摘要
地下矿山通风主井(竖井)是井下第二个应急安全出口.但由于井内梯子间狭窄、折返式的楼梯及超深的井道,使得井下人员逃生困难,井上救援时有些通风主井不能投入水泵等设备深入井下急救.广东昌泰石矿场对通风主井进行了革新,装备螺旋式人行斜坡道,可悬吊较大型的机电设备深入井下,使得井下应急逃生与井外救援迅速.
The main ventilation shaft of the underground mine is used as a second emergency exit. However, due to the narrow and turn-back arrangement of its staircases, as well as to the ultra-deep wells, it is difficult to exit the mine and per- form a rescue work by installing equipments like pumps in the ventilation shaft in emergence. Therefore, the engineers of Guangdong Changtai Mine have made innovations to the main ventilation shaft by building a spiral ramp passage, which makes possible a smooth personnel passage and greatly facilitates the rescue work. Using this passage, large-sized rescuing equipments can be put into the well for rescue work.
