to the evacuation of personnel; if the evacuation chamber is set based on the spacing, the optimal spacing of the evacuation chamber is 180 m; if the evacuation chamber is set based on the number of chambers Room, the evacuation chamber set at equal intervals than the chamber spacing set as the reference evacuation effect is better.
