摘要
煤矿由于火灾所引起的继发性灾害已经处于非常严重的程度。本文采用数值分析方法研究井下掘进巷道内火灾所导致的继发性灾害发生的条件。得出:火灾所造成的通风阻力的变化随火灾强度增加而增加,由此造成通风量的减小。在本文所研究的火灾强度下(<1.6MW),通风量的减少最大为2%,对矿井通风量不会产生较大影响。在掘进巷道风筒被烧断情况下,在风筒的前端容易形成瓦斯聚集区,易诱发瓦斯爆炸事故。
The security situation of the coal mine is very severe,and great accident appears fre- quently,bringing about enormous loss to the people of our country.Particularly,the hazard caused by the secondary disasters which happen following the primary disasters is much severer.This paper numerically investigated the basic conditions and possibility of the secondary disaster in the coal mine caused by the mine fire in the laneway.The flow volume was decreased(<2%)with increase of the mine fire capacity(<1.6 ...
