摘要:
为研究瓦斯爆炸后瓦斯积聚体积对风门冲击载荷的影响，结合羊场湾矿井Ⅱ020612回采工作面风门实际情况，运用Fluent软件对上隅角瓦斯积聚体积为5，35，65，95，125，155，185 m3条件下的风门冲击载荷进行研究。结果表明：风门冲击载荷随时间变化出现2次峰值，第1次峰值为风门冲击载荷最大值；若风门间距离较近，则风门间的互相影响使冲击载荷形成第3次峰值。风门爆炸冲击载荷最大值与瓦斯积聚体呈现幂函数增加关系；风门达到冲击载荷最大值的时间随着瓦斯积聚体积增加呈现幂函数减小关系。研究结果可为瓦斯爆炸对风门的影响研究提供依据。
Abstract:
In order to study the influence of gas accumulation volume on the impact load of damper after gas explosion,combined with the actual situation of the damper in Ⅱ020612 mining face of Yangchangwan Mine,the Fluent software was used to study the impact load of damper under different gas accumulation volumes at upper corner of 5,35,65,95,125,155,185 m3,respectively.The results showed that the impact load of damper presented two peak values with time,and the first peak value was the maximum impact load of damper.When the distance between the dampers was relatively close,the interaction between the dampers caused the impact load to form the third peak value.The relationship between the maximum explosion impact load of damper and the increase of gas accumulation volume presented a power function increase.When the damper reached the maximum impact load,it presented the power function decrease relationship with the increase of gas accumulation volume.The research results can provide a basis for the research on the influence of gas explosion on the damper.
