通化矿务局苇塘煤矿一井+615车场,位于总入风井与总排风井之间。风压大,运输行人频繁,本应设置三道正向风门、两道反风门,由于巷道距离短,只设了两道正向门、一道反风门。不仅漏风严重,而且由于风压过大,矿车来往,经常撞坏风门。在通行人员时,风门打伤行人事故也累累发生。为了改变这种状况,通风段木工班的老工人在党支部的领导下,遵照毛主席“破除迷信、解放思想”的伟大教导,群策群力,经过反复试验,制成了双拉杆活底坎正反向联动风门,代替了过去单一风门。这样在同一个+615车场,利用原有的三个门垛,实际设置了三道正向门、二道反风门。这就克服了上述缺点,漏风量由187米~3/分降低到36米~3/分。
Tonghua Mining Bureau Weitang coal mine +615 yard, located between the total intake shaft and the total exhaust well. Wind pressure, frequent transportation pedestrians, this should be set to three positive throttle, two anti-wind door, due to the short distance between the roadway, only set two forward door, an anti-wind door. Not only serious air leakage, but because of the wind pressure is too large, car traffic, often hit the throttle. In the passage of personnel, the door hit pedestrian accident also occurred. In order to change this situation, under the leadership of the Party branch, the veteran workers in Ventilation Section Woodworking Class, following the great teachings of Chairman Mao on “breaking superstition and emancipating the mind”, worked together to make positive and negative double- To the linkage damper, instead of a single past the door. So in the same +615 yard, the use of the original three door stacks, the actual set of three forward doors, two anti-wind doors. This overcame the above shortcomings, air leakage decreased from 187 m ~ 3 / min to 36 m ~ 3 / min.
