近年来,随着地方和乡镇小煤矿的增多,斜井跑车事故也有所增加。为了搞好这些小煤矿的安全生产和防止跑车事故的发生,我们试制了这种机械式的自动防跑车装置。1982年,我们采用人为跑车的方法进行了自动防跑车装置的现场试验,取得了满意的效果。为了把该装置应用于生产,我们先后在阳城县上孔煤矿、西河乡石门口煤矿等进行了安装调试和改进,并在使用中取得了良好效果。
In recent years, with the increase of local and township small coal mines, inclined shaft sports car accidents have also increased. In order to do a good job in the safe production of these small coal mines and prevent the occurrence of sports car accidents, we tried out this kind of mechanical automatic anti-sports car device. In 1982, we conducted a field test of the automatic anti-sports car device using the method of artificial sports car and achieved satisfactory results. In order to apply the device to the production, we successively installed, debugged and improved the Shangkong Coal Mine in Yangcheng County and the Shihmenkou Coal Mine in Xihe Township, and achieved good results in use.
