煤矿掘进巷道爆破作业对通风构筑物的破坏作用
The damage effects on ventilation structures in mine excavation roadway during blasting operation
-
它不仅与冲击波的作用情况有关，而且与通风构筑物的形状、大小、自振周期等因素有关。
It is a very complicated problem that is not only related to the shock wave interaction , but also to the shape , size and natural frequency of the ventilation structure .

该系统是数字化矿山的一个子系统，它具有自动绘制通风网络图、自动进行节点标注、自动绘制通风构筑物、任意巷道数据查询、数据可视化显示和通风系统仿真等功能。
The function of the system contains the auto-plotting for ventilation network map , and the automatic stanchion for nodes , and the auto-plotting for air-construction , and querying the parameter of tunnels , and system-simulating for ventilation system .
